Compress a Video to 50MB
Room for real quality — hit a 50MB cap exactly, without uploading anything.
Runs entirely in your browser. Your videos never leave this device.
50MB is the per-file cap on Zendesk ticket and messaging attachments, the upload limit for Discord Nitro Basic, and a common ceiling on job portals and internal document systems. At this size there's real room to work with — five minutes of video still gets over 1 Mbps. Pick the 50MB target and the encoder calculates the exact bitrate from your video's length, entirely in your browser.
How do I compress a video to under 50MB?
Drop the video into the compressor, pick the 50MB target, and download the MP4 — the whole job runs locally in your browser, with no upload step at all. The encoder divides 50MB by your video's duration to set the exact bitrate, and if the finished file lands over the target it automatically re-encodes at a lower rate.
The facts that matter
| Who caps at 50MB today | Zendesk attachments (50MB per file), Discord Nitro Basic, assorted job and government portals |
|---|---|
| 1–2 minutes at 50MB | ≈3.3–6.7 Mbps — good 1080p |
| 5 minutes at 50MB | ≈1.3 Mbps — clean 480p, decent 720p |
| 10 minutes at 50MB | ≈670 kbps — acceptable 480p |
| 20+ minutes at 50MB | ≈330 kbps or less — soft to rough; trim if you can |
| Output | MP4 (H.264 + AAC), aspect ratio and frame rate preserved |
Get a better result
- Trim dead air off the start and end — at a fixed size, every trimmed second raises the bitrate of the rest.
- Screen recordings and slide decks compress well; shaky handheld footage needs more bitrate to look right.
- Compressing a big source file? Close other heavy tabs first — the work happens in your browser's memory.
- Queue multiple files at once; they'll process one at a time while you do something else.
Frequently asked questions
What quality can I expect at 50MB?
Quite good for anything short. Under two minutes gets 3 Mbps or more — solid 1080p. Five minutes lands around 1.3 Mbps, which is clean at 480p and respectable at 720p. Ten minutes is about 670 kbps — watchable 480p — and beyond twenty minutes the picture goes soft.
Does it work for long videos like recorded meetings?
Yes, and screen recordings actually fare better than camera footage — mostly-static screens compress efficiently in H.264, so a talking-head-plus-slides recording at 670 kbps looks better than a handheld video at the same rate. Just expect the encode to take a while: it runs at browser speed, which is slower than a desktop app on long videos.
What if the result overshoots 50MB?
The tool checks the finished file's size against the target and automatically retries at a lower bitrate if the first pass came out over. You always end up with a file that's actually under the limit.
My source file is several gigabytes — will that work?
Usually, but very large inputs (over about 1GB) can strain browser memory, since everything happens on your device. If the tab struggles, close other tabs first, or trim the video into parts and compress them separately — the batch queue will take them one at a time.
Is anything uploaded while compressing?
No — the compressor is FFmpeg running as WebAssembly inside your browser, so the video never leaves your device. The only network activity is a one-time ~32 MB download of the engine itself, which is cached for future visits.
Are there file size or usage limits?
No daily limits, no signup, no watermark, and no artificial cap on input size. The practical constraints are your machine's memory on very large files and encoding time on very long ones.
