What is the maximum email attachment size for Gmail?

Gmail allows attachments up to 25MB per email. However, images over 5MB may not load quickly on mobile. Compress photos to under 1MB each for reliable email delivery.

Why is Outlook rejecting my image attachments?

Outlook and corporate Exchange servers often enforce limits as low as 5-10MB total per email. Compressing images to under 500KB each ensures reliable delivery to Outlook users.

Will my compressed images look good in email clients?

Yes. At 80-85% JPEG quality, images appear identical to the original on email screens. Email clients render at 72-96 DPI, so high-quality compression is invisible to recipients.

Is it safe to compress private photos for email online?

Completely safe with MinifyPic. All compression runs in your browser locally. Your photos never reach any server - they stay entirely on your device throughout the process.

Can I compress multiple email attachments at once?

Yes. Upload all photos you want to attach, compress in one step, and download as a ZIP. Extract and attach the individual compressed files to your email.
