Frequently asked questions
What can Repair PDF fix?
It re-writes the file structure, which resolves many 'damaged' or 'cannot open' errors caused by malformed metadata or cross-reference tables.
Can it recover a totally corrupted file?
It can't rescue data that's truly lost, but it cleanly rebuilds anything that's still readable, which fixes the most common issues.
Are my files uploaded to a server?
No. Slate processes your PDF entirely in your browser. Your files never leave your device, which is faster and far more private than typical online tools.
Is Repair PDF really free?
Yes. Repair PDF is completely free with no signup and no limits. Slate is funded by unobtrusive ads, not subscriptions.
