How to Sign a PDF Online Free (No Printing)
The print-sign-scan workflow is one of the most frustrating leftover habits from the paper era. The contract arrives by email. You print it. You sign it. You scan it back in, hoping the home printer is online and the scanner glass is not smudged. You email the scan back, often with the file size three times bigger than the original because scanning bloats it. Twenty minutes for a signature that takes one second on paper.
iHatePDF gives you two free paths to sign a PDF in your browser. Sign PDF is the dedicated tool with full multi-party signing, audit trails, and explicit signature fields. Editly handles quick personal signatures alongside any other edits you need to make. Both produce legally valid signatures under ESIGN and eIDAS. This guide covers both methods, the three ways to create your signature, and which path to pick.
Formal or multi-party: Sign PDF → upload → set signature fields → sign and download
Quick personal: Editly → upload → click signature tool → place and download
Why sign PDFs digitally instead of print-sign-scan
- Twenty minutes becomes thirty seconds. No printer warm-up, no toner panic, no scanner queue.
- No physical infrastructure. Sign from a hotel, a cafe, a friend's laptop, your phone in the back of an Uber.
- The output is clean. Scanned signed pages are blurry, skewed, often bloated to 10 MB for a 1 MB document. A digitally signed PDF stays crisp.
- Legally identical. ESIGN (USA) and eIDAS (EU) treat electronic signatures as equivalent to handwritten ones for the vast majority of contracts and agreements.
- Auditable. Digital signatures can include timestamps, signer information, and tamper-evidence that paper signatures cannot.
- Multi-party friendly. One PDF can collect signatures from multiple people across cities without a single courier.
Method 1: Sign PDF (formal and multi-party)
The dedicated tool, best for contracts, agreements, NDAs, and anything that needs a clean signing workflow with optional multi-party support.
- Open Sign PDF and drag in your file. Cloud import works from Google Drive, Dropbox, and OneDrive. Files up to 80 MB, with or without an account.
- Place your signature where it is needed. You can also add the date, your initials, or your printed name as text, in any language.
- Create your signature: type, draw, or upload a signature image (see the section below).
- Apply your signature. To have others sign too, choose Send for signature: add up to 20 signers by email and each one gets a secure link. The finished PDF comes with an Audit Trail and a Certificate of Completion.
- Download the signed PDF. The signature is embedded in the file and the document is ready to send back.
Method 2: Editly signature (quick personal use)
When you want to sign quickly while you edit. Editly has the same signature tool as Sign PDF (draw, type, or upload), plus a pen for freehand marks, so you can sign the document and move on in the same session.
- Open Editly and upload your PDF, Word document, image, or any other file you would normally print to sign.
- Click Signature in the toolbar, or the pen tool for a freehand mark.
- Draw, type, or upload your signature. To draw, use your mouse, finger, Apple Pencil, or Surface Pen.
- Place it wherever needed. Add a date or any other text in the same session.
- Click the export button and download the signed PDF, or export as Word or image if the recipient needs a different format.
Three ways to create your signature
1. Type your name in a signature font
The fastest option. Type your full name and pick from several signature-style fonts (cursive, italic, formal). Good for routine documents where a stylised typed signature is acceptable. Consistent across all your documents. The signature fonts are designed for Latin letters, so for a name in Chinese, Arabic, Hindi, or another script, draw it or upload an image instead.
2. Draw your actual signature
The most authentic option. Sign with your mouse on a desktop, your finger on a phone, or your Apple Pencil or Surface Pen on a tablet. The drawn signature looks like a real handwritten signature on paper. Best for contracts, legal documents, and anywhere the signature should look genuine.
3. Upload an image of your signature
The most consistent option if you sign frequently. Sign once on a piece of paper, photograph or scan it, save as a PNG with transparent background, and reuse forever. Every signed document looks identical to your real-paper signature.
When to use which method
| Scenario | Recommended |
|---|---|
| Contract needing multiple signers | Sign PDF |
| Formal agreement (NDA, lease, employment) | Sign PDF |
| Need audit trail for compliance | Sign PDF |
| Quick signature on a form you are also editing | Editly |
| One-off acknowledgment or receipt | Editly |
| Signing a scanned form that also needs text fields filled | Editly |
| Need output in Word or image format too | Editly |
Legal validity: ESIGN, eIDAS, and what makes a signature count
Two major regimes govern electronic signatures globally:
- ESIGN Act (USA, 2000). Makes electronic signatures legally equivalent to handwritten signatures for most interstate and federal commerce, provided the signer intends to sign and consents to electronic transactions.
- eIDAS Regulation (EU, 2014). Defines three tiers: Simple Electronic Signature (SES), Advanced Electronic Signature (AES), and Qualified Electronic Signature (QES). SES is the most common and is sufficient for the vast majority of business and personal contracts.
iHatePDF signatures meet the Simple Electronic Signature standard, which is enforceable for the majority of contracts including: most commercial agreements, NDAs, employment contracts, lease agreements, vendor agreements, consent forms, and acknowledgments.
