Frequently asked questions

What can be repaired?

Files with a damaged structure, broken cross-reference tables or minor corruption can often be recovered. Content that is genuinely missing cannot be recreated.

What does “fast web view” do?

It reorders the file so it can start displaying before it has fully downloaded - handy for PDFs opened online.

Is this tool free?

Yes - it is completely free, with no account, no limits, and no watermarks added to your files. Every PDF tool on File-Extension works the same way.
