Edit PDFs without uploading them
Uploading a sensitive document to an unknown server is a privacy risk you don’t have to take. PlinyPDF’s local tools process your PDF entirely in your browser — you can confirm nothing is uploaded in your browser’s DevTools Network tab.
Annotate, sign, watermark, organize, and protect PDFs without your file ever leaving your device.
Frequently asked questions
How do I know my file isn’t uploaded?
Local tools run via WebAssembly in your browser. Open DevTools → Network and you’ll see no file upload.
Which tools run locally?
Most of them — merge, split, rotate, annotate, sign, watermark, organize, protect, and more. Cloud-only tools (like PDF to Word) are clearly labelled.
Is it free?
Yes — local tools are unlimited and free, with no account and no watermark.