When a Simple Electronic Signature is NOT sufficient: wills, divorce papers, court orders, some real estate transactions (varies by jurisdiction), certain regulated industries (varies by country). For these specific cases, a Qualified Electronic Signature from a certified provider is required. For everyday business and personal documents, simple electronic signatures are widely accepted.
Electronic signature vs digital signature
An electronic signature is any electronic mark of agreement, such as a drawn, typed, or uploaded signature, and that is what iHatePDF creates. A digital signature is a specific kind that uses a certificate from a certification authority to tie the signature to your identity and reveal any later change to the file. Signature requests here end with a Certificate of Completion which, with the verification option on (the default), records the file's SHA-256 fingerprint and a verification code. If a government portal or court asks for a certificate-based signature, such as a Qualified Electronic Signature in the EU, an ICP-Brasil or gov.br signature in Brazil, a DSC or Aadhaar eSign in India, or a qualified signature (UKEP) in Russia, use the certificate and software it names. And if a PDF already carries a digital signature, adding anything to it changes the file and invalidates that signature.
Common signing scenarios
- Freelance contracts. Client agreements, statements of work, NDAs. Use Sign PDF for multi-party signing with the client.
- Employment paperwork. Offer letters, contracts, onboarding forms, expense reports. Use Sign PDF for HR workflows, Editly for quick personal sign-offs.
- Real estate. Lease agreements, rental applications, condo disclosures. Use Sign PDF for the formal lease, Editly for the supporting paperwork.
- Legal documents. Affidavits, declarations, witness statements, settlement agreements. Use Sign PDF for the audit trail.
- Vendor and supplier agreements. Service contracts, purchase orders, terms of service. Use Sign PDF for the formal agreement.
- School and education forms. Permission slips, enrollment forms, internship agreements. Use Editly for quick parent signatures.
- Financial documents. Loan applications, account opening forms, tax filings. Use Sign PDF for binding documents, Editly for supporting forms.
- Medical and consent forms. Patient consent, HIPAA acknowledgments, treatment authorizations. Use whichever fits the workflow.
Tips for clean signatures
- Use a stylus for drawn signatures. A stylus on a tablet produces a far more authentic signature than a mouse or trackpad. Apple Pencil or Surface Pen are ideal.
- Save a signature image for reuse. Sign once on paper, photograph or scan, save as PNG with transparent background. Upload the same image every time for consistency.
- Sign slowly the first time. Your first drawn signature on a screen sets the baseline. Take a few seconds rather than rushing.
- Add a date in your own writing or as text. Most contracts require the signature date, not just the signature itself.
- Verify the document before signing. Read the whole thing. A digital signature is just as binding as ink. Use Editly to make any edits BEFORE signing, not after.
- Password-protect important signed documents. After signing, run through Protect PDF for sensitive contracts.
- Share via secure link. For sensitive signed documents, use share as link with the 35-minute auto-expiry instead of permanent attachments.
Workflow chaining
After signing, chain into other tools in the same session: Compress for email attachment limits, Protect for password security, Merge to combine the signed document with cover letters or exhibits, Split to extract specific signed pages, or use the share button to send the signed file directly via WhatsApp, Gmail, or temporary link.
Privacy and security
Files upload over HTTPS, process on our server, return to you with the signature applied, and delete automatically within one hour. Documents you send for signature are the one exception: they are stored securely until the request expires so every signer can open them. GDPR-compliant. The signed file is yours alone, never accessed by employees, never used for AI training. Safe for legal contracts, financial agreements, medical forms, and other confidential documents. See the privacy and security guide for the full picture.
Frequently asked questions
Is this signature legally binding?
Yes. The ESIGN Act (USA) and eIDAS Regulation (EU) make electronic signatures legally equivalent to handwritten signatures for most contracts, agreements, and consent forms. iHatePDF signatures meet the Simple Electronic Signature (SES) standard under eIDAS and the equivalent under ESIGN, which is sufficient for the vast majority of business and personal use cases including NDAs, employment contracts, leases, vendor agreements, and consent forms.
How do I add a signature to a PDF for free?
Open Sign PDF, upload the file, and create your signature by drawing, typing, or uploading an image of it. Click where it belongs, resize or move it, and download the signed PDF. It is free, adds no watermark, and needs no account.
Can I fill and sign a PDF online?
Yes. Add text anywhere on the page to fill in names, addresses, or blank fields, add the date, and place your signature before downloading. Text can be typed in any language, including Chinese, Arabic, Hindi, and Russian.
Can I sign a PDF without Adobe Acrobat?
Yes. Sign PDF and Editly run in your browser, so there is no software to install, no subscription, and no trial. Signing your own PDFs and sending signature requests are both free.
How do I sign a PDF on my phone or iPhone?
