Browser-Native Format Support
MP4 and WebM offer the most reliable browser-side compression. Some browsers can also open MOV, while other formats depend on local codec support.
Best supported input: MP4, WebM, MOV
Supported output: MP4, WebM
Some browsers may not decode AVI, MKV, FLV, or older codecs.

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.For an upload limit stated in KB or MB, confirm the portal’s own rule and inspect the downloaded file size. Do not assume a percentage reduction meets that limit. Preserve the original if document text, signatures or forms must remain usable.
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.
Does my video get uploaded to a server when compressing to 8MB?
No. The tool re-encodes your video entirely in your browser, so the file never leaves your device. You can even go offline in the middle of compression and it will still finish. Nothing touches a server, making it safe for private or confidential footage.
What bitrate should I use to keep a video under 8MB?
Plan for about 67 megabits in total. For a 60-second clip, aim for roughly 1,000 kbps video plus 96–128 kbps audio; halve that to around 500 kbps for two minutes. The tool can pick these automatically, or you can set them manually.
Can I compress MOV, WebM or MKV files to 8MB as well?
Yes. It accepts common inputs like MOV, WebM, MKV and AVI, then re-encodes everything to H.264 MP4 that plays in Discord's built-in player. The output is always MP4, so you avoid the playback problems some containers cause on mobile.
What resolution and frame rate should I choose for an 8MB Discord video?
For clips up to about 90 seconds, 720p at 30 fps looks clean at 8MB. Choose 480p for 2–3 minutes or fast motion such as gameplay. Stay at 30 fps instead of 60 — fewer frames free up bitrate that visibly sharpens the picture.
Compress video
Re-encode with a lower bitrate or resolution. Check playback, sound and the final size; a strict target may need further adjustments.
There is no guaranteed saving or exact target for every file. If the result is larger, some tools return the original; compare its format and size before sharing. For an upload limit stated in KB or MB, confirm the portal’s own rule and inspect the downloaded file size. Do not assume a percentage reduction meets that limit. Preserve the original if document text, signatures or forms must remain usable.
