Why use WebP images?
WebP is a modern image format developed by Google that produces files typically 25–35% smaller than JPG and up to 80% smaller than PNG at the same visual quality. Smaller images mean faster page loads, better Core Web Vitals (especially LCP) and higher Google rankings — and every modern browser supports WebP.
How to convert an image
- Drag and drop your images or click to select them.
- Choose the output format — WebP, PNG or JPG — and the quality.
- Click Convert and download each file.
Which format should I choose?
- WebP – best for websites: small files, supports transparency.
- PNG – lossless, ideal for logos, screenshots and graphics with transparency.
- JPG – universal format for photos, best for email and print.

Image SEO checklist
- Use descriptive file names —
website-design-bhubaneswar.webpinstead ofIMG_2041.webp. - Write alt text that describes the image for visually impaired users and search engines.
- Serve the right size — never upload a 4000px photo to display at 800px.
- Set width and height attributes to prevent layout shift (CLS).
- Lazy-load images below the fold with
loading="lazy". - Use WebP for faster Largest Contentful Paint (LCP), a Core Web Vitals ranking factor.
