FAQ

What size should a website hero image be?
Website hero images are typically 1920×1080 pixels (16:9) for full-width layouts. For sections with text overlay, 1200×630 is common. Keep file size under 300KB by exporting as WebP.
What format is best for website hero images?
WebP is the best format for website hero images — it's 25–35% smaller than JPEG at the same quality, which directly improves page load speed and Core Web Vitals scores.
How do I resize an image for a website without losing quality?
Upload your image, set your target dimensions, and export as WebP at high quality. ResizeTh.is processes images client-side and outputs at high quality without unnecessary compression.
What image size is best for website SEO?
For SEO, prioritize file size over pixel dimensions. A 1200px wide WebP image under 150KB will load faster and rank better than a 1920px JPEG at 2MB. Use WebP format and appropriate dimensions for your layout.
