Compress video to 100 MB

Roughly 8 min 46 sec of 720p video fits in 100 MB, or about 2 min 45 sec at 1080p. Set the target below and the bitrate is worked out for your clip's actual duration.

A practical target for direct file transfer and for platforms that re-encode anything you send them, where the goal is a manageable upload rather than a specific cap.

What fits in 100 MB

File size is bitrate multiplied by duration, so the only real question is how much bitrate 100 MB buys you for the length of your clip. These are the numbers the encoder works from.

Maximum runtime that fits in 100 MB, allowing 96 kbps for audio.

If your clip is longer than the row you want, trimming beats compressing. Cutting thirty seconds off the front costs you thirty seconds; forcing the same footage into half the bitrate costs you every frame.

Questions

How long a video fits in 100MB?

At 720p and a typical bitrate, about 8 min 46 sec. At 1080p, closer to 2 min 45 sec. High-motion footage compresses worse, so treat these as ceilings rather than promises.

Can any video be compressed to 100MB?

Almost any, but at some point the bitrate needed becomes low enough that the result looks poor. If your clip is long, trimming it costs far less quality than compressing it harder — a video twice as long needs half the bitrate to hit the same size.

Is my video uploaded?

No. The encoder runs in your browser through WebAssembly. Your file is read from disk and the result is written back to your downloads; neither is sent anywhere.
