TikTok Video Resizer – Perfect 9:16 Vertical Dimensions

TikTok videos should be 1080×1920 pixels at a 9:16 aspect ratio. This is the standard vertical format that fills the entire screen without letterboxing. Videos at other ratios will display with black bars or be cropped by TikTok's player.

Yes, but landscape videos display with large black bars above and below (letterboxing). They also take up less screen real estate, which typically reduces engagement. For best results, shoot and export in 9:16 vertical format, or use a vertical crop of your landscape content.

TikTok recommends a minimum resolution of 720p (720×1280) for video uploads. While the platform will accept lower resolutions, 1080×1920 is the target for optimal quality. TikTok compresses all uploads, so starting with higher resolution helps maintain quality after compression.

TikTok supports MP4 and MOV file formats for video uploads. For profile photos and video thumbnails, JPG and PNG are supported. WebP is not currently supported for uploads, but TikTok may convert your content to WebP for delivery.

As of 2025, TikTok allows videos up to 10 minutes in length (60 minutes for some accounts). However, the sweet spot for engagement is 21-34 seconds. Videos under 60 seconds tend to have the highest completion rates.

Yes, TikTok applies significant compression to all uploads. To get the best quality after compression, upload the highest resolution your camera produces (within reason), use a high bitrate, and avoid uploading already-compressed files. A 1080×1920 video at 30fps with a high bitrate will look better after TikTok's compression than a low-bitrate source.

TikTok profile pictures display at 200×200 pixels and should be uploaded as a square image. Like other platforms, TikTok crops profile photos into a circle, so center your subject and leave padding around the edges. Upload at least 400×400 pixels for sharp results.
