How do I make a BMP small enough to email?

Convert it, then check the size of the JPG result. If it is still over your mail service's attachment limit, lower the quality where the format allows it, or compress the result to a target size.

Will the recipient be able to open the JPG?

Yes — JPG opens in virtually every email client, phone and computer without extra software.

Can I adjust the JPG output quality?

Yes. Review the converted JPG result and adjust quality when that format supports it. Keep a higher setting for detail, or lower it when file size matters more.

What happens to my BMP upload after conversion?

The file is used only to create the requested JPG result and is automatically deleted after the temporary processing period.

Processed output — A for email photo and its Convert BMP to JPG for Email result, which looks the same, with both file formats shown.

Attaching a BMP? Convert it to JPG first

A BMP is about the least email-friendly picture there is, because it is normally uncompressed. Its size depends only on its pixel count, three bytes per pixel for a typical 24-bit file, so a 3000 × 2000 BMP weighs about 18 MB even if it shows a plain chart. Two or three of those fill a message quickly.

As a JPG, the same picture typically shrinks to a small fraction of that and opens in practically every mail app and phone gallery. The page starts at quality 90, a good level for screenshots and charts because color stays at full resolution along edges; photos can go lower, toward 75, usually without a visible change at normal viewing size.

The converter keeps the original pixel dimensions, so a very large BMP stays large in pixels. Shrink the dimensions if the recipient only needs to look at it, or set an exact size such as 200 KB for an upload form. If every pixel must stay exact, for example measurement images from lab equipment, BMP to PNG is lossless and usually much smaller than the BMP.