Open Sign PDF in your phone's browser, such as Safari or Chrome, pick the PDF from your files or cloud storage, and draw your signature with your finger. There is no app to install, and the signed PDF downloads straight to your phone.
Which method should I use: Sign PDF or Editly?
Use Sign PDF when the document needs several signers, a signature request by email, an Audit Trail, or a Certificate of Completion. Use Editly when you are also making other edits to the same document. Both let you draw, type, or upload your signature, and Editly also has a pen for freehand marks.
Can I sign multiple pages in a single PDF at once?
Yes. Both tools let you place multiple signatures on different pages. The page navigator on the side lets you jump through the document and add signatures wherever they are needed. Useful for contracts with signature blocks on multiple pages, NDAs with initials per page, or any form requiring signature in several places.
Can I send a PDF to others for them to sign?
Yes, with Sign PDF. Upload your PDF and create a signature request: add up to 20 signers by name and email, place the signing fields, set your security options, and send. Each signer receives an email with a secure link, valid for 1 to 60 days (15 by default), to read and sign the document in their browser. When everyone has signed, you receive the final signed copy with an Audit Trail and a Certificate of Completion. Request documents can be up to 25 MB.
Is the Audit Trail legally accepted?
Yes, in jurisdictions that recognise electronic signatures (ESIGN in the US, eIDAS in the EU, and equivalent regimes elsewhere). The Audit Trail records who signed, the date and time each signature was applied, the IP address, and the device. It is tamper-evident and can be used as evidence in legal proceedings if a signature is ever disputed.
What is the difference between an electronic signature and a digital signature?
An electronic signature is any electronic mark of agreement, such as a drawn, typed, or uploaded signature, and that is what iHatePDF creates. A digital signature uses a certificate from a certification authority to tie the signature to your identity and detect later changes. If a portal requires a certificate-based digital signature, use the certificate and software it names.
Can someone check that a signed PDF has not been changed?
Yes, for documents signed through a signature request. The Certificate of Completion lists every signer, and with the verification option on (the default) it adds the file's SHA-256 fingerprint, a QR code, and a verification code that open a public page confirming the document is authentic.
Can I resize or move my signature after placing it?
Yes, before downloading. Click the placed signature to select it, then drag to reposition or drag the corner handles to resize. After the signed PDF is downloaded, the signature is embedded in the file and cannot be moved or removed without access to the original unsigned version.
Can I add a signature using a stylus or Apple Pencil?
Yes. A stylus produces a far more authentic signature than a mouse or trackpad. Apple Pencil on iPad, Surface Pen on Surface devices, S Pen on Galaxy Tab, and any active stylus on Android tablets all work. For touch screens without a stylus, drawing with your finger also works and looks fine for most purposes.
Can I save my signature and reuse it later?
Yes, while the page is open: a saved signature can be placed again on any page without redrawing it. Signatures are not stored after you close the page, in Sign PDF or in Editly. For consistent signatures across visits, sign once on paper, photograph or scan it, save it as a PNG with a transparent background, and upload that image whenever you need to sign.
Will my signature look the same every time I use it?
Drawn signatures vary slightly each time, similar to handwritten signatures on paper. For perfectly consistent signatures across documents, upload an image of your signature (PNG with transparent background) and reuse the same image file every time. Typed signatures in a signature font are also identical between uses.
Is this PDF sign tool really free?
Yes. Sign PDF is free for files up to 80 MB, with or without an account, and sending a PDF to others for signature is free too (up to 25 MB). Editly is free for files up to 20 MB without an account, 50 MB with a free account. No watermark on output, no trial period requiring a credit card.
Are my files kept private?
Yes. Files upload over HTTPS, process on our server, return to you with the signature applied, and delete automatically within one hour. Documents sent for signature are stored securely until the request expires, so every signer can open them. The signed file is yours alone, never used for AI training or human review. GDPR-compliant. Safe for contracts, financial agreements, and confidential documents. See the privacy and security guide for the full picture.
Can I sign password-protected PDFs?
Yes, but you need the password to open the file first. Once the file is unlocked, signing works normally. If you want the signed file to also be password-protected, re-apply protection with Protect PDF after signing. The combination of password protection plus a signature is the strongest setup for sensitive contracts.
What size files can I add?
Up to 80 MB per file, with or without an account, and up to 25 MB when you send a PDF to others for signature. For files larger than the limit, run through Compress PDF first to bring them under the cap. Compression typically reduces file size by 50-90 percent with no visible quality loss, so even very large scanned documents usually fit comfortably.
How do I sign a PDF that was emailed to me?
Save the attachment, upload it to Sign PDF, sign it, and download the signed PDF to attach to your reply. You can also create a share link for the signed file straight after signing.
Why can't I sign my PDF?
Usually the PDF is password-protected or its security settings block changes. Sign PDF asks for the password when one is needed. If the file is locked against editing and you have the right to change it, remove the protection with Unlock PDF first.
Legally valid under ESIGN and eIDAS. Free, no signup, no watermark.
