What is AVIF?
AVIF is a modern image format that can reduce file size while maintaining good visual quality. It supports transparency and efficient compression, making it a strong choice for photographs, product imagery, and web assets that need to stay sharp without wasting bandwidth.
Why use this converter?
Use this tool when you need smaller, web-ready images without sending files to a server. It converts images locally in your browser and lets you adjust quality, encoder speed, lossless mode, and output scale before downloading. When you convert multiple images, it also prepares a ZIP for easy batch saving.
How it works
- Upload one or more image files.
- Choose AVIF quality, speed, lossless mode, and output scale.
- Convert the files in a browser worker.
- Preview each result, download individual AVIF files, or download the ZIP.
Tips for better results
- Use a quality value around 70-80 for photographs and screenshots as a practical starting point.
- Lower quality when file size matters more than fine detail.
- Lower speed values can produce smaller files but take longer for large images or batches.
- Use lossless mode for diagrams, UI assets, or images that need exact color preservation.
- Keep scale at 100% for format-only conversion, or reduce it when the image will be displayed smaller on the page.
- Compare original and output file sizes because some very small or already compressed images may not shrink after AVIF encoding.
