These companies use Descript. Not bad!
01
To reduce MP4 size, start by uploading your video files to Descript’s workstation. If you have other formats, like MPEG or MOV, upload them too, as Descript can serve as a video converter .
02
Before using the file compressor , trim your content in the transcript editor — another way to cut file size without losing detail. Shorter videos generally require less encoding, and Descript’s automatic transcription makes editing feel like working in a doc.
03
Export your smaller MP4 file and share it on Discord, TikTok, Instagram, or via email. Need a quick share link instead? Share it with Descript’s built-in web hosting , complete with an embedded player and a download button.
Cut MP4 files down to manage storage on services like Google Drive and Dropbox. Host and share your MP4s online with built-in storage and a web player from Descript.

Whether you’re uploading to TikTok, Instagram, YouTube, or Discord, Descript’s MP4 compressor lets you instantly resize and optimize your video for each platform’s requirements.

Perfect for when different platforms or clients require specific file types. You can even downscale HD MP4s to lighter, faster-loading formats while keeping playback smooth.
