Choose a maximum size. We balance the bitrate, resize if needed, then check the finished file.
Preview it, download it, and send it your way. No watermark. No account standing in the way.
No video uploads, no tracking scripts, no signup.
The only thing getting smaller is your file.
Eight decimal megabytes contain 64 million bits. Before overhead, that gives a 30-second video about 2.13 megabits per second for picture and sound; a two-minute video has only about 0.53. Longer clips therefore lose more detail at the same target.
Use Auto resolution for a balanced starting point. Keep sound for a conversation; turn it off for a silent screen demonstration to leave more of the budget for the picture. SmallerKit never removes sound unless you turn off Keep audio.
This page starts at 8 MB but does not assume any platform still uses that limit. Check your destination. When compression cannot make the entire clip fit, increase the target or shorten the source video elsewhere.
Everything you should know before
making something smaller.
No. SmallerKit uses decimal megabytes: 8 MB is 8,000,000 bytes. A mebibyte is larger. The result is checked against the decimal target, with extra headroom used during encoding.
No video data is uploaded by this app. The browser reads the file locally and encodes the result on your device. There are no analytics scripts, accounts or remote processing services in this version. Your web host can still log ordinary page requests.
Input depends on what your browser can play. MP4, MOV and WebM are common containers, but the codec inside matters. For output, SmallerKit checks for H.264 MP4 support first and otherwise offers WebM. It never disguises one format with another extension.
This version records at playback speed, so allow roughly the length of the clip for each attempt, plus preparation. It may retry twice if the first file is over target. Keep this tab visible and your device awake; switching away stops the attempt to avoid an incomplete result.
This build has no payment system, signup or watermark. For predictable memory use, it accepts one video at a time, up to 250 MB and 10 minutes. Browser resources still vary; a file within those limits can fail on a low-memory device.
Not exactly. Re-encoding is lossy and can change resolution, frame rate, colors or audio. This version targets standard SDR clips, not HDR mastering. Preview the result and retain your original. Captions, chapters and extra audio tracks are not preserved.
