Frequently Asked Questions
What is the ideal image width for emails?
600px wide is the standard email content width that fits all email clients without horizontal scrolling.
How small should images be for email?
Under 1MB per image is recommended. Under 200KB per image is ideal for fast loading on mobile.
Why do images look different in Outlook?
Outlook uses Word's rendering engine which handles images differently. Use simple JPG images and avoid PNG with transparency for Outlook compatibility.
Should I use JPG or PNG in emails?
JPG is preferred for photos in email as it produces smaller files. Use PNG only when you need transparency.
Does the email preset compress the image too?
Yes, the email resize preset targets a 600px-wide output and applies compression to keep file size under 200KB.
