No uploadFree toolBrowser-based
Can I compress a video to exactly 1MB?
Only very short clips (a few seconds) can fit in 1MB. Trim the video first, then compress with low resolution and bitrate.
What quality can I expect at 1MB?
Expect low resolution (240-360p) suitable for previews and short demonstrations, not high-quality viewing.
Are videos uploaded?
No. LessMB compresses videos locally in your browser session.
