So we built the PDF toolkit we wished existed — fast, free, and private by design. This is why Plume works the way it does.
In 2024, one of us needed to merge a signed contract with an addendum. The first result online wanted an email address, then an account, then a subscription — all to combine two files. Worse: those files, full of personal details, were being uploaded to a server somewhere just to be stapled together.
That felt backwards. Modern browsers are powerful enough to do this work right on your device. There was no technical reason to send anyone's documents anywhere. The only reasons were business ones — funnels, upsells, and data.
So we made a different bet: build the tools to run entirely in the browser, keep the everyday ones free forever, and never see a single file. If we couldn't access your documents even if we wanted to, privacy stops being a promise and becomes a fact.
Three principles that decide every feature we build — and every one we don't.
Not a policy you have to trust — a design where your files physically never leave your device.
No watermarks, no daily caps, no sign-up wall. The everyday tools stay free because they cost us almost nothing to run.
One clear job per tool, done in a click. We'd rather do a few things beautifully than bury you in options.
Independent and small — with strong opinions about your privacy.
