A video compressor that never uploads your files
8disc compresses video with FFmpeg running directly in your browser through WebAssembly — or with native FFmpeg in the desktop app. Your file never leaves your device, so there is no upload wait, no queue and no privacy risk.
- 100% private — files are processed on your device, not on a server
- Free, with no watermark, no sign-up and no file limit
- Works offline in the desktop app for Windows and Linux
- Outputs MP4 (H.264 + AAC) that Discord plays inline

|---|---|---|
| Free | 10 MB | 8 MB |
| Nitro Basic | 50 MB | 50 MB |

Frequently asked questions
How do I compress a video to 8 MB for Discord?
Drop the video on this page, keep the 8 MB preset selected and press Compress. 8disc calculates the right bitrate and resolution so the output lands just under 8 MB, then lets you download the compressed MP4.
Is my video uploaded to a server?
No. Compression runs entirely on your device — in the browser through WebAssembly FFmpeg, or with native FFmpeg in the desktop app. Nothing is sent anywhere.
Which video formats are supported?
MP4, MOV, MKV, WebM, AVI and most formats FFmpeg can read. The output is always an MP4 with H.264 video and AAC audio, which Discord previews and plays inline.
Why compress to 8 MB if Discord's free limit is 10 MB?
Targeting 8 MB leaves a safety margin so the finished file never exceeds the limit, even when the encoder slightly overshoots. It also keeps older 8 MB-era servers and other platforms covered.
Will compression reduce my video quality?
Reducing file size always trades some quality. 8disc picks the best bitrate for the target size and only downscales resolution when needed, so the result stays as sharp as the size budget allows. Larger targets like 50 MB or 100 MB preserve much more detail.
Is 8disc really free?
Yes. There is no watermark, no account, no file-size cap and no daily limit. It is a local tool — your hardware does the work.
Is there a desktop app?
Yes. The desktop app for Windows and Linux uses native FFmpeg, can use your GPU for faster encoding and works fully offline.
