Why compress your images?
Faster websites
Smaller images load faster. A 1-second delay in page load costs 7% conversions. Google ranks faster pages higher.
Better SEO
Page speed is a direct Google ranking factor. Compressed images improve Core Web Vitals scores.
Lower bandwidth costs
Images are 60–65% of an average webpage weight. Cut them in half, cut your CDN bill in half.
Mobile performance
Mobile users have limited bandwidth. Smaller images mean faster loads and less data usage for your visitors.
EXIF data removed
Compressed images strip GPS coordinates, camera model, and other metadata from your photos automatically.
Higher conversions
Amazon found every 100ms of latency costs 1% in sales. Fast-loading images keep users engaged.

Format guide
The most advanced image format available. Based on the AV1 video codec. Delivers 50–90% better compression than JPEG at identical visual quality. Supported in Chrome 85+, Firefox 93+, Safari 16+.
The web standard for photos. JPEG compression works by analyzing 8×8 pixel blocks and discarding visual detail your eye won't notice. At 80–85% quality, files are 60–80% smaller with no perceptible loss.
Lossless format — every pixel is preserved exactly. Best for logos, screenshots, UI elements with transparency. PressImg reduces PNG size by converting to indexed color (PNG-8), typically achieving 60–70% savings.
Google's modern format. Supports both lossy and lossless compression. Delivers 25–35% smaller files than JPEG at equivalent quality. Supported in Chrome, Firefox, Safari 14+, and Edge.
