How to resize an image for email
Large camera photos can be several thousand pixels wide even though most email content columns display at roughly 600 pixels. Reducing pixel dimensions usually delivers the biggest file-size improvement while keeping the email readable and fast.
JPG is usually best for photographs. PNG is useful for logos, diagrams, and transparency. WebP can be smaller, but verify that the email platform and recipient applications support it. For newsletters, retain a high-resolution source separately and test the final message on desktop and mobile.
