PDF tools that never upload your files
Merge, split, rotate and rearrange PDFs without sending them anywhere. The work happens inside your browser, on your own machine, which is why there is no signup and no daily limit.

Why your files never leave your device
Most PDF sites work the same way. You pick a file, the browser sends it to a server, a program there does the work, and you download the result. Your document sits on somebody else's computer for the length of that round trip, and often for an hour or two afterwards while the download link stays valid.
This site works differently for 6 of its 6 tools. The PDF library that does the merging and splitting is written in JavaScript and WebAssembly, which means the browser can run it directly. When you drop a file on a tool page, the browser reads it from your disk into its own memory, the library rewrites it there, and the result is handed back to you as a download. At no point does the file travel over the network.
You can check this rather than take our word for it. Open your browser's developer tools, switch to the network tab, and use any tool on the site. You will see the page and its code load, and then nothing while the work happens. Or disconnect from the internet entirely once the page has loaded. The tools keep working, because there is nothing for them to reach out to.
The practical consequences are the ones people care about. There is no upload wait on a large file. There is no daily task limit, because no server resource is being consumed. There is no retention policy to read, because there is nothing to retain. And a confidential document stays confidential without you having to trust a privacy page.
Questions people ask
Are these PDF tools really free?
Yes. Every tool on this site 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 upload my files to a server?
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.
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 limit on file size?
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.
What happens to my file after I use a tool?
Nothing, because it never left your device. Close the tab and the copy the page was working with is gone. Your original file on disk is never modified.
