Fix Corrupted PDF: what you need to know
Interrupted downloads, faulty email attachments and crashing apps can damage a PDF's internal index, so viewers refuse to open it. FilesForU rebuilds the file's structure and saves every page it can recover into a fresh, valid PDF.
Files that are only partly downloaded may be missing pages that can't be recovered — if the original source is available, downloading it again is the best fix.

Questions & answers
Can every PDF be repaired?
Most structural damage can be fixed. If parts of the file are missing, those pages can't be brought back.
Will repairing change my content?
No. The pages are rebuilt into a clean file; content stays the same.
Is it safe for confidential files?
Yes. Repair runs on your device and the file is never uploaded.
Are my files uploaded to your server?
No. This tool runs entirely inside your browser, so your files stay on your device. FilesForU never receives, stores or sees them.
Is it really free?
Yes. Every tool is free with a free account — no daily limit, no watermarks, and files up to 500 MB.
