Is this video compressor free?

Yes — Morphix is 100% free, with no signup, no watermark, and no upload limits from us.

Are my videos uploaded to a server?

No. Compression runs in your browser via ffmpeg.wasm. Your video never leaves your device.

How do I compress a video to 8MB for Discord?

Pick the 'Discord (8MB)' preset. Morphix re-encodes at a lower bitrate and resolution to fit under Discord's free-tier 8MB attachment limit.

What formats does the compressor support?

MP4, MOV, MKV, WebM, AVI, and most common video files. Output is always MP4 (H.264 + AAC) for universal playback.

Video Compressor — Compress MP4 in Browser

Compress video online — without uploading

Most video compressors upload your file to a server, queue it, and email you the result. Morphix doesn't. Compression runs entirely in your browser with ffmpeg.wasm, so your video never leaves your device — no signup, no watermark, no per-file size caps from us.

Compress MP4 to 8MB for Discord

Discord's free tier caps attachments at 8MB. Pick the Discord (~8MB) preset and Morphix re-encodes at a lower bitrate and resolution (max 720p) to hit that target. For longer clips, try the Small file preset and trim the video first.

Which preset should I pick?

High quality — keep original resolution, modest size reduction. Best for archival.
Balanced — good default for web, email, and social uploads.
Small file — significant size cut for chat, WhatsApp, and quick shares.
Discord (~8MB) — aggressive compression targeting Discord's free-tier limit.
