PDF tools that respect where your files live
PDFDig started from a simple frustration: doing something as ordinary as merging two PDFs usually means handing your documents to a stranger's server. We thought that was backwards.
The idea
Browsers have quietly become capable of serious document work. Parsing a PDF, rearranging its pages, rendering it to images, re-saving it — all of this can happen on your own machine, in a single tab, without a network request ever carrying your file.
PDFDig is built entirely around that capability. There is no upload step to remove because we never added one. Your documents stay on your device from the moment you open them to the moment you download the result.
What we don't do
We don't run AI features that send your text elsewhere, we don't store your files, and we don't require an account. The only things kept in your browser are small preferences and an optional, file-free history you control.
Privacy by architecture
Privacy isn't a setting you toggle — it's a consequence of where the work happens. Because files never leave your device, there's nothing for us to protect on a server, because there's nothing there.
Local by default
Every tool runs in your browser using open libraries. Your CPU does the work. The result is generated on your device and handed straight back to you.
Honest about limits
Some features can't be done well, or at all, purely in a browser. We label those clearly as experimental or unavailable rather than pretending otherwise.
Light and fast
No accounts, no dashboards you don't need, no upload-and-wait. Open a tool, do the thing, move on.
