Email-friendly image size guidance
- Default starting point: 200 KB for general email attachments and inline images.
- Try a lower target such as 100 KB for signatures, small banners, or messages with multiple images.
- Email clients and recipients can handle image size differently, so use the final file size as practical guidance rather than a universal rule.
- Large phone photos may need both compression and dimension reduction before they are easy to send.
There is no single official email image size requirement. This page starts at 200 KB as a practical balance between smaller messages and usable visual quality.
Why an image may not meet the requirement
The source image may be too large to reach a very small file-size target without major quality loss.
The source image may be too small for the selected output dimensions.
The selected requirement may need a different image ratio.
Frequently asked questions
What size should an image be for email?
Use the smallest size that still looks clear for the message. A 200 KB target is a practical starting point for many email images, while 100 KB can be better for signatures, banners, or messages with several images.
Is there a universal email attachment image limit?
No. Email providers, clients, and recipients can apply different message and attachment limits. This page provides a practical reduction workflow, not an official requirement for every email service.
Should email signature images be smaller than photo attachments?
Usually yes. Signature logos and small banners often work better as compact files because they load with every message and do not need the same detail as a full photo attachment.
Will reducing an image for email change its dimensions?
It can. To approach the target size, the tool may reduce quality, dimensions, or both depending on the source image.
When should I use the website page instead of the email page?
Use the website page when the image is meant for online publishing and page performance. Use the email page when the image is being sent as an attachment, signature image, or email banner.
Does ImageSize store uploaded images?
Images are processed for the active request. No account is required, and the product does not include an image library or user gallery.
