MPEG → Twitter / X
Compress MPEG for Twitter / X
Compressing MPEG for Twitter / X comes down to three constraints: Twitter / X's 512 MB cap, its 1920:1200 resolution ceiling, and the need to output MP4 H.264 for reliable inline playback. MPEG source files are typically 720×480 (DVD) or 352×240 (VCD) at around 300 MB per minute — right at Twitter / X's 500 MB target. We calculate a per-clip bitrate budget from your duration, subtract 128 kbps for audio, and allocate the remainder to H.264 video at the highest quality that fits. MPEG-1 and MPEG-2 are 3-5× less efficient than H.264; the transcode alone recovers most of the file size before bitrate targeting. Twitter / X does not play MPEG inline, so this page does a format conversion (MPEG → MP4 H.264) plus the size compression in a single pass.

How to compress MPEG for Twitter / X
- 1Drag your .mpeg file onto the upload zone above (or browse to it).
- 2Twitter / X is already selected — we'll target 500 MB to stay safely under the 512 MB cap.
- 3Optionally trim to a highlight clip or switch to H.265 for 30-50% smaller files at the same quality.
- 4Download the compressed MP4 and share it on Twitter / X. Source file auto-deletes from our servers after 1 hour.
What to know about MPEG → Twitter / X
- MPEG-1 and MPEG-2 are 3-5× less efficient than H.264; the transcode alone recovers most of the file size before bitrate targeting.
- Resolution is kept at up to 1920p when the bitrate budget allows.
- Trim to the highlight before you compress — every 10 seconds you cut gives remaining frames more bitrate to work with.
- Twitter / X's 500 MB target leaves a 5% safety margin below its 512 MB hard cap, so platform-side rejection is never an issue.
The compression math
A 1-minute MPEG at 720×480 (DVD) or 352×240 (VCD) = ~300 MB. Twitter / X's 500 MB target minus 128 kbps audio = ~69777 kbps video budget. H.264 at that budget kept at up to 1920p when the bitrate budget allows produces a file at the target size that plays inline on Twitter / X.
About MPEG files
MPEG is a family of older video formats including MPEG-1 (used in VCDs) and MPEG-2 (used in DVDs and TV broadcasts). These formats use compression technology from the 1990s that is far less efficient than modern H.264. A DVD-quality MPEG-2 file is typically 3 to 5 times larger than an equivalent MP4. CompressYourVideo.com converts MPEG files to compressed MP4 with H.264 encoding, reducing file size by 50 to 80% while maintaining visual quality. This is especially useful for DVD rips, old camcorder footage, and VHS captures that were digitized in MPEG format. The compressed MP4 output is compatible with every modern device and platform.
About Twitter / X
Compress videos for Twitter/X. Twitter's free tier allows up to 512MB, but videos must be under 2 minutes 20 seconds. X Premium users get 16GB and longer duration.
