Email image workflow
How to compress images for email
Smaller email images open faster on mobile connections and are less likely to hit attachment limits. Choose a format and dimensions that match the message.
Compress an image privatelyUseful for newsletters, customer support, sales teams, and anyone sending image attachments from a phone or laptop. PixPact processes images locally in your browser; no image upload is required.
A practical workflow
- Decide whether the image is an attachment or an inline newsletter asset; the destination determines the right dimensions.
- Use JPEG or WebP for photos, PNG for transparent diagrams, and keep the longest edge near the size people will actually see.
- Compress the image locally, check the saved percentage and result dimensions, then download the ready file.
- Send a test email to a phone and a slower connection before using it in a campaign or customer message.
Before you publish
- Keep important text readable
- Avoid huge original camera dimensions
- Use descriptive attachment names
- Test dark mode and mobile rendering
Common questions
What is a good email image size?
It depends on the template, but a useful rule is to export near the largest rendered width and avoid sending a camera-original image when a smaller copy will do.
Does PixPact upload email images?
No. PixPact performs the compression in your browser, and you choose when to download the result.
