Why image compression matters for websites
Page speed directly affects user experience and search rankings. Images are typically the heaviest assets on a web page.
Compressing them is one of the fastest wins for site performance.
Web images and loading speed
Every kilobyte counts when users are on slow connections or mobile data. Compressing images for the web ensures pages render quickly regardless of connection speed.
The Balanced preset targets a sweet spot where file size drops significantly but the image still looks sharp.
Best format for web
JPG works for photographs with lots of color. PNG is best for icons, logos, and images needing transparency.
WebP offers smaller files than both for browsers that support it.
Integration with CMS platforms
After compressing your images here, upload them to WordPress, Squarespace, Wix, or any CMS.
No plugins or additional tools required — just smaller files from the start.
