Standard posts: size and time
X documents a 512 MB maximum and 140-second duration for non-Premium uploads. The size preset does not trim a longer video. Shorten the clip separately if the standard-account duration is exceeded.

How to make your video smaller
- Choose a preset
Start with a target above, or open Full controls for a custom maximum and video settings.
- Select your video
Choose a local file. Review the selected maximum, any resolution cap and the advice before compressing.
- Download and review
Save the result and check its quality. Upload or attach it in your destination app yourself.
X Premium is a different subscription
X describes larger and longer uploads for Premium, with client-specific conditions. Those multi-GB ceilings exceed SizeVideo’s 1 GB output maximum, so use Full controls for a smaller target. An X subscription does not unlock SizeVideo Premium.
Questions about X (Twitter)
Is this also a Twitter video compressor?
Yes. X and Twitter refer to the same destination here, with one page and the same compressor.
Why not offer a multi-GB X Premium preset?
SizeVideo outputs at most 1 GB for Premium. A smaller output can still be useful for an X Premium upload, but this tool cannot encode to X’s larger published ceiling.
Can I change a preset?
Yes. Full controls opens the normal size ruler, custom maximum, resolution, frame rate and audio settings. Switching controls keeps the selected file. Presets set a maximum; the actual result can be smaller.
Will every video reach this size?
No. Very small targets can be unsuitable or fail for a long or detailed clip. Read the advice, try lower resolution or choose a larger maximum. Compression does not trim video or bypass a destination’s content and account rules.
