How to Scan Documents to PDF Online Free (No App Needed)
Everyone has the drawer. The drawer with receipts you might need for taxes, ID cards you keep meaning to digitise, a contract a lawyer printed for you, business cards from a conference, a handwritten note you should not lose. The drawer because every scanner app wants you to make an account, watch ads, install 80 MB on your phone, and then charges three dollars to remove the watermark.
iHatePDF Scan is a document scanner that runs in any browser. No app, no account, no watermark. On a phone, your camera becomes the scanner directly. On a desktop, a QR code on screen connects your phone in two seconds and your phone becomes the scanner for the desktop session. Edges are auto-detected, perspective is corrected, the result is a clean PDF. This guide covers all three workflows and what to do with the scan afterwards.
On phone: Open Scan → allow camera → point at document → capture → download PDF
On desktop: Open Scan → scan the on-screen QR with your phone → phone becomes the camera → download PDF on desktop
Existing photo: Add the image file and it becomes a page in your PDF
How to scan a document to PDF online for free
- On your phone: open the Scan tool and point your camera at the document, ID card, or bank card you want to scan.
- On desktop: scan the on-screen QR code with your phone. Your phone connects instantly and becomes the scanner for that desktop session.
- Capture the page. The tool auto-detects the edges, straightens the perspective, and cleans up the image automatically.
- Repeat to add more pages. You can also drop existing PDFs or images from your device between scans to mix into the final file. All pages appear together, ready to combine into a single PDF.
- Download the final PDF. On your phone, you can also download it as an editable Word document. For a next step, open the PDF in Sign, OCR, or Compress.
Why scan in your browser instead of using an app
- No install. Scanner apps like CamScanner and Adobe Scan want 80-150 MB of storage and an account. iHatePDF Scan is a webpage. Open it, scan, done.
- No watermark. CamScanner's free tier puts a "Scanned by CamScanner" banner on every page. Adobe Scan needs an account and pushes you into the paid Document Cloud. iHatePDF produces clean PDFs with no watermarks on either tier.
- The desktop QR bridge is unique. No native phone scanner can do this. Open Scan on your laptop, point your phone at the QR, capture pages from your phone, download the PDF on your laptop. The pages move from phone to laptop in real time.
- Every next step in one place. Download the scan, then make it searchable with OCR, sign it with Sign PDF, compress it, or convert it to Word, all free on the same site.
- Mix scans with existing files. Drop a PDF invoice from your device between two scanned receipts. Drop an image of a contract page between scans of handwritten notes. The final PDF combines them all in the order you arrange. Most scanner apps make you do this in a separate merge step.
- Privacy. Pages sent to your desktop are deleted once your PDF is created, or about two hours after the last page. No cloud storage of your sensitive paperwork. See the privacy guide.
- Cross-platform. Built-in scanners are locked to platforms: Apple Notes scanner only on iPhone, Google Drive scanner only on Android. Browser scanning works on every device.
The desktop QR bridge, explained
This is the feature most users do not realise exists, and it is the killer reason to use a browser scanner over a phone app. Here is exactly what happens:
- You open Scan on your laptop or desktop browser.
- The page shows a QR code linked to a temporary, unique session.
- You open the camera app on your phone and point it at the QR code. A link appears.
- You tap the link. Your phone is now connected as a remote camera for the desktop session, no app installed, just a browser tab on the phone.
- You capture pages with the phone (where the camera quality is usually much better than a laptop webcam, and the form factor is ideal for shooting flat documents on a table).
- Each captured page appears instantly in the desktop browser session.
- When you are done, the PDF assembles on the desktop. The phone session ends automatically.
The result is the convenience of phone camera quality with the productivity of being in front of your real screen. Useful for scanning a stack of receipts at your desk, a multi-page contract, a small notebook of handwritten notes, or anything where you need the file ready to use on your computer immediately.

After scanning: workflow chaining
The scan is rarely the end of the workflow. Common patterns:
- Scan, then OCR. The raw scan is an image. OCR PDF adds a searchable text layer so you can copy text from receipts, search through contracts, and quote from book chapters. For converting the OCR result into an editable Word file, see the scanned PDF to Word guide.
- Scan, then sign. Paper contract arrived in the mail. Scan it, open it in Sign PDF, sign, send back. The print-sign-scan loop becomes scan-and-sign. See the sign PDF guide.
- Scan, then compress. Multi-page scans can hit 10-50 MB depending on resolution. Compress PDF shrinks them by 50-90 percent before email or upload.
- Scan, then protect. For IDs, financial documents, or anything sensitive, run through Protect PDF with a password before sharing.
- Scan, then merge. Scan a multi-day stack in batches, then Merge PDF the results into one organised file.
- Scan, then edit. Use Editly to highlight, redact, or annotate the scan.
Tips for clean scans
- Use a contrasting background. White paper on a dark wood table, or dark paper on a white desk. The edge detection works far better with high contrast between document and surface.
