Why your files never leave your device

Most sites in this category either upload everything and stay quiet about it, or claim nothing is ever uploaded while quietly making exceptions. Neither is much use when you are deciding whether to run a contract through a free web tool.

Here it is plainly: there is no server. This site is a set of static files. Your PDF is read straight off your disk by JavaScript, processed with WebAssembly, and handed back to you. No request carrying it is ever made — not because we promise not to, but because there is nowhere for it to go.

You do not have to take our word for it. Open your browser's developer tools, switch to the Network tab, and merge or compress a file. You will see the page's own scripts load and nothing else. We also run an automated test on every build that drives each tool through a real conversion and fails if any request crosses origins or carries a body, so this cannot quietly regress. More on how it works.

Frequently asked questions

Are my files uploaded to a server?

No — not by any tool, with no exceptions. Every tool runs entirely inside your browser tab using JavaScript and WebAssembly. There is no upload endpoint to send a file to, because the site is a set of static files with no backend at all. You can confirm it yourself: open your browser's developer tools, switch to the Network tab, and run any tool. Nothing is sent.

Is it really free, with no watermark?

Yes. Every tool is free with no usage limit, no watermark on the output and no account. There is no paid tier that removes a restriction, because there is no restriction to remove.

Do I need to sign up or install anything?

No. Everything runs in a normal web browser on Windows, macOS, Linux, Android and iOS. There is nothing to download and no account to create.

How can PDF editing work without a server?

Modern browsers can run compiled code through WebAssembly at close to native speed, and they already contain a full PDF rendering engine. That combination is enough to merge, split, compress, rotate and convert PDFs locally — work that genuinely needed a server ten years ago.

Does it work offline?

Yes. Once a page has loaded, its tool keeps working with the network switched off entirely, because there is no server to talk to. Try it — disconnect and merge a file.

Is there a file size limit?

There is no limit we impose, because there is no upload to meter. The practical ceiling is your device's available memory: large files are fine on a desktop and may struggle on an older phone.

Is this safe for confidential documents?

Yes. Because no file is ever transmitted, using any tool here carries the same disclosure risk as opening the document on your own computer — which is to say, none. That holds for contracts, medical records, bank statements and identity documents alike.
