Frequently asked questions
What problems can be fixed?
Files cut off during download, with a broken index or structural errors that make PDF readers hang. The tool tries to rebuild the file; if the structure is too damaged, it redraws the pages as images (the text is no longer selectable).
Does it always work?
No. If parts of the content were lost or the file is badly damaged, it can't be recovered. In that case, the tool tells you.
Is it really free?
Yes, 100% free. No sign-up, no subscription and no usage limits. All Tools123 are free.
