How to compress a video to 25 MB

  1. 1

    Drop in the video that is over the limit.

  2. 2

    There is nothing to configure: Flippy measures the clip's length and computes the exact bitrate that fits 25 MB, with a reserve for audio and container overhead.

  3. 3

    Download an MP4 that lands under the 25 MB bar, ready to send.

Why compress to 25 MB here

Exact-size math, no guessing

Flippy measures your clip's duration and computes the one bitrate that fills 25 MB: no compress-check-repeat loop, no preset roulette.

A real safety margin

The encode targets about 6% under the cap and reserves 96 kbps for audio and container overhead, so a file aimed at 25 MB actually clears a 25 MB limit.

A sensible resolution cap

Output tops out at 720p, because spreading a 25 MB budget across 4K pixels makes every one of them equally bad. Fewer, better pixels win at this size.

No watermark, no signup

Free for everyday use, MP4 out, and both files delete themselves from our servers within an hour.

The bitrate math behind the 25 MB button

File size is bitrate times duration: there is no other lever. Flippy converts your 25 MB budget into kilobits, takes 6% off the top for container overhead, hands 96 kbps to the audio, and gives the video stream every kilobit that remains.

A 25 MB budget buys around three minutes of decent-looking 720p video. Most email-bound clips run shorter than that, which is why 25 MB usually lands with quality to spare.

The fix for a long clip is length, not settings: trim to the part that matters, then compress. Sixty good-looking seconds beat five minutes of mush every time.

Questions people ask

How does Flippy hit exactly 25 MB?

Gmail and Outlook both draw the line at 25 MB: this page gets your video under it with room to spare. We divide your size budget by the clip's duration to get the precise bitrate, reserve a slice for audio and container overhead, and encode once to fit.

What happens to quality at 25 MB?

It depends entirely on length: a 30-second clip at 25 MB looks great, a 10-minute one won't; that's physics, not the tool. For long videos, trim first, then compress.
