Questions about email image optimizer
What image size is best for email?+
For normal viewing, a 1600–1920px long edge and 75–85% JPEG quality usually looks sharp while remaining manageable.
Can I compress many email photos together?+
Yes. Process them as a batch and download a ZIP, or download each image separately.
Are email photos uploaded?+
Yes. CompressMint processes images locally in your browser. Your photos are not uploaded to our servers, and refreshing the page clears the working session.
