Video Spec Checker

Will this video upload as a Short? Will it fill the phone screen? Drop it in to check length, shape, resolution and frame rate for each platform. The video is read by your browser and never uploaded.

The safe settings

For short-form video, 1080×1920 (9:16) at 30 frames per second in MP4 (H.264 video, AAC audio) works everywhere. For YouTube long-form, 1920×1080 (16:9).

Limits were checked in October 2026; platforms change them now and then. Next, make sure nothing important sits under the app's buttons, and check the sound level with the loudness checker.
