Frequently asked questions

What size should images be for email?

We recommend compressing images to under 500KB each for email. This ensures fast sending and receiving, even on slow connections. Our tool automatically targets this size while maintaining good visual quality.

Can I compress multiple images at once?

Yes! Drop as many images as you need and they'll all be compressed automatically. Download them individually or all at once as a ZIP file — perfect for sending photo batches via email.

Will Gmail and Outlook accept the compressed images?

Absolutely. Our compressed images are in standard JPEG format, compatible with every email client and web-based email service including Gmail, Outlook, Yahoo Mail, and Apple Mail.

Are my images private?

Yes. Your images are processed entirely in your browser. Nothing is uploaded to any server. The images never leave your device — we don't even have a server to upload to.
