FAQ

What issues can be fixed?
Broken xref tables, minor structural errors, and non-critical metadata issues. Severe corruption may not be fully recoverable.
What is linearization?
Linearization rearranges the PDF for faster incremental loading in web browsers (a.k.a. Fast Web View).
Will fonts and images be preserved?
Yes, the tool aims to preserve all content. In rare cases, some non-essential elements may be normalized.
Is there a file size limit?
Server-side limits apply (your server is configured for large uploads). If you hit a limit, contact the server admin.
