Compress WebM for Discord
Compressing WebM for Discord comes down to three constraints: Discord's 10 MB cap, its 1280:720 resolution ceiling, and the need to output MP4 H.264 for reliable inline playback. WebM source files are typically 1080p screen recording (Loom default) at around 30 MB per minute — 68% over Discord's 9.5 MB target. We calculate a per-clip bitrate budget from your duration, subtract 128 kbps for audio, and allocate the remainder to H.264 video at the highest quality that fits. WebM's VP8/VP9 video + Opus audio get transcoded to H.264 + AAC, since most platforms reject WebM. Discord does not play WebM inline, so this page does a format conversion (WebM → MP4 H.264) plus the size compression in a single pass.

How to compress WebM for Discord
- 1Drag your .webm file onto the upload zone above (or browse to it).
- 2Discord is already selected — we'll target 9.5 MB to stay safely under the 10 MB cap.
- 3Optionally trim to a highlight clip or switch to H.265 for 30-50% smaller files at the same quality.
- 4Download the compressed MP4 and share it on Discord. Source file auto-deletes from our servers after 1 hour.
What to know about WebM → Discord
- WebM's VP8/VP9 video + Opus audio get transcoded to H.264 + AAC, since most platforms reject WebM.
- Resolution is downscaled to fit 1280p for clean output at the required bitrate.
- Trim to the highlight before you compress — every 10 seconds you cut gives remaining frames more bitrate to work with.
- Discord's 9.5 MB target leaves a 5% safety margin below its 10 MB hard cap, so platform-side rejection is never an issue.
The compression math
A 1-minute WebM at 1080p screen recording (Loom default) = ~30 MB. Discord's 9.5 MB target minus 128 kbps audio = ~1200 kbps video budget. H.264 at that budget downscaled to fit 1280p for clean output at the required bitrate produces a file at the target size that plays inline on Discord.
About WebM files
WebM is Google's open, royalty-free video format that uses VP8 or VP9 video codecs. It's widely used by browser-based screen recorders (like Loom exports), Chrome extensions, and web applications. While WebM plays natively in Chrome and Firefox, it has poor support on iOS devices and is rejected by most social media platforms. CompressYourVideo.com converts WebM to compressed MP4 (H.264), making it compatible with every device and platform. This is especially common for screen recordings from browser tools, which default to WebM output. The conversion preserves video quality while often reducing file size, since H.264 is more efficient than VP8 at equivalent quality levels.
