LimitFix

Compress a video to send by email

Most email providers stop at 20 to 25 MB per message, including encoding overhead. LimitFix fits your video into 13 MB, a size that gets through virtually everywhere.

How big can an email attachment be?

Email providers usually limit the whole message to somewhere between 20 and 25 MB, and attachments grow by about a third when they're encoded for sending. 13 MB is a safe size for virtually every provider; if you know the recipient and sender both use Gmail, you can go up to 18 MB.

Sending to a work address

Company mail servers often set stricter limits than consumer providers. If a message bounces, try again with a smaller custom size — 10 MB is a common corporate cap.

Questions people ask

What size should a video be for email?

Under about 13 MB is safe for almost any provider once encoding overhead is added. If both sides use Gmail, up to 18 MB works.

Why did my email bounce even though the file was under 25 MB?

Attachments grow by about a third when encoded for sending, and the recipient's server may have a lower limit than yours.

Will the video still look good?

LimitFix picks the highest resolution the size budget can render cleanly instead of keeping full resolution and smearing everything. Short clips usually stay in 1080p or 720p; long videos drop to a lower resolution so they stay sharp rather than blocky.

Is my video uploaded anywhere?

No. LimitFix compresses the video inside your browser, on your own device, so the file isn't uploaded to us or anyone else. The only exception is the optional cloud processing for Pro users, which you have to choose explicitly; those files are deleted automatically after processing.
