Compress Image for Email Attachment

Email Attachment Size Limits

Gmail, Outlook, and Yahoo Mail all have attachment size limits (typically 25MB). If you're emailing multiple photos from a modern smartphone (each 5-12MB), you'll hit that limit fast.

This tool compresses your images to fit within email limits. Set a target file size (e.g., 2MB per image) and the tool will automatically adjust quality to hit that target. Preview the result before downloading. No photos leave your browser.
