Compress video to 100MB
100MB is a quality-preserving target: the size is well down so uploads are faster and more reliable, but quality loss is minimal. It suits cases where the platform limit is already high (Reddit ~1GB, Telegram 2GB, Slack 1GB) and you just want a big file to upload reliably and cost the recipient less data. A roughly ten-minute video at 100MB usually stays quite sharp. The tool above defaults to 100MB.
Quick answer
To compress to 100MB, ConvertMeow derives a bitrate from target size ÷ duration, then re-encodes. 100MB is a high-quality target, great for reliably uploading to high-limit platforms like Reddit, Telegram and Slack — much smaller than the original with barely visible quality loss. It all runs locally in your browser — no upload, no watermark.

Target size
Derives a bitrate from target size ÷ duration and re-encodes; best for short clips.
How long and sharp can 100MB be?
100MB is quite roomy: a video under ten minutes at 100MB is usually very sharp; fifteen to twenty minutes is watchable; only past half an hour does it start to soften.
For nearly all phone/laptop viewing, 100MB is hard to tell from the original, while cutting the upload and download burden dramatically — a great target for reliably sending big files.
- ≤10 minutes: very sharp at 100MB.
- ~15–20 minutes: acceptable at 100MB.
- Half an hour-plus: starts to soften — use a higher target or trim.
Where is 100MB mostly used?
100MB is rarely a hard cap — it's a reliable-upload target: platforms like Reddit (~1GB), Telegram (2GB) and Slack (1GB) cap far higher, so compressing an original to 100MB is about smooth uploads and lower data use for the recipient, with almost no quality cost.
Frequently asked questions
It gets close. ConvertMeow derives a bitrate from target size ÷ duration and re-encodes — videos under ten minutes usually land comfortably under 100MB; longer ones may come out slightly over or under, and it shows the real output size.
Barely. 100MB is a high-quality target — a sub-ten-minute video at this size is hard to tell from the original on a phone or laptop. It's about making big files upload reliably and save data, not about sacrificing quality.
No. Compression runs entirely locally in your browser with ffmpeg — never uploaded, no watermark, no cap. Note: keep single files under roughly 500MB–1GB, as very large files strain the browser.
