❓ Frequently Asked Questions

Can every broken PDF be repaired?

No. If the file is severely truncated or its page data is missing, no repair tool can reconstruct information that is no longer present.

Which mode should I use?

Try Standard first. Use Deep when the repaired file still has rendering or structure problems.

Does repair change quality?

Standard mode generally preserves content. Deep mode can reinterpret PDF objects and may change some advanced features.
