Drop files here or click to browse
Most "free online" converters upload your files to a server you can't see. Squishly doesn't. Every tool here runs entirely inside your browser using your own computer's power, so your documents, photos and personal files stay yours.
Your files are never sent to a server. Turn off your wifi after loading the page and every tool still works.
Files live in memory only and are gone the moment you close the tab. There are no accounts and no file logs. Any cookies are limited to your choices and, where enabled, ads (see our Privacy Policy).
Open-standard formats out. No watermarks, no "premium to remove limits", no catch.
Video, audio and Office files now work fully on-device too. They're genuinely harder than the rest, so here's exactly what to expect, with no surprises.
Powered by a real FFmpeg engine running in your browser. The first video job downloads the engine (~32 MB, once) and encoding is slower than a native app. Your video never leaves your device.
Open tool →Convert between MP3, M4A, WAV and OGG on-device via the same FFmpeg engine. Same one-time download, same total privacy.
Open tool →Turns Word documents into PDFs right here, including text, headings and lists. It's basic formatting, so exotic fonts, complex tables and embedded images may shift, since true fidelity needs a server we deliberately don't run.
Open tool →Jump straight to any tool or conversion. Each opens on its own page, ready to use.
