Resolution options include original size, or scaling to width 1280, height 720, or height 480 while keeping the aspect ratio
No uploads required, and you can see the before/after file size at a glance

Use cases

Compressing videos for upload, sharing over WeChat or email, freeing up storage space, and keeping file sizes in check before posting.
