What is Repair PDF and how does it work?

Repair PDF is a free online tool from HuntPDF. Repair corrupted PDFs, recover damaged pages, fix cross-references, repair fonts, optimize structure, and linearize for fast web viewing. You upload a file, the work happens on our servers, and you download the result. There is nothing to install and no account to create.

How do I use Repair PDF online?

Upload your file using the box above — drag it in, browse for it, or bring it in from your cloud storage. A preview appears so you can check you've picked the right file. Run Repair PDF, then download the result. You can rename it before you save it.

Is my file secure when I use Repair PDF?

Yes. The file you send to Repair PDF travels over an encrypted HTTPS connection and is processed automatically on our servers. It is never made public, never shared with anyone, and nobody reads it.

Does HuntPDF store my files after Repair PDF has run?

No. Your upload is deleted the moment Repair PDF finishes with it, and the file it produces is removed as soon as you have downloaded it, or when you upload another file, or when you close the page. Nothing is kept, and nothing is used to train anything.

Will the original quality and formatting be maintained?

Yes. Repair PDF is built to leave your content exactly as it is — only the change you asked for is applied. Nothing else about the file is altered or re-compressed.

Can I use Repair PDF on mobile?

Yes. Repair PDF works in any modern browser on phones and tablets — iPhone, iPad or Android — with nothing to install. You can upload straight from your device or from your cloud storage.

Can I rename my file before downloading it from Repair PDF?

Yes. The file Repair PDF gives you back keeps the name of the file you uploaded by default. If you'd rather call it something else, edit the name in the field next to the download button before you save it.

Do I need to install any software to use Repair PDF?

No. There is nothing to download, install or sign up for — Repair PDF is used from your browser and does the work on our servers, so it behaves the same on Windows, macOS, Linux, Android and iOS.

How long does Repair PDF take?

Most files are finished in a few seconds. A large or page-heavy file takes a little longer, because Repair PDF runs on our servers rather than on your device — but you won't be waiting around. You can upload files up to 250MB.

Is Repair PDF free to use?

Yes. Repair PDF is free, with no signup, no watermark on the result and no daily limit for normal use.
