Under the limit.
Still looks good.
Re-encode an MP4 or MOV to hit Discord, email, or half-size targets — using your device's own hardware encoder. No upload, no watermark, no 30 MB download.
How do I compress a video for Discord or email? Add the MP4, pick a target (10 MB for Discord, 25 MB for email, or half size) and a resolution — 720p is the sweet spot — then press Compress. The re-encode runs on your device; nothing is uploaded.
Video compressor
Re-encoding happens on your GPU/CPU — a 1-minute 1080p clip typically takes 10–40 seconds. Keep the original file; this tool writes a new MP4 and never touches your source.
How video compression works here
The tool demuxes the MP4, decodes each frame with the browser's media pipeline (WebCodecs), optionally scales it, and re-encodes with H.264 at a bitrate computed from your target. Audio is re-encoded to AAC 128 kbps. Everything runs on your device — the file never leaves the tab, which you can verify in the Network panel.
What actually makes a video small
- Bitrate — the master dial: 10 MB for a 1-minute video means ~1.3 Mbps of video. Fast motion needs more; talking heads need less
- Resolution — dropping 4K to 720p cuts pixels 9×; for chat and phone viewing it's usually invisible
- Duration — the only free win: trim it and everything else gets easier
The presets do the math: Discord's free tier caps at 10 MB, most email stops at 25 MB, and some portals ask for 2 MB. If the computed bitrate drops below ~300 kbps the tool warns you — at that point drop the resolution too, or accept visible softness.
Honest limits
Input is MP4/MOV/M4V with H.264 or HEVC video — that covers phones (iPhone records HEVC), cameras, and most downloads. WebM/MKV input isn't supported yet; if you recorded with our screen recorder (WebM), remux or record again as MP4 for now. Output is always MP4 with H.264 + AAC — the combination Discord, email clients, and government portals accept without complaint. And re-encoding always costs some quality: check the result before deleting the original.
After compression
Need the audio only? The video to MP3 tool extracts it. Compressing images instead of videos? The target-size image compressor works the same way — pick the number, hit the target.
How do I compress a video to under 10 MB?
Load the MP4, pick the Discord (10 MB) target and a resolution — 720p keeps most detail — then press Compress. The tool re-encodes the video locally using your device's hardware encoder; nothing is uploaded.
Will the quality drop?
Any size reduction re-encodes the picture. At 720p and a reasonable bitrate most viewers won't notice on a phone or laptop screen; heavy compression shows as softness in fast motion. The tool tells you the exact bitrate before you start.
Which formats are supported?
Input: MP4, MOV, and M4V (H.264/HEVC video with AAC audio). Output: always MP4 (H.264 + AAC) — the most compatible combination for Discord, email, and portals.
Why does it need Chrome or Safari 17+?
The re-encoding uses WebCodecs — the browser's built-in media pipeline. Chrome, Edge, and Safari 17+ have it; Firefox support is still rolling out. The tool checks and tells you if your browser can't do it.
