About pdflu

pdflu is a free suite of online PDF tools designed around one simple principle: your files should stay yours.

What pdflu is

pdflu offers a growing collection of tools for working with PDF files — merging, splitting, rotating, compressing, adding page numbers and watermarks, organizing pages, signing, converting images to PDF, and more. Everything you need to handle everyday PDF tasks, all in one place, completely free.

What makes us different

Most online PDF tools upload your files to their servers to process them. That means your documents — which may contain personal, financial, or confidential information — leave your device and sit on someone else's computer.

pdflu is built differently. The majority of our tools run entirely in your browser. Your files are processed on your own device and never uploaded anywhere. Nothing is stored, nothing is transmitted, and nothing is seen by us or anyone else. When you close the tab, everything is gone.

Our principles

• Privacy first. Your files stay on your device. We can't see them, and we don't want to.
• Free to use. No sign-up, no account, no watermarks on your output.
• Simple and fast. Clean tools that do one job well, without clutter or confusing steps.
• Accessible anywhere. Works on any modern browser — desktop, tablet, or phone — with nothing to install.

Who we are

pdflu is an independent project built and maintained by a small team passionate about privacy-respecting software. We believe useful tools don't have to come at the cost of your privacy, and we're committed to keeping pdflu free, private, and continuously improving.
