Compress Image for Email – Reduce File Size Without Quality Loss
Drop your images here
Select one image to compress, or multiple for batch ZIP download
Email providers reject attachments over 25 MB and clients load inline images slowly when they're too large. This tool compresses any image to email-friendly file sizes, typically under 500 KB, while keeping it looking sharp when opened.
A 12-megapixel iPhone photo straight from the camera is 4–8 MB. Attach three of those to an email and you're close to hitting attachment limits, and the recipient's inbox quota. Compressing to 200–500 KB per image removes this problem entirely.
This browser-based tool compresses JPG, PNG, and WebP images locally, your photos never leave your device. Adjust the quality slider to hit your target file size, then download and attach.
