Type the size you need — 18 MB for email, 19 MB for Discord — and VidSmaller two-pass encodes your video to land just under it. Or pick constant quality (CRF), a bitrate ceiling, or just scale 4K down to 1080p. 33 input formats in; H.264/H.265 in MP4, MKV, WebM or MOV out. Encoding runs on our servers, so a Chromebook handles a 4K file as fast as a workstation. Never a watermark, on any plan. Files auto-delete after the job. No install, no account to try.
