PNG/JPEG → AVIF or WebP Image Compressor

AVIF (AV1 Image File Format) is a modern image format that offers superior compression compared to JPEG, PNG, and WebP. AVIF images are typically 30–50% smaller than JPEG files while maintaining the same visual quality. This means faster website loading times, reduced bandwidth usage, and better user experience. AVIF also supports transparency, HDR imaging, and wide color gamuts for professional-quality results.

Yes, our converter allows you to adjust quality settings and resize images during the conversion process. You can balance file size and image quality based on your needs. Higher quality settings preserve more detail but result in larger files, while lower settings maximize compression for faster web loading.

AVIF is supported by all major modern browsers including Chrome, Firefox, Edge, and Opera. Safari has also added AVIF support in recent versions. For maximum compatibility, consider using AVIF with WebP or JPEG fallbacks in your web development. Browser support for AVIF continues to grow rapidly as it becomes the new standard for web images.

Promptus builds privacy-first tools that keep your data on your device, so you maintain full control over your images throughout the conversion process.

AVIF files are typically 60–80% smaller than equivalent PNG files, depending on the image content and quality settings. For photographs and complex images, the savings can be even more dramatic. This significant size reduction translates to faster website loading, reduced bandwidth costs, and improved user experience, especially on mobile devices and slower internet connections.
