Processed on your device - nothing is uploaded.
HOW IT WORKS
1
Drop the mov file
Add your MOV video by dragging it in or browsing. It stays on this device.
2
Confirm WEBM
The video is re-encoded as WEBM using an encoder running in this tab.
3
Download
The WEBM file saves straight back - no upload, no queue, no copy kept.
Why convert here, not there
No upload, ever
Cloud video tools take your mov onto their disks. This one keeps it in your tab.
Local conversion
There is no file-upload step. Click Convert to start; the engine may need to load before conversion begins.
No account, no daily cap
No queue position, no throttling, no watermark burned into the webm.
The two formats, briefly
| MOV | MOV is a container used by cameras and editing software. The codecs inside it determine how it can be decoded and played. | |
|---|---|---|
| WEBM | WebM is a media container. This converter writes VP8 video at a fixed 1 Mbps with Vorbis audio when present. | |
When you need this
- Convert MOV when your target app asks for WEBM or does not decode the codecs in the source. This tool re-encodes rather than simply renaming the file; test playback before discarding the original.
MOV vs WEBM: what changes
| MOV | WEBM | |
|---|---|---|
| Kind | Video | Video |
| Compression | Depends on source encoding | Depends on output encoding |
| Typical size | Depends on the file and encoding settings. | Measure the exported file; it may be larger. |
| Opens on | Check the source in your app and browser. | Check the downloaded file in the receiving app. |
| Best for | Keep the original as your source. | WEBM workflows, subject to the limits below. |
Keep the original. Compare the exported file before sharing or replacing it.
Good to know
- This path writes VP8 video at a fixed 1 Mbps with Vorbis audio when present. The quality menu does not alter that path; detailed video can lose visible detail.
- First use downloads the audio/video engine (about 30 MB). The input cap is 2 GB, but available browser memory can run out below that.
MOV to WEBM, answered
Why convert MOV to WEBM?+
Convert MOV when your target app asks for WEBM or does not decode the codecs in the source. This tool re-encodes rather than simply renaming the file; test playback before discarding the original.
Which quality should I pick?+
This path writes VP8 video at a fixed 1 Mbps with Vorbis audio when present. The quality menu does not alter that path; detailed video can lose visible detail.
Does converting MOV to WEBM lose quality?+
Video is re-encoded with lossy compression. Detail can change, and tracks, subtitles or metadata may not survive. Keep the original and inspect picture, sound and sync.
Is there a file size limit?+
The hard cap is 2 GB per file. The practical limit is your device: conversion runs in its memory, so very large files can fail on phones with little free RAM. There is no server-side cap because nothing is uploaded.
Does my file get uploaded anywhere?+
Never. Your mov file stays inside this tab; the webm is produced by code on your device. Its contents never leave your device.
