Compress images for email attachments
Email providers often limit attachments to 10–25 MB. Compresso shrinks photos locally so they fit — without sending your images to a compression service.
How it works
- Open Compresso.
- Load the photo.
- Download the smaller file and attach to your email.
Common questions
- Will quality be acceptable?
- Compresso uses modern formats (WebP/AVIF) and never-bigger guarantee for lossy output.
