Repair a damaged PDF online, free

A PDF that refuses to open, opens with an error or shows blank pages has usually lost its internal index — the table that tells a reader where each page and font is stored. It happens with an interrupted download, an attachment damaged by an e-mail system, or a program that saved the file badly. PDF Vision repairs it in two steps. First it rebuilds that index by reading the file from end to end, without touching the content: text, fonts, form fields and links stay as they are. If that is not enough, the document is rewritten page by page from whatever can still be read — the pages come back, interactive form fields and signatures do not. A repair can only recover what is in the file: when part of the content was never downloaded, the pages it held cannot be rebuilt, and when nothing readable remains we tell you so instead of handing back blank pages. Repair runs on PDF Vision's servers, files up to 15 MB, first repair of the day free without an account.

How to repair a damaged PDF

  1. Upload the damaged PDF

    Drag the file onto the upload area, or click to browse. Up to 15 MB.

  2. Repair

    The file’s index is rebuilt; if needed, the document is rewritten from every readable page.

  3. Download the repaired PDF

    Check the preview and save it. Your first repair of the day needs no account.

Why use it

Content untouched first

The first pass only rebuilds the file’s structure: text, fonts and forms are kept exactly.

A second chance

When the structure is beyond repair, every readable page is recovered into a new file.

An honest answer

If nothing can be recovered, you are told — no blank pages passed off as a repair.

Frequently asked questions

Which PDFs can be repaired?
Files with a broken internal index or damaged structure — the most common failures after an interrupted download or a bad e-mail attachment. Most of them come back complete.
Can every damaged PDF be saved?
No. A repair recovers what is in the file. If part of the file is missing, the pages stored in that part are lost; if nothing readable remains, the repair says so.
Will my form fields and signatures survive?
Yes when the first pass is enough, since the content is not rewritten. If the document has to be rewritten, the pages are kept but interactive fields and signatures are not.
Does repair remove a password?
No. A PDF that needs a password to open must be unlocked with that password first, with Unlock PDF.
Is my file uploaded?
Yes, the repair runs on PDF Vision's servers, so the file is uploaded to be processed. Files up to 15 MB.
Is it free?
One free repair a day with no account. A free account raises the daily allowance.
