100% browser-based
Every tool on OhMyPDF runs inside the browser tab you already have open. We use pdf-lib for editing PDFs and pdfjs-dist for rendering. There is no backend, no queue, and no upload progress bar.

No upload, no signup
You don't create an account, you don't get rate-limited, and you never wait in line behind other users. Open a tool, drop a file, get the result. The whole thing works offline once the page is loaded.
Privacy by design
Your PDFs never leave your device. You can disconnect from the network after the page loads and the tools still work — proof that no part of your file is being sent anywhere. Open the browser's network tab to verify.
