Frequently Asked Questions
What causes PDF files to become corrupted?
PDFs can become corrupted during incomplete downloads, abrupt system crashes, improper transfer over network connections, or errors from faulty PDF creation software.
Can this fix PDFs that refuse to open in Adobe Acrobat?
Yes! Most opening errors are caused by broken xref offsets or broken trailer dictionaries, which our dual-engine healing process completely repairs.
Is my repaired PDF uploaded to any server?
No. The entire parsing and repair process takes place directly within your web browser using client-side WebAssembly.
