Good to know
- WEBM uses different video and audio formats from MP4, so the file is always re-encoded, to H.264 and AAC. Flecto uses your graphics card when it can.
- A WEBM with a transparent background loses its transparency, because standard MP4 video cannot store it.
- A re-encoded MP4 keeps the first video track and the first audio track. Extra audio tracks and subtitles are not carried over.
- Audio and video conversions use FFmpeg. Flecto offers to download it once, and after that it works offline.
- The free plan includes 10 conversions every week. Failed or cancelled files do not count.
Where WEBM files come from
WEBM is the open video format of the web. Browser-based screen recorders, online meeting tools and many websites produce it because every modern browser can play it without licence fees.
Outside the browser it is less welcome: iPhones, many video editors, presentation software and messaging apps expect MP4. Converting gives you one file that works in all of them. The same dial also goes the other way, from MP4 to WEBM.
Questions
Can I convert MP4 to WEBM too?
Yes. Select the MP4, hold Shift, right-click, choose Video and pick WEBM.
Why does my screen recording save as WEBM?
Recorders that run in a browser use the browser’s built-in encoder, and that produces WEBM.
Is my file uploaded?
No. The conversion runs on your PC, and the file never leaves it.
Can I convert several files at once?
Yes. Select them together, then use the same Shift and right-click menu. The dial offers the formats they can all use.
