PDF Repair FAQ

Can all corrupted PDFs be repaired?

Not always. Success depends on the type and severity of corruption. Minor damage (e.g., cross-reference table errors) has a high repair rate, while severely corrupted files may not be fully recoverable.

Will the content be complete after repair?

The system recovers as much content as possible. However, if the original data is severely damaged, some pages or elements may be unrecoverable.

Can I use this on my mobile phone?

Absolutely. Our tool is entirely web-based and compatible with all major browsers. Whether you're on a phone, tablet, or computer, you can process files anywhere.

What are the free plan limits?

Free users can process PDFs up to 100 MB. Upgrade to Pro for larger files.

Is the repair process safe?

Your files are safe. 256-bit encrypted transfer, EU-based servers, GDPR compliant, and permanently deleted after processing.
