Compress video to 8MB
8MB is a tight target, common on early Discord, some forums and forms with attachment caps. Whether a video fits 8MB depends almost entirely on its length: shorter fits easily and stays sharp; over a minute or two it gets noticeably soft. The tool above is preset to 8MB — just drop a file in; trim long videos first.
Quick answer
To hit 8MB, the trick is deriving a bitrate from target size ÷ duration, then re-encoding. 8MB is the classic cap on older platforms (early Discord, some forums and upload forms). ConvertMeow re-encodes to an 8MB target locally in your browser — never uploaded, no watermark — and short clips usually land comfortably under it.

Target size
Derives a bitrate from target size ÷ duration and re-encodes; best for short clips.
How long a video fits in 8MB?
At a fixed size, quality is set by the bitrate that size ÷ duration allows. 8MB is small: a 15-second clip can look quite sharp; around a minute it softens; a multi-minute video at 8MB looks clearly blurry.
The most effective way to keep 8MB sharp is to shorten the clip — trim to the few seconds that matter first, then compress.
- ≤15 seconds: usually sharp at 8MB.
- ~1 minute: soft but watchable at 8MB.
- Several minutes: clearly blurry at 8MB — trim first.
Why 8MB instead of 10MB?
8MB (more precisely 8 MiB ≈ 8.39MB) is a hard cap on many older systems — early Discord, some forum attachments and upload forms all stop there. Staying under 8MB is the safe bet that satisfies these stricter cases.
Frequently asked questions
It gets close. ConvertMeow derives a bitrate from target size ÷ duration and re-encodes — short clips usually land comfortably under 8MB. Long videos may come out slightly over or under; it shows the real output size so you can tell.
It depends on length. A 15-second clip at 8MB looks quite sharp; over a minute or two it noticeably softens. For 8MB and sharp, trim the video shorter first.
No. Compression runs entirely locally in your browser with ffmpeg — never uploaded, no watermark, no cap.
