Compressing images is one of the highest-impact things you can do for page load speed and email deliverability. Done right, viewers can't tell the difference.
Two axes of compression
Resolution (pixels): shrink 4032×3024 down to 1600×1200 for the web and you often lose 4× the size instantly. Encoding quality: re-encode at 70–80% quality and get another 40–60% off, still with no visible loss.
The default quality choice
Our compress-image tool re-encodes at a smart default that keeps photographs sharp on screen while dropping size by roughly half. For hero images and marketing photos, this is the sweet spot.
FAQ
Do I lose detail?
At default settings, detail loss is imperceptible on screen. If you plan to print at large sizes, keep the original as a backup.
Is WebP better than JPG?
For similar quality, WebP is typically 25–35% smaller. All modern browsers support it.
