Drop the MP4 onto the compressor above. The 50 MB target is already set, so just click Compress and download the result. ### Will the file be exactly 50 MB? It aims to land at or just under 50 MB. 50 MB here means 50,000,000 bytes, so it also fits sites that count 1 MB as 1,048,576 bytes. ### How much quality will I lose at 50 MB? 50 MB fits several minutes of 720p or 1080p video, which covers most presentations and intros. For a 1-minute clip, 50 MB leaves about 6.7 Mbps for video and audio together (1080p, high quality); a 3-minute clip gets 2.2 Mbps (1080p or 720p). ### My MP4 is already smaller than 50 MB. What now? Then it already fits, and compressing it further would only cost quality. Upload it as it is, or pick a smaller target if you need it smaller still. ### What if my MP4 can't get down to 50 MB? If a video is too long for 50 MB, the quality would drop too far. Trim it to the part you need, or pick a larger size. ### What is 50 MB typically needed for? Common reasons: course and assignment submissions; job applications that accept a video introduction; ad and marketplace platforms with 50 MB limits. Limits vary by site, so check the exact number where you're uploading. ### Is my MP4 private? Yes. It's compressed inside your browser and never uploaded.
