About 8MB Video Compression
The 8MB cap is the classic Discord free-tier limit and still applies on many servers and bots that enforce strict attachment sizes. This tool re-encodes your video right in the browser, balancing resolution, bitrate and frame rate until the result fits under 8MB. Nothing is uploaded to a server — the file never leaves your device.
How to Compress a Video to 8MB
Add your video
Drop in an MP4, WebM or MOV file. H.264 MP4 gives the smoothest playback after shrinking.
Keep the Discord 8MB preset
The preset is already selected when the page loads. Switch to Discord 10MB or Custom if your limit differs.
Compress and share
Download the smaller file and attach it wherever the 8MB cap applies.
Frequently Asked Questions
Why do people still compress to 8MB?
The 8MB cap was Discord’s free-tier limit for years and remains the default expectation on many servers, bots and older platforms. Compressing to 8MB also guarantees the file fits anywhere stricter than 10MB.
How long can an 8MB video be?
Roughly 3–6 minutes at 480p or about a minute at 720p, depending on motion. The compressor automatically picks the highest bitrate that still fits under 8MB.
What quality can I expect at 8MB?
For short clips the result stays close to the original. Longer videos are scaled down and re-encoded at a lower bitrate; text and high-motion scenes soften first.
Is this 8MB video compressor free?
Yes, completely free with no registration. Processing happens locally in your browser, so there are no upload queues or file limits beyond your device memory.
