How do I make a PNG 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 PNG upload after conversion?

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

Emailing a PNG as WebP: transparency travels, previews may not

A WebP made from a PNG keeps the transparent background, which helps when you send a logo, sticker or cut-out product to someone who will place it on their own design. The catch is the recipient's software. Web browsers and recent phones open WebP, but some older mail programs and image viewers show it only as an unknown attachment.

If the person is a designer or developer asking for web-ready files, WebP is a sensible thing to send; choose Lossless mode for logos and line art so edges stay exact. If the picture just needs to be seen, attach the original PNG, or make a JPG with a fill color when a small file matters more than transparency.

Keep the attachment light either way. Exports from design apps are often sized for very large screens, so scale them down to what the recipient needs before converting. A set of brand assets can also go first as one PDF proof sheet for review, followed by the separate WebP files once they are approved.
