Compress MP4 Online Free
Steps
Open FastEdit
Go to app.fastedit.net. The video editor runs in your browser using WebAssembly, no installation or account required.
Load your MP4 video
Drag and drop your MP4 file onto the editor. It is loaded locally, and your video is never uploaded to any server.
Choose your codec
Select H.264 for maximum compatibility (plays everywhere) or H.265 (HEVC) for 30-50% smaller files at the same quality. H.264 Baseline profile is safest for web and mobile playback.
Adjust bitrate and resolution
Lower the bitrate to reduce file size: 2-5 Mbps is sufficient for 1080p web video, 1-2 Mbps for 720p. Optionally reduce resolution if the original is larger than needed.
Export your compressed video
Preview the compressed video, then click Export. Use fit-to-size if you need the output to meet a specific file size limit.
Benefits
- A typical 200MB phone video compresses to 20-40MB at 1080p with no visible quality loss.
- H.264 output plays on virtually every device, browser, and platform without transcoding.
- Trim video before compressing to cut unnecessary footage and reduce file size further.
- No upload means no file size limits, so you can compress 4K videos that cloud tools reject.
- Batch process multiple videos with the same compression settings.
Compression Tips
- H.264 Baseline profile plays on virtually every device and browser. Use it when compatibility is the priority.
- H.265 (HEVC) delivers 30-50% smaller files than H.264 at the same quality, but compatibility is more limited, and not all browsers support it.
- For 1080p web video, 2-5 Mbps bitrate is usually sufficient. Higher bitrates produce marginal quality gains but significantly larger files.
- Reducing resolution from 4K to 1080p can cut file size by 60-75% with no visible difference on most screens.
- Two-pass encoding produces better quality at a given bitrate by analyzing the video first, then allocating bits optimally.
