Frequently asked questions
What kind of damage can be fixed?
Broken cross-reference tables, truncated endings, wrong object offsets and similar structural faults, which cause most “file is damaged” messages. Missing data from a half-finished download cannot be invented back.
Will I keep selectable text?
With Rebuild, yes. Re-render produces page images, so text is no longer selectable but the file always opens.
Are my files uploaded anywhere?
No. The whole tool runs inside your browser using JavaScript. Your files stay on your device, nothing is sent to a server, and nothing is stored. You can even use it offline once the page has loaded.
Is it really free?
Yes. There is no account, no watermark, no file-size tier and no daily limit. Use it as often as you need.
