About OnlinePDF

OnlinePDF is a collection of free PDF tools that run entirely in your browser. There is no server processing your files — everything happens locally on your device using JavaScript and WebAssembly.

We built OnlinePDF because we believe your documents are private by default. Uploading sensitive files to third-party services is a risk you should not have to take for routine PDF tasks.

How it works

When you use a tool on OnlinePDF, your file is read by your browser and processed in memory using open-source libraries compiled to WebAssembly. The result is offered as a download. At no point does any byte of your file leave your device.

Free, no account required

Every tool is free to use. No sign-up, no email address, no account. We run ads to keep the service free and the cost of hosting near zero (since we do no server-side processing).
