Tips

FAQs

What if the image still looks bad at 1MB for email?

Lower the quality target slightly and try again. For very small targets, some quality loss is inevitable.

Does compression change image dimensions?

No — compression reduces file size without changing pixel dimensions. Use resize to change dimensions.

Can I compress to exactly 1MB for email?

The tool targets under 1MB for email. The actual output may be slightly smaller than 1MB for email.
