Compress Images for Email

Email providers often reject attachments that are too large, and big images make messages slow to send. Compressing your photos to WebP shrinks them dramatically so they attach and send without a problem.

Frequently asked questions

What size should an email image be?
Keeping each image under a few hundred KB is a safe target. Compressing to WebP usually gets you well below common attachment limits.
Will the recipient be able to open WebP?
WebP opens in every modern browser and most photo apps. For an older recipient, a compressed JPG is the safest choice.
Can I compress several photos for one email?
Yes. Add multiple photos and download them all in a single ZIP to attach at once.
Is it private?
Completely. Your photos are compressed in your browser and never uploaded.
