Convertio Alternative
Convertio uploads your files and limits free use by size and daily count (around 100 MB on the free tier). File Transmute keeps files on your device — no upload, no size-based paywall for in-browser tools, and it works offline.

Frequently asked questions
Yes — especially if privacy or speed matter. File Transmute converts files directly in your browser, so they're never uploaded, there's no upload wait, and the in-browser tools are free and unlimited. Convertio processes files on its servers, which is better suited to very large files or niche server-only formats.
In-browser conversions (most PDF, image, and document tools, plus OCR) are free and unlimited with no sign-up. A Pro plan adds large files, the API, and server-powered conversions.
Not for in-browser conversions — they run on your device and a live panel shows 0 bytes uploaded. A few advanced conversions (e.g. PDF → Excel) run on the server and are clearly labeled.
No. The in-browser tools work immediately with no sign-up and no email — unlike most cloud converters, which gate the free tier behind an account.
No daily limit on the in-browser tools. Because the conversion runs on your own device rather than on our servers, there's no per-user cost to meter — which is exactly why Convertio and similar services have to cap their free tier.
Yes. Once the page has loaded, in-browser conversions keep working with no connection — you can turn off your Wi-Fi and convert. A server-based converter like Convertio cannot do this by design.
Being honest: if you need very large files processed, a long tail of niche or exotic formats, or heavy batch automation on their infrastructure, a server-side service like Convertio is the right tool. File Transmute is built for the everyday PDF, image, document, audio and video jobs — done privately and instantly.
