Frequently asked questions

How do I repair a corrupted PDF for free?

Upload your damaged PDF using the file selector above and our repair engine will attempt to rebuild its structure and recover the content. Then download the fixed file. No software installation required.

Why won't my PDF open?

PDFs most often become unreadable due to interrupted downloads, incomplete saves, storage errors, or transfer problems. These damage the file's internal structure, which our repair tool attempts to reconstruct.

Can every damaged PDF be repaired?

Most structural damage can be fixed, and even partially corrupted files can often be recovered. However, if the file's content data is completely destroyed, recovery may not be possible.

Is it safe to upload a broken PDF for repair?

Yes. All transfers use 256-bit SSL encryption, and uploaded files are automatically deleted from our servers shortly after processing. Your documents are never shared with third parties.
