WEBP image compressor – reduce file size without losing quality

Why compress WEBP images?

• Much smaller files and faster page loads.
• Better user experience on mobile and slow connections (3G/4G).
• Improved SEO by boosting Core Web Vitals (LCP, FID, CLS) on key pages.
• Perfect for blogs, landing pages, portfolios and e-commerce product photos.

When should I compress WEBP instead of converting?

If you already use WEBP in your website or app and only need to reduce file size, compression is usually enough. If you want even smaller files, you can also try converting your images to modern formats like WEBP or AVIF using our image converter.
