Welcome to the most advanced browser-based PNG to AVIF converter. AVIF (AV1 Image File Format) is the modern successor to JPEG and PNG, offering superior compression without sacrificing visual fidelity. By converting your PNG images to AVIF, you can reduce file sizes by up to 80% while preserving transparency and intricate details.
Our tool runs entirely on your device using advanced web technologies. This means your photos are never uploaded to a server, ensuring 100% privacy. Whether you are a web developer optimizing site performance or a photographer looking to save storage space, this tool provides granular control over quality, chroma subsampling, and encoding speed.
The interface is designed for efficiency. The dark mode studio environment allows you to focus on the visual output, while the "Before & After" slider guarantees you never compromise on quality. With support for batch processing, you can optimize entire galleries in seconds.
Getting started is effortless. Simply drag your PNG files into the neon-edged drop zone above, or tap the area to open your file browser. Once uploaded, each image appears as a "Studio Card" displaying its original resolution and file size.
The conversion begins automatically using the default "Balanced" settings. You will see a glowing progress line at the bottom of each card. Once complete, the new file size and a download button will appear.
To fine-tune a specific image, click on its card to open the Comparison Editor. Here, you can adjust the quality slider and instantly see the visual difference between the original PNG and the compressed AVIF. Use the drag handle to sweep across the image. When satisfied, click "Apply". You can download images individually to ensure the highest integrity for each file.
AVIF is a next-generation image format that offers significantly better compression than PNG. It supports transparency (alpha channels) just like PNG but produces files that are often 50-80% smaller. This leads to faster website loading times, better SEO scores, and reduced bandwidth usage without a noticeable drop in image quality.
Absolutely. Unlike many other online converters, Randomly.online processes your images locally within your web browser. Your files are never uploaded to our servers or the cloud. The conversion happens on your device's processor, ensuring that your personal photos or sensitive documents remain completely secure and private.
Yes, our converter fully supports transparency preservation. Since PNGs are often used for logos and graphics with transparent backgrounds, we ensure the alpha channel is retained during the conversion to AVIF. You can verify this using the checkerboard background in the preview cards or the editor mode.
