How do I compress a video to under 10MB for email or Discord?

Open AnyTool's Compress Video to 10MB tool, drop in your clip, and it computes a target bitrate from the video's duration and re-encodes to H.264/AAC MP4 in your browser so the result reliably lands under 10MB — small enough for email attachments and free Discord. If it overshoots it auto-tightens and retries. The file is never uploaded; no watermark, no sign-up.

  • Target-bitrate encoding that lands under 10MB
  • Auto-retry at a lower bitrate if it overshoots
  • Fits email attachments and free Discord (10MB)
  • 100% in your browser — no upload, no watermark

What is

Target-size video compression

Target-size compression chooses a video bitrate from the clip's duration so the encoded file lands at or under a chosen size (here 10MB), rather than aiming at a quality level with unpredictable bytes. A small headroom and auto-retry ensure it stays under the cap.

Frequently Asked Questions

Yes — the tool sizes the bitrate to land under 10MB and auto-retries lower if it overshoots.

It keeps a small headroom below the cap, so the result fits email and free Discord every time.

No — it is compressed entirely in your browser with a self-hosted engine.

The file never leaves your device and there is no watermark, sign-up or monthly quota, unlike most online compressors.

Email attachments and the free Discord upload limit, which is 10MB.

It is the safest size for sending a short clip without a paid plan or cloud link.

Detailed Explanation

Methodology

How Compress Video to 10MB Works

AnyTool compresses a video to under 10MB entirely in the browser with a self-hosted single-threaded ffmpeg.wasm engine (bundled, no CDN). It probes the clip's duration and computes a target video bitrate so the encoded file lands under the 10MB cap (with a headroom margin), then encodes capped single-pass H.264 (libx264, -maxrate/-bufsize) with AAC audio, yuv420p and +faststart. If the result still overshoots, it automatically retries at a lower bitrate, so the file reliably fits email attachments and the free Discord 10MB limit.

  • Runs client-side — the video is never uploaded
  • Bitrate computed from duration to land under 10MB
  • Auto-retry at a lower bitrate on overshoot
  • H.264/AAC MP4 + faststart, accepted everywhere
  • Fits email attachments and free Discord (10MB)
  • Self-hosted engine — no CDN, no watermark, no sign-up
Privacy & Security

Privacy vs Cloud Compressors

8mb.video, FreeConvert, Clideo and VEED upload your file to a server; many watermark or cap the free tier and only delete the file later. AnyTool encodes locally with a bundled engine, so the file never leaves your browser, there is no watermark, sign-up or quota, and it works offline after the first load.
