TikTok has become the go‑to platform for short‑form video, but its strict dimensions and format requirements can be a hurdle. This guide explains how to resize and edit your clips so they look flawless on the app, whether you’re on Windows, macOS, the web, or a mobile device.
Why Accurate Resizing Matters
Keeping your footage at the correct aspect ratio (9:16), resolution (1080 × 1920 px), and file type (MP4 or MOV) ensures your content appears crisp and uninterrupted on TikTok. TikTok now allows up to 10‑minute uploads, yet most successful videos stay between 13–24 seconds, and generally under three minutes.
