1 Your damaged PDF
2 What it does
- Reads the file with qpdf and writes it again, whole and tidy.
- If that fails, rebuilds the file’s structure from the parts still in it, and recovers the pages of a file that was cut short.
- If nothing else works, saves the pages that can still be drawn as pictures.

How to repair a damaged PDF
- Choose the PDF that will not open, shows an error, or opens with pages missing (or drop it on the box). The repair starts at once. A locked PDF asks for its password.
- The result says what was wrong, in plain words, and how many pages came back. Every page is shown small, so you can check them.
- Download or share the repaired PDF.
Everything happens in your browser: the PDF is never uploaded to ap7am or anywhere else. The new file keeps
your PDF’s name, such as marksheet-repaired.pdf.
Three ways, the best first
- Rewritten by qpdf. A file qpdf can read is written again, whole and tidy, with its text, fonts and pictures as they were. A file with nothing wrong comes back as a clean copy, and the page says no damage was found.
- Its structure rebuilt. Every PDF has a table at its end that says where each part of the file starts (the cross-reference table). When that table is wrong or missing, a part has the wrong length, or the file was cut short while downloading, the parts are read one by one from the start of the file, the table is made again, and the pages are put back together, text and all. If the list of pages itself was lost, the pages are found one by one and put in the order they are stored.
- Pages as pictures. When neither works, every page that can still be drawn is saved as a picture in a new PDF. The pages look the same, but their text can no longer be selected or searched, and the page says so plainly.
What it cannot do
A part of a file that is missing (the end of a download that stopped halfway) cannot be brought back: the pages in it are left out, and the result says how many pages the file said it had and how many were found. Download the file again if you can. A page whose own contents are damaged may come back incomplete: check every page before you use it.
Questions
My PDF opens on the computer but a portal says it is damaged or invalid.
Try it here: a clean rewrite often fixes what strict portals refuse. If it is too large for the form, then use Compress PDF.
The PDF from WhatsApp or email will not open.
It may have been cut short while downloading. Repair recovers the pages that arrived; downloading it again may give you all of them.
My PDF is locked with a password.
Type its password when asked: it stays on your device, and the repaired PDF keeps the same password. To take the password off, use Unlock PDF.
What does “What qpdf said” mean?
Those are the messages of qpdf, the PDF tool that does the repair, as it wrote them. The lines above them say the same in plain words.
Is my PDF uploaded or stored?
No. It is repaired in your browser; nothing is sent to ap7am or anywhere else.
Made with qpdf (Apache 2.0 licence), compiled to WebAssembly, pdf-lib (MIT licence) and Mozilla’s pdf.js (Apache 2.0 licence), all running in your browser. Licences.
