Why pick Convertify for this?
Files stay on device
Convertify processes everything in your browser using JavaScript. Your file is never uploaded — confirm with DevTools → Network. That makes this safe for sensitive material like contracts, IDs, and financial documents.
No upload wait
Because nothing uploads, processing starts the instant you click. For typical files (under 50 MB) the whole job finishes in seconds — no progress bar, no queueing behind other users.
No daily quota
Free without limits, including no "3 conversions per day" cap that competing services impose. Run as many repair pdf jobs as you need.
No watermark
Your output is clean — no Convertify branding, no metadata stamp. Same as if you'd run a paid desktop app.

Frequently asked questions
Why won't my PDF open?⌄
PDFs can become corrupted from interrupted downloads, failed transfers, or storage errors. Repair attempts to rebuild the file structure so it opens again.
How do I repair a corrupted PDF?⌄
Upload the damaged file and the tool tries to reconstruct its internal structure, then provides a recovered version to download.
Can every corrupted PDF be recovered?⌄
Not always. Lightly damaged files often recover fully, but severely corrupted or truncated files may only recover partially.
Will repair recover all my content?⌄
It recovers as much intact content as possible. Pages that were destroyed in the corruption may not be retrievable.
Is repair private?⌄
Yes. The process runs in your browser, so your file is never uploaded.
