Compress MP4 Online Free
How to finish the file
- 01
Open FastEdit
Go to app.fastedit.net. The video editor runs in your browser using WebAssembly, no installation or account required.
- 02
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.
- 03
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.
- 04
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.
- 05
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 server-side cap, so you can compress 4K videos that cloud tools reject, subject to your device memory.
- 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.
Shrink the file, keep the quality in sight, and never hand over the original.
