📋 Other Methods to Try If PDF Repair Fails

If the online tool doesn’t fix your PDF, try these alternatives:

1. Open PDF in a Different Reader
   Some files fail in one PDF reader but open in another (like Adobe Reader vs. Foxit PDF).
2. Restore From Backup
   If you use cloud storage (Google Drive, Dropbox), check previous versions of the file.
3. Convert to Another Format and Back
   Use a PDF to Word converter, then re-export it as PDF. Sometimes this regenerates file structure.
4. Use Adobe Acrobat’s Built-in Repair Feature
   Acrobat Pro may attempt to recover damaged files automatically.
