About This Tool
Email providers and corporate servers enforce attachment limits - Gmail stops at 25MB, and many workplace inboxes cap far lower - so a camera roll full of 5MB photos will bounce attachments back. This tool shrinks images for email so they attach and send instantly, with compression that runs entirely in your browser. Your photos stay private, and your recipient actually receives them.
How It Works
Three simple steps to get your optimized image.

Drag and drop or browse to select your image. JPG, PNG, and WebP files are supported.

Frequently Asked Questions
What is the attachment limit for sending images by email?
Gmail allows attachments up to 25MB total, while Outlook and many corporate servers cap at 10-20MB. Compressing photos to a few hundred kilobytes each keeps well under every limit.
How small should images be for email?
For a normal photo, anything under 500KB sends fast and looks great on a phone or desktop screen. Use the slider until the live preview looks right and the size drops under your provider's limit.
Does compression affect how the photo looks to the recipient?
Only slightly. At 500KB a photo still displays clearly on screens; the difference only shows at full zoom. The live preview shows you exactly what the recipient will see.
