More free PDF tools
Same quality bar. Still free. Still no upload.
Your files never leave your device
Free to use, with no account, no usage limit and no watermark, because the work runs on your device rather than on our servers.
This is not a promise about how carefully we handle your upload. There is no upload. The file you choose is read into memory by your own browser, processed there, and handed back as a download — the tool has no server component and makes no network request with your data.
- Nothing is stored. We never receive the file, so there is no copy to retain, no retention period to disclose, and nothing to delete on request.
- Nothing is transmitted. No upload endpoint, no analytics payload carrying file contents, no third-party processor.
- You can verify it. Load this page, disconnect from the internet, and use the tool. It still works, because everything it needs is already on your machine.
- Nothing persists after you close the tab. Files are held in page memory only — not in local storage, not in a cache, not in a database.
A note on wording, because it matters: we do not describe these tools as “encrypted.” Encryption protects data that travels to somebody else's computer. Your file does not travel, so there is nothing to encrypt and nothing to intercept — which is a stronger guarantee than encryption, not a weaker one. The page itself is served over HTTPS like the rest of the site.
This makes the tools safe for material you are contractually barred from uploading to third-party services — client footage under NDA, unreleased campaign assets, anything covered by a confidentiality clause.
How it works
1. Drop the broken PDF
It is parsed in your browser, skipping damage where it can.
2. Rebuild
The objects it could read are written into a fresh file with a new cross-reference table.
3. Download the -rebuilt PDF
Open it in your viewer and check each page.
Questions
Will this recover a blank or garbled page?
No. If the content stream on that page is already damaged, rewriting the xref cannot invent the missing operators. This tool fixes the container, not the drawing instructions inside a page. A file that will not open at all is in range; a file that opens with a black page is not.
Is the output byte-for-byte the same as the input?
No, and it should not be. Incremental updates are folded in, object numbers may change, and unused objects can be dropped. The pages you can already see should look the same; the bytes will not match a hash of the original, which is the point of a rebuild.
What kind of damage can it fix?
Structural problems such as a broken cross-reference table or messy incremental saves that confuse a viewer. The file is parsed, unreadable objects are skipped, and everything else is written out fresh. It cannot rebuild page content that is already lost.

These rearrange files. Versely makes new ones.
Everything on this page works on a file you already have, which is why it costs nothing. Generating something that did not exist (video from a prompt, a voice, a score) runs a model, and that costs credits.
