Perfect for Discord's 10MB free limit and email's 25MB. Drop a video, pick a size, get a clean MP4. No sign-up. No watermark.
Your export is often larger than chat/email limits. FitToMB makes it simple: drop a file, choose 10MB (Discord free tier) or 25MB (email), and we deliver a clean MP4 that just works.
Need to keep every detail while shrinking the file? Follow our compress video without losing quality guide for capture and export settings that stay sharp.
File size depends on duration and bitrate. We calculate a safe bitrate for your target and run a two-pass encode so the bits go where they matter most. If your clip is too long, we'll downscale (e.g., 720p → 480p) and gently cap the frame rate. Audio defaults to AAC 96 kbps to save room for picture.
Enter duration and target size to see the recommended video bitrate (we subtract audio automatically).
Need answers for a specific inbox? These guides keep videos under the cap and link directly into the right presets.
Some-shrinking a file always trades quality for size-but two-pass encoding and smart downscaling keep it watchable in chat windows.
MP4, MOV, MKV, and WEBM are supported. We output MP4 (H.264 + AAC) for maximum compatibility.
Cap resolution to 480p or lower the frame rate (30 → 24). Very long clips may require both.
