What is the best image format for websites?

WebP is currently the best all-around image format for websites. It produces files 25-35% smaller than JPEG at equivalent quality, supports transparency, and is supported by all modern browsers. Use WebP as your default, with JPEG fallback for older browser support.

How do I reduce image file size without losing quality?

Three steps: First, resize the image to match its display size on your website (don't upload 4000px images for 800px displays). Second, convert to WebP format. Third, use compression — most images can be compressed 60-80% without visible quality loss. Use free tools like ToolsSewa's Image Resizer and Image Converter.

Do images affect SEO?

Yes, significantly. Large, unoptimized images slow down your page, which hurts your Google ranking since page speed is a confirmed ranking factor. Additionally, Google's Core Web Vitals (especially Largest Contentful Paint) are directly affected by image loading times. Properly optimized images improve both speed and search visibility.

How can I optimize images for free?

Use ToolsSewa's free Image Resizer to resize images to the correct dimensions, then use the Image Converter to convert them to WebP format. Both tools run in your browser, require no signup, and produce optimized images ready for web use.
