Repair PDF Files Online
免费Repair PDF files online to fix corruption, flatten forms, and make scanned PDFs searchable with OCR. Works on mobile, private by design.
Fix the PDF issues that block you
Corrupted structure
Rebuild broken cross-reference tables (the PDF's internal index) and objects so damaged PDFs open again.
Broken fonts & rendering
Flatten pages or rebuild them as images to bypass missing fonts and display glitches, keeping layouts readable everywhere.
Interactive forms
Flatten form fields into static content so they print the same everywhere, avoiding blanks on shared copies.
Scanned documents
Run OCR to add a searchable text layer to scans and photographed pages, letting you copy and find text like a digital document.
Offline-first fixes
Repair right in your browser; only upload when a server-side rebuild is required, keeping sensitive files on your device whenever possible.
Why choose PDF Juggler for repairs
Compare our local-first repair workflow with the tradeoffs you see on upload-focused fixers.
Offline-first recovery
- PDF Juggler
- Kick off fixes locally so damaged files stay on-device until you explicitly opt into a secure upload.
- Typical online repair tools
- Most repairers make you upload corrupted PDFs, leaving private files on third-party servers while they process.
Advanced clean-up toggles
- PDF Juggler
- Mix and match re-save, flatten, OCR, and image rebuild passes so you can target the exact corruption you see.
- Typical online repair tools
- Presets hide or limit pass controls, so you have to re-upload repeatedly to try different clean-up options.
Seamless convert handoff
- PDF Juggler
- Jump straight into the Convert tool when you need to rebuild pages as images or switch formats—no re-upload required.
- Typical online repair tools
- Hand-offs require downloading and opening a separate converter before you can rebuild damaged pages.
Preserve layout fidelity
- PDF Juggler
- Preview repair settings before export and keep typography, bookmarks, and page order intact wherever possible.
- Typical online repair tools
- Many services rasterize pages or drop bookmarks, so repaired exports lose layout fidelity.
Fix corrupted layouts, flattened forms, and scanned archives without handing files to third-party servers.

常见问题
能修复损坏的PDF吗？
会重新保存并重建PDF，可扁平化表单，或将页面重建为图像以绕过损坏字体。启用OCR可从扫描件恢复可搜索文本。
能让扫描PDF可搜索吗？
可以。启用OCR后，工具会识别页面文本并嵌入不可见的文本层。
扁平化会移除表单交互吗？
会。扁平化将表单字段转换为静态页面内容以保证一致呈现。
我的文件是私人的吗？
可能的情况下修复在浏览器中运行；上传用于服务器修复的文件会被丢弃且不会存储。

修复大PDF需要多久？
