— Your files stay put

Every tool runs on your device. Contracts, statements, IDs — none of it is uploaded to a server.

— No account, ever

Open a tool and use it. No sign-up wall, no email, no "verify to download".

— No limits, no watermark

Process as many PDFs as your device can handle. The output is clean and entirely yours.

Private PDF tools that run entirely in your browser

Most "free PDF tools" work the same way: you upload your document to their servers, they process it, and they hand back a download. For a flyer, fine — but a signed contract, a bank statement, a medical form, or an ID scan is a different matter. Unfuss takes a different approach. Every tool here runs as JavaScript inside your browser tab, using engines like pdf-lib and pdf.js. Your file's bytes never leave your device.

That single design choice removes the usual downsides of online PDF tools — no upload wait, no privacy exposure, no daily cap, no watermark, and no account. Bookmark any tool and it even keeps working offline after the first load.

What you can do

Frequently asked

Are these PDF tools really free?

Yes. Every tool is free, with no account, no watermark, and no daily task limit.

Do my PDFs get uploaded to a server?

No. Every tool processes your file inside your own browser using JavaScript. The file never leaves your device, so it keeps working even with Wi-Fi off after the page loads.

Do I need to install anything?

No. Everything runs on a web page in any modern browser — Windows, Mac, Linux, iPhone, and Android.

Is there a file size limit?

There's no artificial cap. The practical limit is your device's memory — most documents, including large scans, are no problem.
