TikTok is vertical — crop to 9:16
TikTok is built for full-screen vertical video at 9:16 (1080×1920). Upload a landscape or square clip and TikTok either pillarboxes it or crops it for you. Crop to 9:16 yourself above so you decide what stays in frame — and your clip fills the whole screen.
The crop control center-crops your video to 9:16 on your device. Pair it with the quality preset to keep a sharp 1080p that still looks good after TikTok’s own compression.
Fit TikTok’s upload limit
TikTok’s in-app upload limit is around 287 MB on iPhone and 72 MB on Android, with larger files allowed from the website. A quick compress keeps you comfortably under the cap and uploads far faster on mobile data.
TikTok re-encodes every upload, so handing it an efficient H.264 MP4 — not a giant raw file — means a faster upload and fewer artifacts in the final video.
Frequently asked questions
What aspect ratio does TikTok use?
TikTok is vertical 9:16 (1080×1920). Crop your video to 9:16 above so it fills the screen instead of letting TikTok pillarbox or auto-crop it.
How do I crop a landscape video for TikTok?
Pick 9:16 in the crop control — the tool center-crops your landscape clip to vertical. Then compress and download, and upload the 9:16 MP4 to TikTok.
What’s TikTok’s file size limit?
About 287 MB from an iPhone and 72 MB from Android in-app; larger files are allowed from the TikTok website. Compressing keeps you under the limit and uploads faster.
Is my video uploaded to your servers?
No. Cropping and compression run entirely in your browser — nothing leaves your device. You upload the finished clip to TikTok yourself.
