Compress Video to 50 MB
The target is set to 50 MB when the page opens. Nothing is uploaded.
The compressor opens with the After size set to 50 MB. Load a video and the estimate row shows the expected result next to the original size. If the clip is too long for its current resolution at 50 MB, the panel picks a lower one before you press Compress video.

Who asks for 50 MB
Discord allows 50 MB uploads with Nitro Basic and for all members of a server at boost level 2 (checked September 2026, Discord File Attachments FAQ, Server Boosting FAQ). The free limit is 20 MB; for that, use compress a video for Discord. GitHub warns about files larger than 50 MiB when you push them (checked September 2026, GitHub Docs).
This page counts 1 MB as 1,048,576 bytes. A service that counts 50 MB as 50,000,000 bytes may refuse a file this page shows as 49 MB; type 47 for those.
What fits in 50 MB
The panel keeps the resolution you chose under Screen size while the video bitrate stays above a minimum for that resolution. For a 30 fps clip with 128 kbps audio saved as MP4, 50 MB keeps 1080p up to about 4 minutes, 720p up to about 8 minutes and 480p up to about 16 minutes. Past those lengths the panel steps down, marks the row it chose with a dashed amber frame and shows "Resolution set to W × H to reach this size."
A 60 fps source keeps 1080p for about 2 minutes 50 seconds. Frame rate under Advanced has Original, 60 fps and 30 fps; at 30 fps the 4-minute figure applies again. Format changes the numbers too: with MP4 · HEVC, 1080p lasts about 6 minutes. A 4K source keeps 2160p only for about a minute; the 4K page covers that case.
Audio, small files and large ones
Audio stays as it is by default. The panel lowers it to 64 kbps only when even 240p cannot reach the target, which at 50 MB means a 30 fps video longer than about half an hour. If the source is already under 50 MB, the target starts at its own size and the panel shows "At this setting the file stays about the same size."
Multi-GB files work, because the result is written to disk while it is produced. Only the first audio track is kept, and audio with more than 2 channels is mixed down to stereo when it is re-encoded.
Frequently asked questions
How long can a video stay 1080p at 50 MB?
About 4 minutes at 30 fps in MP4 with 128 kbps audio. At 60 fps, a little under 3.
Why is the result slightly under 50 MB?
The bitrate is calculated for 98.5% of the target. The file is aimed about 1.5% under the number you set so it does not go over.
Will the sound get worse?
Not unless the clip is very long. Audio is kept as is until even 240p cannot fit the target; then the panel sets it to 64 kbps and shows "Audio set to 64 kbps to reach this size." You can also pick 128 kbps, 64 kbps or Remove audio yourself under Advanced.
Does it need an internet connection?
Only to load the page. The compression itself runs on your device.
