Descript's free MP4 compressor optimizes your videos to take up less space without sacrificing quality. Compress MP4s for faster downloading, share a link to watch them in Descript's web player, or convert M4V, MPEG, MOV, and other video file types into a compressed MP4 format. Descript is a video size reducer that’s not a video quality reducer.
Get started ->
To reduce MP4 size, first you need MP4s to compress. Upload those video files to Descript’s workstation. If you have other file formats, like MPEG or MOV, go ahead and upload them since Descript works as a video converter too.
Before running your video through the file compressor, you can easily trim it using the transcript editor—it's just one more way you can reduce the file size without affecting quality. After all, a shorter video requires less encoding, and Descript’s automatic transcription makes editing as easy as editing a doc.
Finally, to compress your video for social media, your website, or cloud storage, click Publish > Export. You’ll have the option to set the video’s resolution and dimensions of your exported video, or publish it directly to YouTube. You can also share it as a web link, which lets anyone view your MP4 online or download it.
Multiple ways to reduce the file size of MP4s
Cut your MP4s down to size to save valuable storage space on cloud drives like Google Drive and Dropbox. Host and share your MP4s online with Descript's built-in storage and web player. Adjust the quality, frame rate, or resolution to reduce file size. There's more than one way to ensure your MP4s take up less space with Descript.
