Why people switch to SnapConvert
- Private by design. Typical online converters upload your file to their servers and keep it for hours. Here the conversion happens on your device using ffmpeg compiled to WebAssembly. A screen recording of your bank account or a voice memo from your doctor never leaves your computer.
- No queue, no limits. Because there is no server, there is no free-tier queue, no 100 MB cap and no "upgrade to convert faster" prompt.
- Works offline. After the page loads once, you can convert with the internet switched off.

Frequently asked questions
Is this converter really free?
Yes. There is no premium tier, no watermark and no daily limit. The site is supported by ads.
Where are my files processed?
On your own device. The page downloads a WebAssembly build of ffmpeg once and then converts locally. Nothing is uploaded, which is also why there is no size limit and no waiting queue.
Which browsers work?
Any recent Chrome, Edge, Firefox or Safari on desktop or mobile. Video conversion is much faster on a desktop computer.
Why does the first video conversion take a moment to start?
The 32 MB conversion engine has to download once. It is cached afterwards, so later conversions start immediately.
