Bigger files take longer — your CPU does the work, privately.
Why 8 MB?
The 8 MB target is the classic Discord free-upload limit and a common cap on older forums and chat tools. Free Discord has moved on twice since — to 10 MB, and to 20 MB in August 2026 — but many guides, servers and other platforms still expect 8 MB, so it stays the safe universal target for a small clip.
The compressor calculates the exact bitrate to land under 8 MB from your clip’s length — short clips keep good quality, while longer ones benefit from trimming first.
How long a video fits in 8 MB — and at what quality
8 MB × 8 × 1,048,576 bits × 0.96 ÷ 12 s = 5,368 kbps in total; − 128 kbps of AAC audio = 5,240 kbps of video. Same constants on every row, taken from the compressor’s code (0.96 = 4% left for the MP4 container).
| Clip length | Total bitrate (kbps) | Video bitrate (kbps) | Max short side |
|---|---|---|---|
| 12 s | 5,368 | 5,240 | No cap (source kept) |
| 13 s | 4,955 | 4,827 | 1080 px |
| 24 s | 2,684 | 2,556 | 1080 px |
| 25 s | 2,576 | 2,448 | 720 px |
| 57 s | 1,130 | 1,002 | 720 px |
| 58 s | 1,110 | 982 | 480 px |
| 4 min 11 s | 256 | 128 | 480 px |
| 4 min 12 s | 255 | 127* | 480 px |
- * 8 MB · 4 min 12 s: 128 kbps of audio would take over half the budget, so video still gets half (127 kbps); the planned file (7.7 MB) eats into the 4% margin but stays under 8 MB.

Frequently asked questions
How do I compress a video to 8 MB?
Drop your video, keep the 8 MB preset selected, and download the result. The tool targets just under 8 MB so it uploads reliably.
Can I hit an exact size like 8 MB?
Yes — the compressor sets the bitrate from your clip length to land under the target, with a small safety margin so it never goes over.
My clip looks soft at 8 MB — why?
Eight megabytes is very little for a long or high-motion video. Trim to the key moment, or use a larger target — 10 MB, Discord’s current 20 MB free limit, or WhatsApp’s 64 MB — if your destination allows.
Is anything uploaded?
No — it all runs in your browser. Your video stays on your device.
