Frequently Asked Questions

Why should I compress images for my website?
Image file size is the #1 factor affecting web page load speed. Compressed images improve Core Web Vitals scores, SEO rankings, and user experience. Google recommends keeping images under 100 KB when possible.
What image format is best for the web?
WebP offers the best compression for web (25-35% smaller than JPEG). JPEG is great for photos and has universal browser support. PNG is best for images needing transparency or with sharp text.
Will compressing images hurt their quality?
Modern compression algorithms can reduce file sizes by 60-80% with virtually no visible quality loss. Our tool uses smart compression that preserves visual quality while achieving the target file size.
What size should website images be?
Content images: 800-1200px wide. Hero banners: 1200-1920px wide. Thumbnails: 300-400px wide. Always serve the appropriate size for the display area — don't load a 3000px image in a 600px container.
