PDF Toolbox

Merge, split, compress, convert, sign and edit PDF files — entirely on your own machine.

PDF Toolbox opens a complete PDF workspace in a new tab. Every tool works on the same document in the same window — no jumping between pages, no re-uploading a file for each step. Everything runs on your own machine. No file is ever uploaded, there is no account, and there is no analytics or telemetry of any kind. ORGANISE • Merge — combine PDFs and images, reorder by dragging, or type an exact page number • Split — set as many cut points as you like and get one file per part • Remove — take pages out, and put them back from a recoverable list • Rotate — quarter turns or any angle, on any range of pages • Crop — drag a frame and apply it to one page, a range, or all of them OPTIMISE • Compress — four levels, each showing the size you would actually get • Upscale — redraw pages at higher resolution, or run an ESRGAN model over scans EDIT • Write — text boxes with font, size, colour, fill, border and rotation • Highlight — mark the words you select, the way a word processor does • Stamps — save a styled text block and reuse it anywhere • Watermark — across the middle, tiled or in the footer, at any angle • Background — replace or clear the page background CONVERT • PNG, JPG or CSV • Copy text — select text straight off the pages, or copy whole pages at once SECURITY • Add a password and set permissions, or save an unprotected copy Open source under the MIT licence.
