One app instead of ten browser tabs
The jobs you actually do with PDFs, done properly — with undo, redo and a version history behind every one of them.
Open, edit, save. That is the whole loop.
Open or drop a PDF
Drag a file onto the window, or drop several at once to merge them. Your document opens instantly — nothing leaves your machine.
Work on it
Reorder pages by dragging thumbnails, rotate, sign, stamp, highlight, fill forms. Every action is undoable and every version is kept.
Save it
Save over the original or export a copy, protected with AES-256 and the print and copy permissions you choose.
Your documents never leave your computer
Most "free PDF tools" upload your contract to a server you have never heard of. 1TruePDF does all of its work locally, which is why it also works on a plane.
- No uploads. Every operation runs on your own CPU.
- No account. Install it and open a file. That is the onboarding.
- No watermarks. The file you save is the file you made.
- Signed and notarised. macOS builds pass Gatekeeper without warnings.
