常见问题
What can be repaired?
Broken or missing internal indexes, wrong object offsets and truncated endings are rebuilt. Pages whose data is still in the file come back.
What cannot be repaired?
Data that is really missing (for example a download that stopped halfway) cannot be invented. Files that are not PDFs, or encrypted files, are rejected. If the damage is in compressed object streams, the rebuild may fail and you see an error.
Is the file uploaded?
No. The repair runs inside your browser on your device.
