Start with a 10 MB maximum instead of guessing at compression percentages.
Start with a target above, or open Full controls for a custom maximum and video settings.
Choose a local file. Review the selected maximum, any resolution cap and the advice before compressing.
Save the result and check its quality. Upload or attach it in your destination app yourself.
At a 10 MB ceiling, a one-minute clip has a total average bitrate budget of about 1.33 Mbps before container overhead and safety margin. A five-minute clip has about 0.27 Mbps. Audio uses some of that budget too, so longer footage needs more visual compromise.
Try a short clip and lower resolution when motion breaks into blocks. Tiny targets may be too small to process at the selected settings. Read the advice beside the action; there is no promise of lossless compression or guaranteed acceptance of every clip.
No. It is an upper bound; an encoded result can be smaller. SizeVideo verifies encoded output against the selected byte ceiling.
If the original fits and no video changes are selected, download it directly without uploading. An unchanged source keeps its original format.
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.
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.
