About PDF Toolbox

PDF Toolbox is a free set of PDF tools built for one simple reason: most people who need to merge, split, compress or convert a PDF just want the task done, without creating an account, installing software, or trusting a stranger's server with a private document.

Wherever it's technically possible, every tool runs entirely inside your browser using modern web technology — your files are read, processed and turned into a result on your own device, never uploaded anywhere. That's not a marketing claim; it's how the tools are built.

What we offer

Merging, splitting, compressing, converting between PDF and image formats, rotating and reorganizing pages, adding watermarks, text and signatures, and protecting or unlocking PDFs with a password — all in one place, all free.

How it's funded

PDF Toolbox is supported by advertising rather than subscriptions or paywalls, so every tool stays free and open to use without limits.
