Your file stays on your device
Most free PDF sites upload your file, process it on their servers, and send it back. DocZap loads its code into your browser once, then reads and rebuilds your file in your own device's memory. You can switch off your Wi-Fi after the page loads and the tools keep working.

Frequently asked questions
What is DocZap?+
DocZap is a free collection of 31 PDF and image tools — merge, split, compress, sign, redact, convert, and more — that all run entirely inside your web browser instead of on a remote server.
Is DocZap really free?+
Yes, completely. There's no premium tier, no usage cap, and no watermark added to your files. Running everything client-side means there's no per-file server cost pushing us toward a paywall.
Do I need to create an account?+
No. There are no accounts, logins, or saved files. Open a tool, process your file, and download the result — nothing about you or your document is stored anywhere.
Is it actually safe to use DocZap for sensitive documents?+
Yes. Every tool processes your file locally using JavaScript and WebAssembly, so your document is never uploaded, never logged, and never visible to us. You can even disconnect from the internet after the page loads and those tools still work.
What PDF tools does DocZap offer?+
Merge, split, extract, and organize pages; compress, resize, crop, and rotate; convert between PDF, JPG, and PNG; sign, fill forms, watermark, redact, and password-protect — 31 tools in total, with more added regularly.
Which browsers does DocZap work in?+
Any modern browser — Chrome, Firefox, Safari, or Edge, on desktop or mobile. Every tool is built with standard web technology, so there's nothing to install.
