Frequently Asked Questions
What kinds of PDF problems can this fix?
It works well on files with structural issues, like a broken cross-reference table or index, that stop some viewers from opening the file correctly.
Can it recover any corrupted PDF?
No. If the file is too damaged for our engine to open at all, it cannot be repaired this way. Try a different copy of the file if you have one, or a dedicated file recovery tool.
Will repairing the file change its content?
No. The content stays the same. What changes is the file's internal structure, which is rewritten cleanly.
Can I repair multiple PDFs at once?
Yes. Upload several files and each one that's successfully repaired is returned together in a single zip download.
What happens if my file can't be repaired?
You'll see a message telling you the repair was unsuccessful, rather than a broken file being returned to you.
Is it safe to upload confidential documents?
Yes. All uploads happen over an encrypted connection, and both the source file and the repaired PDF are automatically deleted from our servers after processing.
Is repairing a PDF really free?
Yes. There is no cost, no subscription, and no account required.
Can I use this on my phone?
Yes, the tool is fully responsive and works in any modern mobile browser on iOS and Android.
