Your videos are compressed right in your browser - nothing gets uploaded to our servers or anywhere else. This means faster processing, complete privacy, and no file size limits from upload restrictions.
Twitter / X has a file size limit of 512MB. To ensure successful uploads, we recommend compressing your video to slightly below this limit. Our tool can help you target the exact file size you need.
Twitter / X works best with MP4 format using H.264 codec. This combination ensures compatibility across all devices and smooth playback.
The most common reason is file size exceeding 512MB. Other issues include unsupported formats or resolutions. Compress your video and ensure it's in MP4 format before uploading.
Twitter / X may apply its own compression after upload, which can reduce quality. By compressing your video beforehand with our tool, you have full control over the quality settings and can often achieve better results than automatic platform compression.
Twitter / X supports up to 1080p. We recommend 1080p for best quality, though 720p is often sufficient for mobile viewing and results in smaller file sizes.
