Convert HEIC to JPG for Email Attachments

HEIC attachments cause problems in most email clients. Gmail and Outlook on Windows do not display HEIC inline — recipients see a generic file icon instead of the photo, and they must download it and install a codec to view it. Many corporate email filters also strip or quarantine unknown file types.

JPG attachments display inline in every major email client: Gmail, Outlook, Apple Mail, Yahoo Mail, and mobile clients on both Android and iOS. Using JPG ensures your photos display correctly for every recipient, regardless of their operating system or email client.

Convert your HEIC photos to JPG here before attaching them to your email. At quality 85–90%, a typical iPhone photo goes from ~3 MB HEIC to a ~2–4 MB JPG — still clear and high-resolution but universally compatible.
