How do I make a JPG small enough to email?

Convert it, then check the size of the WebP 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 WebP?

Most current browsers, phones and computers open WebP, but some email apps and older programs do not preview it. If you are not sure what the recipient uses, send a JPG or PNG instead.

Can I adjust the WebP output quality?

Yes. Review the converted WebP 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 JPG upload after conversion?

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

Should you email a WebP? Smaller files versus older mail apps

WebP shrinks a JPG photo, which sounds ideal for email, but the attachment still has to open on the other end. Current browsers and recent phones show WebP, yet some older desktop mail programs and picture viewers do not preview it, and the recipient may see only a file icon. If you do not know what the person reads mail on, the JPG you already have is the predictable choice.

WebP makes sense when you know the receiver can use it: a colleague who builds web pages, or a developer who asked for web-ready images. Then the default quality of 90 keeps photos close to the original, and dropping toward 75 trims the size further without an obvious change at normal viewing size.

For everyday sharing, keep the JPG and make it lighter instead: compress it to about 150 KB or cut its pixel dimensions. When a batch of pictures is going to someone unfamiliar with WebP, one PDF with a page per photo is a tidy single attachment that opens on practically any device.
