Frequently Asked Questions
Is Repair PDF free to use?
Yes, absolutely! Every single tool here is completely free. There are no limits, no hidden subscription costs, and you don't even have to sign up or share your email address. Just use it as much as you need.
Is it safe to repair pdf online?
Yes, it is 100% safe. Most online PDF tools copy your files to their servers, but we don't. We use a browser-based technology called WebAssembly to do all the heavy lifting locally on your own computer. Your files never leave your device.
What file size can I process?
Because the tools process your files directly on your computer, we don't impose any file size limits at all. The only limit is what your computer or phone can handle, meaning you can easily edit files that are 100MB or larger.
Do I need to install any software?
No, you don't need to download or install anything. All you need is a standard web browser (like Chrome, Safari, or Firefox). Just load this page, drag in your file, and you're good to go.
