Why your files stay on your device
Most PDF sites upload your file to a server, process it there, and delete it eventually. This site runs the same libraries directly in your browser, so merging, splitting and rearranging happen on your machine and nothing is transmitted or stored. Every one of the 20 tools here works that way today. If a tool is ever added that needs a heavier engine than a browser can run, it will carry a Processed on our server badge and say so before you choose a file.
How it works in detailFrequently asked
Are these PDF tools really free?
Yes. Every tool is free with no account, no daily task limit and no watermark added to your files. There is no paid tier holding features back.
Do you store my files?
Not for the tools marked as running in your browser. Those read your file with JavaScript on your own machine and write the result there too, so nothing is transmitted and there is nothing for us to keep.
How can a website edit a PDF without uploading it?
Modern browsers can run real programs, including PDF libraries compiled to JavaScript and WebAssembly. The library runs inside the page on your device, the same way a desktop application runs on your computer.
Is there a file size limit?
There is no limit we impose. The practical ceiling is your device's memory, because the document is held there while it is being rewritten. A laptop handles a few hundred megabytes comfortably.
Do I need to install anything?
No. The tools run in the browser you already have. There is nothing to download and no extension to add.
Can I use it without an internet connection?
Once a tool page has loaded, yes. The tools that run in your browser keep working with the network switched off, which is the simplest way to prove nothing is being uploaded.
