Why Compress Images for Email?
Most email clients limit attachment sizes to 10-25 MB, and embedded images should ideally be under 200 KB each for fast loading. Our compressor optimizes images specifically for email — reducing file sizes by up to 80% while keeping them sharp and readable in every email client.
