What kinds of problems can this fix?

It helps when the PDF structure is inconsistent—often after an interrupted download, a bad save, or a truncated transfer. It cannot recover missing content that was never in the file.

Will the layout or quality change?

A full rewrite can slightly change how some viewers render complex graphics or embedded fonts. Text-based documents usually look the same; heavy design files deserve a quick visual check after download.

Do you support password-protected PDFs?

No. If the file is encrypted, remove the password in a trusted desktop app first, then try again here.

Can every broken PDF be fixed?

No. Some files are too incomplete or use features we cannot rebuild. If recovery fails, try a trusted backup or export again from the original application.
