Expert tips for successful PDF repair
Use the original file
Always upload the earliest available copy of your corrupted PDF, as backups typically have less damage than edited versions.
Don't modify before repair
Avoid opening and resaving the damaged file in other applications before repair, as this can worsen the corruption.
Test different repair modes
Try both automatic and deep repair options — deep mode uses more aggressive reconstruction techniques for severely damaged files.
Focus on content recovery
If full document repair isn't possible, image extraction may still recover valuable visual content from the corrupted file.
Preserve the original
Keep your corrupted file until you've verified the repair was successful and contains all the content you need.
Thoroughly verify results
Carefully review the repaired PDF to ensure all pages, images, and text content were properly restored.
