How to destroy a PDF
1
Upload your PDF or PDFs from your device, or pull them from Google Drive, Dropbox, or OneDrive. Nothing is uploaded to a server - the whole tool runs inside your browser.
2
Pick a destruction method in the options panel: Shred turns pages into shredded paper strips, Blackout makes them solid black, and Blank leaves them completely empty. The page previews show exactly what the result will look like.
3
By default the whole document is destroyed. To destroy only some pages, click them in the workspace or type a page range like 3-7, 12 - the remaining pages are kept unchanged. Optionally stamp DESTROYED across destroyed pages or add a certificate of destruction page.
4
Click Destroy PDF. The output is rebuilt from scratch, so destroyed pages contain nothing from the original and can never be recovered. Download it, save it to the cloud, or send it into another tool.
Why use our Destroy PDF tool
Truly irreversible
The output file is built from scratch: destroyed pages carry no text, images, fonts, hidden layers or metadata from the original, so the content cannot be recovered by any means.
Three destruction methods
Shred replaces pages with a shredded-strip pattern, Blackout with solid black pages, and Blank with completely empty pages - pick whichever fits the occasion.
Destroy all or selected pages
One click destroys the whole document, or click pages (or type a range like 3-7, 12) to destroy only those and keep the rest untouched.
DESTROYED stamp
Optionally stamp DESTROYED diagonally across each destroyed page, so anyone opening the file knows at a glance that the content was removed on purpose.
Certificate of destruction
Optionally prepend a certificate page recording the document name, how many pages were destroyed, the method, and the date.
100% in your browser
Files never leave your device - destruction happens locally with no upload, so even we never see the document you are destroying.
Metadata wiped
Title, author, subject, and keywords are cleared in the output, so document properties leak nothing about the original.
Visual page preview
Thumbnails preview the destruction live - switch methods and the overlay updates, so you always see exactly what you will download.
Batch processing
With a free account, destroy up to 3 PDFs at once (80 MB each, 120 MB total). Each gets its own output file. Single-file destruction needs no signup, up to 80 MB.
Free, no watermark
No watermark, no signup needed for single jobs, no per-day cap. Your original file on your device is never modified.
Frequently asked questions
PDF 元数据怎么删除？
在上方添加 PDF，选择 Metadata Scrubber，下载清理后的副本即可。标题、作者、主题、关键词、创建程序和生成程序、自定义字段、XMP 元数据、程序私有数据和文档 ID 都会被清除，日期也会重置。
PDF 元数据怎么修改？

怎么查看 PDF 的元数据？
在 PDF 对比 中添加文件，文档概览会列出版本、标题、作者、创建和修改日期等属性。
怎么防止别人复制 PDF 里的文字？
选择 Lockdown，每页都会转成图片，文字无法再被选中、复制、搜索或提取。页面看起来不变，但文件可能变大，也无法再搜索文字。
能在 PDF 里隐藏秘密信息吗？
可以。Ghostwriter 会把信息藏在文件里，不改变页面外观；可以加密码加密，也可以不加密，任何人在这里检查文件都能读出。之后用同一工具即可显示隐藏的信息。
文件会上传到服务器吗？
不会。八个工具都完全在浏览器中运行，PDF 不会离开你的设备。只有你选择解锁的加密文件，会在解锁这一步经过我们的服务器。
会修改我的原文件吗？
不会。每个工具都会生成新的副本供下载，原始 PDF 保持不变。
可以批量处理多个 PDF 吗？
免费账户一次最多 3 个 PDF（总计 80 MB），结果打包成一个 ZIP 下载。
