About this tool

When you need 25 MB

Gmail refuses attachments larger than 25 MB, and Outlook-style mailboxes have similar limits, so a phone video often has to shrink before it can be emailed.

Fitting the file under 25 MB

Aim a little under the limit: email adds overhead to attachments, so a 24 MB file is safer than one sitting right at 25 MB. This tool already leaves a margin. The tool aims for roughly 93 to 95 percent of the limit so the finished file does not tip over it.

Other size limits

Need a different ceiling? Use the related pages for other common upload caps, or the general FileHost.net Video Compressor for manual quality control.

Frequently asked questions

The tool divides 25 MB by the length of your clip to find the bitrate that fits, lowers the resolution if that bitrate would look blocky, then checks the result and re-encodes with a correction if it came out too large.

Attachments are re-encoded as text for transport, which makes them about a third larger. A file just under the limit can still be refused, so leave some headroom.

No. Encoding happens on your device with the WebCodecs API built into your browser, so the file never leaves it.

The tool tells you before encoding starts. About 3 minutes is the practical limit at 25 MB; trim the clip first with the Video Trimmer or pick a larger size.

You can force 1080p, 720p, 480p or 360p. The size target stays fixed, so a higher resolution simply means a lower bitrate per pixel.
