What is Twitter/X's video size limit?

What video format does Twitter/X support?

Twitter supports MP4 (H.264 video, AAC audio) and MOV formats. MP4 is strongly recommended as it's the most compatible. Maximum resolution is 1920x1200 (or 1200x1920 for vertical). Minimum resolution is 32x32.

Why won't my video upload to Twitter/X?

Common issues include: file too large (over 512MB), wrong format (use MP4), video too long (over 2:20 for free users), or resolution too high. Use this tool to compress and convert your video to the right specifications.

What is the best video resolution for Twitter/X?

Use 1280x720 (720p) or 1920x1080 (1080p) for landscape videos. For vertical content, 720x1280 or 1080x1920 works well. Twitter's player scales content to fit, so 720p often provides the best quality-to-size ratio.

Does Twitter/X compress uploaded videos?

Yes, Twitter heavily compresses all uploaded videos. To minimize quality loss, upload at the highest quality source you can (1080p, high bitrate). Pre-compressing with medium quality from our tool helps avoid excessive double compression.