- Even, indirect lighting. Avoid harsh direct sunlight (creates shadows) and overhead spotlights (creates glare). A diffused light source like a window with curtain or an evenly lit room is ideal.
- Hold the camera parallel to the document. The perspective correction handles small angles, but a 45-degree tilt produces a stretched corner. Stay roughly overhead.
- Fill the frame. The document should occupy most of the camera view. Too far away wastes resolution, too close cuts off corners.
- Steady hands or a surface. Rest your elbows on the table or use a phone stand for sharp captures. Motion blur ruins detail and confuses OCR.
- One page at a time. Capturing two facing pages at once works for books, but the perspective correction may not be perfect. For best results, scan one page at a time and combine afterwards.
- Flatten curled paper. A book or thick stack tends to curl at the edges. Press flat with a hand or another book just outside the frame.

Frequently asked questions
Do I need to install an app to scan documents to PDF?
No. iHatePDF Scan runs entirely in your browser. On phone, the browser uses your camera directly. On desktop, you scan a QR code with your phone and your phone becomes the camera, sending the scans back to your desktop browser in real time. No app downloads, no account, no installs.
Can I scan multi-page documents into one PDF?
Yes. Capture as many pages as you need in a single session. Each scan appears in a tray, and when you are done, all scans are combined into a single PDF in the order you captured them. You can also drop existing PDFs or images from your device between captured pages to build a mixed file.
How does the desktop QR code method work?
Open Scan on your desktop. The page displays a QR code linked to a temporary session. Open the camera on your phone, point it at the QR code, tap the link that appears. Your phone is now connected as a remote camera for that desktop session. Capture pages on the phone, see them appear instantly on the desktop. When done, the PDF is ready on the desktop for download. The session ends automatically after the scan is complete.
Can I scan IDs, passports, or bank cards?
Yes. Cards mode captures the front and back of an ID card, driver's license or bank card and places both sides on one A4 page, ready to print or upload. For a passport or a larger document, use the normal Scan mode. For sensitive documents, consider passing the scan through Protect PDF afterwards to add a password before sharing.
Is it safe to scan sensitive documents online?
Yes. Pages travel over HTTPS. Pages sent from your phone to your desktop are deleted as soon as your PDF is created, or automatically about two hours after the last page if you do not finish. No human review, no AI training, no permanent storage. GDPR-compliant. For extra security, password-protect the scan with Protect PDF before sharing.
Can I scan from an existing photo instead of using the camera?
Yes. If you already have a photo of a document (from your camera roll, received over WhatsApp, or any other image), add it as a page: on a computer with Add file, where it is placed on an A4 page, or on a phone from your gallery. Saved photos are added as they are, so for the cleanest result photograph the paper with the Scan camera, where cropping straightens the page and filters sharpen the text.
Does this work on iPhone and Android?
Yes. Any modern mobile browser (Safari on iPhone, Chrome on Android, Firefox, Edge, Brave) supports the camera access needed for scanning. The desktop QR bridge works whether your phone is iPhone, Android, or anything else with a browser.
How do I scan a document and send it by email?
Scan the pages and download the PDF, then attach it to an email or send it in a messaging app such as WhatsApp, from your phone or computer. On a phone, you can also open the downloaded file and tap the share button. If the PDF is too large to attach, shrink it with Compress PDF first.
Are there limits when adding existing files between scans?
You can mix JPG, PNG, HEIC and PDF files into your scan, with no account needed and no account tiers. A phone-to-desktop session holds up to 60 pages; when you scan on your phone alone, every page you capture goes into one PDF.
Can I make the scanned PDF searchable (OCR)?
Yes. After scanning, run the PDF through OCR PDF to convert the images to selectable, searchable, and copyable text. The original layout is preserved while a text layer is added underneath the images. Useful for receipts, contracts, and any document you want to search through later.
Will my scans be high quality?
Yes, with good capture conditions. The tool auto-detects document edges, straightens the perspective (so a photo taken at an angle becomes a flat rectangle), and cleans up shadows and uneven lighting. For best quality, capture on a contrasting background (white paper on a dark surface or vice versa), with even lighting, and the document filling most of the frame.
Can I edit, sign, or compress the scanned PDF afterwards?
Yes. Download the scan, then open it in Sign PDF to add a signature, OCR PDF to make it searchable, Compress PDF to shrink it, Editly to add text or highlights, or PDF to Word to convert the text to an editable document. On a phone, you can also choose Download as Word right after scanning. All free, no account needed.
What is the difference between iHatePDF Scan and Apple's or Google's built-in scanner?
Apple Notes (iOS) and Google Drive (Android) have built-in scanners that work well for personal use but are locked to their platform. iHatePDF Scan works in any browser on any device, and the desktop-to-phone QR bridge lets you capture from your phone and immediately use the result on your desktop, which built-in scanners do not offer. Once downloaded, the scan can go into 25+ other free PDF tools in the same browser.
Browser-based, no app install, no watermark. Phone, desktop QR, or upload.
