Frequently asked questions about optimization
Does compressing an image hurt visual quality?
It depends on the method. Lossless compression doesn't alter a single pixel — it just reorganizes the data internally. Lossy compression (like JPG) removes details the human eye barely notices. With the right settings, the visual difference is practically imperceptible while the file gets 40–80% smaller.
What is the ideal image size for a website?
For content images (banners, photos), aim for under 150KB. For thumbnails and secondary images, under 50KB. Never use images larger than 500KB without a very specific reason. The WebP format helps significantly in reaching these sizes.
Does Google penalize sites with heavy images?
Not directly, but heavy images lower your PageSpeed Score, which is a ranking factor. Slow sites also have a higher bounce rate, which indirectly hurts SEO. Google explicitly recommends using WebP and proper compression.
Does WebP work in all browsers?
Yes. WebP is supported by more than 97% of modern browsers, including Chrome, Firefox, Safari (since 2020) and Edge. For sites that need to support very old browsers, JPG can still be used as a fallback with the HTML picture tag.
