Compress your MP4 by selecting the compression level that best fits your needs. Adjust the CRF (Constant Rate Factor) between 0 and 51 to balance video quality and file size. Lower values retain more detail, while higher values create smaller files with stronger compression. This gives you complete control over the final output instead of relying on fixed presets.
Know what to expect before exporting your compressed video. As you change the compression settings, the tool displays both the original file size and the estimated output size in real time. This helps you decide whether to prioritize quality, storage space, or faster file sharing. Seeing the expected result before saving makes compression more predictable.
Reduce file size even further by selecting the most appropriate resolution. Keep the original resolution or choose 1080p, 720p, 480p, 360p, or 240p depending on where the MP4 video will be used. Lower resolutions help create smaller files for email, messaging apps, or web uploads, while higher resolutions preserve more visual detail.
Before saving your video, you can also trim unwanted sections, crop the frame, rotate the video, flip it horizontally or vertically, and adjust playback speed. Completing multiple edits in one session eliminates the need to switch between different tools. This saves time while simplifying your workflow.
Compress MP4 videos directly from your browser without installing software or creating an account. Upload files from your computer, drag and drop them into the workspace, or import them from Google Drive or Dropbox. The tool works across any device, making it easy to compress videos wherever you are. Your video is processed securely throughout the editing process.
Start compressing MP4 videos immediately without creating an account or installing software. Upload your MP4, choose the compression settings, preview the estimated file size, and download the optimized video. The entire process is free to use, with no registration, subscriptions, or hidden charges.
