Reduce image file size

Large images slow down websites, clog email inboxes, and eat storage. Reduce your image file sizes in seconds without visible quality loss.

Why it matters

Why reducing image size matters

Images typically make up 50-70% of a web page's total weight. Reducing image sizes directly improves Core Web Vitals and user experience.

Smaller images reduce CDN costs, storage bills, and mobile data usage. For high-traffic sites, the savings are significant.

Email providers reject large attachments. Gmail caps at 25 MB, Outlook at 20 MB. Compressing photos ensures your emails go through.

Recommended settings

For web images, quality 80 is the sweet spot. For email attachments, aim under 1 MB per photo.

FAQ

How much can I reduce an image's file size?

JPG photos typically shrink by 50-80% at quality 80. PNG files compress by 20-40%. Converting to WebP or AVIF provides even greater reductions.

Will reducing file size ruin my images?

At quality 75-85, the difference is invisible to the human eye. Only very aggressive compression (below 50) produces noticeable artefacts.

What is the best format for small file sizes?

AVIF produces the smallest files, followed by WebP, then JPG. For photographs, WebP at quality 80 is the best balance of size and compatibility.
