About PDFtone
PDFtone started from a simple annoyance: every "free" online PDF tool wants to upload your file to a stranger's server first. We built the workspace we wanted — one that does the work on your own device.
Most online PDF editors are built around an upload-process-download loop. That means your contract, your ID scan, or your tax return takes a round trip through someone else's infrastructure before you ever see the result.
Modern browsers are powerful enough to do real document work — rendering pages, editing them, exporting to other formats — without any of that. PDFtone is built entirely on open-source libraries that run client-side: pdf.js for rendering, pdf-lib for editing and export, mammoth.js and SheetJS for Word and Excel conversion.
That's the whole premise. Everything you see in the workspace — merging, signing, converting, compressing — happens in memory, in your browser tab, and disappears when you close it (unless you choose to save your work to an account).
There's no toggle for "don't upload my file" because nothing is ever uploaded in the first place.
The core toolkit is free and usable without signing up. Accounts exist for people who want saved projects and sync — not as a gate.
PDFtone leans on well-established open-source libraries rather than reinventing PDF parsing from scratch, so the tools are reliable and battle-tested.
Paid plans raise page limits and add account features — they don't unlock tools that were artificially withheld on the free tier.
