How Client-Side PDF Processing Works

The same three steps every time, and the file never leaves your device.

Step one

You pick a file

The browser hands the tool a copy in memory. Nothing is written to a server.

Step two

The work runs here

Code loaded once with the page does the merging, splitting, converting or compressing on your machine.

Step three

You save the result

The new file is built in memory and saved straight to your downloads folder.

Frequently Asked Questions About Browser PDF Tools

Is my file really not uploaded?

Yes. Every tool runs in your browser. Open your browser's network panel, run a merge, and you will see no request carrying your file.

Does it work without an internet connection?

Once a tool page has loaded, it can keep working if you go offline, because the code is already on your device.

What about very large documents?

Size is limited by your device's memory, not by an upload cap.

Will everything stay in the browser?

Yes. All our tools run entirely in your browser, and your files never leave your device. If we add tools that need more processing power later, they will be clearly marked and optional.

What does it cost?

All our browser tools are free and stay free.
