Free PDF tools that never upload your files

PDF Toolbox is a collection of 108 free tools for working with PDF files — merging, splitting, compressing, converting, signing, editing and more. Unlike typical online converters, the working tools here process your documents locally in your browser, so your files never leave your device. No account, no installation, and no upload limits, because there are no uploads.

What “runs locally” means here

Tools marked in-browser do all their work with JavaScript on your own computer or phone: the file you pick is read into your browser's memory, transformed there, and handed back to you as a download. Nothing is transmitted. Tools marked guide cover conversions that genuinely require a full office suite or specialist software (like Word or EPUB rendering engines) — instead of pretending, those pages explain the reliable ways to do the job and exactly what to watch out for.
