Compress Video to 8MB

8MB is a hard ceiling some school portals, job forms and older upload boxes still enforce. It is not Discord’s free limit. Discord’s help center lists 20MB for non-Nitro accounts as of August 2026. Use this page when the form itself says 8MB. A 30-second clip can look fine; a long video will not.

Hit an 8 megabyte cap for portals and forms that still reject anything larger.

When you actually need 8MB

Discord’s free cap moved to 20MB in August 2026. An 8MB file is for the form that still says 8MB, not for Discord.

The budget is tight. Trim before you encode. The table on this page shows how fast the picture has to shrink as the clip gets longer.

The cap is hard. If the encoder cannot land under 8MB it retries once at a lower resolution and, if it still misses, stops with a clear failure instead of handing you an oversized file.

8MB is a target you chose or a form demanded. It is not a platform rule we are attributing to Discord.

Read the table before you encode

At 8MB, a 15-second clip still has a healthy bitrate. A 10-minute clip does not. If the planner drops to a very small picture, trim the clip or ask whether the form can take 10MB instead.

The numbers are the same formula the compressor uses. They are a plan, not a lab measurement of one sample file.

What fits in 8 MB

Planning estimate from Slimvid’s size formula: 97% of the byte cap, a small audio reserve, then a lower resolution when the video bitrate would look bad. It is not a measured encode of one clip. Motion, codec and audio change the file.

FAQ

8MB video FAQ

Is 8MB still a real limit?
Yes on some LMS, job and government upload forms. Discord’s free accounts are at 20MB as of August 2026. Use the Discord page for Discord.
Will the result be 8MB or less?
Yes. 8MB is a hard cap. Very long clips need a trim to stay watchable. The duration table shows the bitrate you actually get.
How do you calculate the bitrate?
Target bytes times 8, divided by duration, with about 3% held back and a small share reserved for audio. The rest is the video bitrate. Resolution steps down when that bitrate cannot hold a sharp picture.
Can I do this on a phone?
Yes. Phones use the hardware encoder. Huge 4K files may still need a shorter range.
