FitToMB

FitToMB is a free, privacy-friendly web app that compresses videos to a precise target size. It’s perfect for hitting Discord’s 10MB free limit or email attachment limits like 25MB. Just drag and drop a video, choose 8/10/25MB or any custom size, and get a clean MP4 or AV1 with no watermark and no sign-up.

Under the hood, FitToMB calculates a safe bitrate for your target size, subtracting audio automatically, and runs a two-pass H.264 encode so bits go where they matter most. If the clip is too long for the size you picked, it can downscale (e.g., 720p ? 480p) and gently cap frame rate to preserve quality.

A built-in bitrate calculator shows the recommended video bitrate for your duration and target size. Files are transferred securely and auto-deleted after 1 hour.
