Frequently asked questions

What causes PDF corruption?

Common causes: incomplete downloads, disk errors, file system issues, or software crashes during save.

Can all corrupted PDFs be repaired?

Not always. The success rate depends on how much of the original data is intact. Partially corrupt files recover well; completely zeroed files cannot be recovered.

Will all pages be recovered?

The tool recovers as many pages as possible. Pages with severe corruption may be skipped to preserve the rest of the document.

Will images and text be preserved?

Typically yes, if the underlying content streams are intact. The repair only rebuilds the file structure, not content.

What if repair does not work?

If the PDF has DRM or severe corruption, recovery may not be possible with any tool. Contact the original document source.
