How It Works
Three steps to get started
01
Upload your video
MP4, MOV and WebM all work. Drop it in or choose it from your device.
02
Set size and resolution
Pick the target size and whether you want 1080p, 720p or 480p — the trade you are making is visible before you commit to it.
03
Download
The compressed file comes back ready for whatever refused the original.
Why 8MB
The limit
that keeps stopping you.
8MB is Discord's free upload ceiling, and a common cap on forms, ticket attachments and email. Compressing to a target beats compressing by feel, which is how you end up at 8.4MB twice in a row.
- Target a size, not a guess
- 1080p, 720p or 480p
- MP4, MOV and WebM in

Frequently Asked Questions
Yes — this one is a hosted tool, so the file you choose is sent to the service that runs it and processed there. Most Zight tools work the other way round and never upload anything; the note under the widget tells you which kind you are on.
It is Discord's upload ceiling on the free tier, and a number that turns up on plenty of web forms and ticketing systems too. It is not a video standard — just the most common wall people hit.
Some, and how much depends on how far it has to travel to reach the target. Screen recordings survive it well because most of the frame is static; fast-moving footage suffers more, which is where dropping to 720p helps more than squeezing the bitrate further.
Yes — the MP4 compressor and the general video compressor both run entirely in your browser. They compress by quality rather than to a size target, so use those when the file simply needs to be smaller and this one when it has to clear a specific number.

altogether.
A Zight link plays anywhere without an upload limit — no compressing to fit somebody else's ceiling.
