How to Reduce Image Size for Email
Email is one of the fastest places to hit file-size limits. This guide helps you shrink images for attachments without turning them into unreadable thumbnails.
Example input
A phone photo or screenshot that is too large to send comfortably.
Expected output
A smaller image that still looks clear enough for inbox viewing.
Step by step
How to follow this workflow
Upload the image and start with moderate compression settings.
Reduce dimensions if the image is much wider or taller than it needs to be for inbox reading.
Download the optimized file and confirm it still looks clear at normal email viewing size.
If you still need more savings, export a JPG from PNG where transparency is not required.

FAQ
Questions people still ask after reading
Why are screenshots so large in email?
Screenshots can stay in PNG form with large dimensions, which makes them heavier than many email workflows need.
Should I use JPG for email?
