Common questions
What kinds of damage can it fix?+
It rebuilds PDFs with a broken cross-reference table, corrupted object structure, or a truncated/incomplete download. The most common reasons a PDF "won't open". It can't recover content that simply isn't in the file.
Is every PDF recoverable?+
No. If a file is severely damaged or the data is genuinely missing, no tool can bring it back. We try qpdf first and fall back to a Ghostscript rewrite to recover as much as possible, but some files are beyond repair.
Is my file private?+
Yes. It's uploaded over an encrypted connection to our private storage (Supabase, named in our privacy policy), repaired on our own server, never by an outside conversion service, and the upload and result are deleted after 1 hour.
Will it change my content?+
It rebuilds the file's internal structure, not your pages. Text and images are preserved where they're recoverable; the goal is a valid PDF that opens.
Is there a limit?+
No watermark and no signup. Free covers 10 server conversions a day, up to 100 MB a file. Pro removes the daily limit and raises the file limit to 2 GB.
