Twitter Video Requirements
Twitter accepts MP4 videos with H.264 video codec and AAC audio. Maximum file size is 512MB with a duration limit of 2 minutes 20 seconds (140 seconds).
While Twitter accepts large files, smaller optimized videos upload faster and preserve more quality after Twitter's processing. Aim for 15-50MB for typical content.
This converter outputs Twitter-optimized MP4 files that meet all platform requirements. Processing happens entirely in your browser for complete privacy.
Optimizing for Twitter Quality
Twitter re-encodes every uploaded video, which can reduce quality. To minimize quality loss, upload videos that already meet Twitter's output specifications.
Use 1080p resolution at 30fps with a bitrate around 5-6 Mbps. This matches Twitter's typical output quality and reduces re-encoding artifacts.
Avoid uploading pre-compressed or heavily edited videos. Each compression cycle degrades quality. If possible, export fresh from your video editor.
Twitter Video Best Practices
Keep videos short and engaging. Twitter users scroll quickly — grab attention in the first 3 seconds.
Add captions or text overlays for silent viewing. Most Twitter users watch videos muted.
Optimize thumbnail frames since Twitter uses the first frame as the preview. Add a compelling opening frame.

Open ConverterVideo to MP4 (Twitter) FAQs
What are Twitter's video upload limits?
Twitter allows videos up to 512MB and 2 minutes 20 seconds long. Resolution up to 1920x1200 (or 1200x1920 portrait) is supported. Videos must be MP4 with H.264 codec.
Why does Twitter reduce my video quality?
Twitter re-encodes all uploaded videos. Starting with a well-optimized source file helps minimize quality loss. Use 1080p, H.264, and avoid pre-compressed content.
What's the best resolution for Twitter videos?
Use 1280x720 (720p) for most content or 1920x1080 (1080p) for high-quality content. Higher resolutions get downscaled anyway and waste file size.
How do I make my video loop on Twitter?
Twitter automatically loops videos under 60 seconds. For seamless loops, create your content with the end matching the beginning, then upload as MP4.
Should I use 30fps or 60fps for Twitter?
Twitter supports up to 60fps but 30fps is recommended. Higher frame rates increase file size without significant benefit since Twitter may re-encode to 30fps anyway.
Can I post vertical videos on Twitter?
Yes, Twitter supports portrait videos up to 1200x1920. Vertical videos perform well for mobile users scrolling their timeline.
