Phone clips, screen recordings and exports often get too large to send or publish. Compress MP4, MOV, WebM, MKV and AVI to a practical size—no account required, no watermark on download.
The Balanced preset usually cuts size while keeping a clear look. Choose Smaller size when messaging apps reject the file. You can also convert the format or extract audio with our other video tools.
No install and no sign-up. Download the result as soon as compression finishes—nothing stamped on the picture.
Higher quality, Balanced and Smaller size cover everyday sharing versus strict size limits. Start with Balanced for most clips.
Import common MP4, MOV, WebM, MKV and AVI files and export a widely compatible MP4 for sending, publishing and backup.
Video compression reduces file size while trying to keep the picture looking good. Use it before messaging, homework uploads, cloud storage or web posts when an MP4 or MOV is too large.
No watermark and no required payment or account. Many free tools add a logo or daily caps; here you download a clean file when compression finishes.
No install needed. Pick a file and a preset, then start compression and download the result. For very large or long clips, trim or lower resolution first.
Common MP4, MOV, WebM, MKV and AVI inputs work; output is MP4. Aim for under 500MB per file. Very long 4K clips may hit device memory limits—trim first or use a computer.
Use Balanced for everyday sends. Higher quality keeps more detail; Smaller size lowers bitrate and caps very high resolutions for chat apps. Preview before you download.
