About Repair PDF

Fix PDFs that won't open.

Repair PDF targets one specific, common failure: a PDF that won't open because its cross-reference table or trailer is broken or missing, often from an interrupted download or a bad export. Sable rebuilds that structure so the file opens again. It can't restore content that's actually missing or corrupted — a truncated file, or a stream with damaged bytes — because no tool can reconstruct data that isn't there anymore.

Why Repair PDF

Built for people who care about their documents.

Fixes the #1 'won't open' cause

A broken or missing cross-reference table is the most common reason a PDF suddenly fails to open.

Two independent recovery passes

Tries a structural rebuild first, then a second, more tolerant parser if the first doesn't produce a valid file.

Runs on your device

Nothing uploads to a server — repair happens entirely in your browser.

Honest failure

If the file is too damaged to recover, you get a clear error, never a silently broken or blank result.

Privacy & Security

Your documents belong to you.

Sable is designed around a single principle: your files are yours. We never train on them, never sell them, and never keep them longer than we need to.
