Yes! You can drag and drop multiple files or use the "Add more" button to select additional images. All files will be converted to your chosen format simultaneously, and you can download them all at once as a ZIP archive.
Why should I convert images to WebP or AVIF?
WebP and AVIF are next-generation image formats that deliver 25-50% smaller file sizes compared to JPG and PNG, with comparable or better image quality. Smaller images mean faster website loading times, improved SEO rankings, and reduced bandwidth usage.
