MOV
Video and audio are converted entirely in your browser — longer or larger files take more time.
Quality
Why convert MOV to WebM?
MOV files from an iPhone are large and not ideal for websites. WebM is an open web format that plays in modern browsers without plugins.
Is it safe?
Yes. This conversion runs entirely inside your browser, and your MOV file is never sent to a server. Metadata such as location is also removed automatically.

- 4Download each WebM file individually, or grab everything at once as a single ZIP.
Frequently asked questions
Is it really free?
Yes. Converting MOV to WebM is free with no sign-up and no watermark. The free plan handles several files per batch; an optional premium licence removes ads and raises the limits.
Are my files uploaded anywhere?
No. Your MOV files are read and converted by your browser on your own device. You can confirm it by opening your browser's developer tools and watching the Network tab while you convert: no file upload ever appears.
Will I lose quality?
That depends on the target. Lossless targets such as PNG keep every pixel. Lossy targets such as JPG and WebP let you choose the trade-off between file size and quality with the presets or the fine-tune slider.
Does it work on my phone?
Yes. It runs in any modern browser on iPhone, Android, Windows, macOS and Linux. Very large files may be slower on older phones because the work happens on the device itself.
What happens to photo metadata?
When an image is re-encoded, metadata such as GPS location and camera details is not carried over, so the WebM file you download does not reveal where the photo was taken.
