Your files never leave your device. All processing happens in your browser.
Open the Img Stop Image to AVIF Converter, add your JPG, PNG or WebP images and set the quality. Click Convert to save them as AVIF, then download each file or all of them as a ZIP. Saving AVIF needs a browser that can encode it, such as a recent Chrome, Edge or Opera.
About the Image to AVIF Converter
The Img Stop Image to AVIF Converter turns JPG, PNG and WebP images into AVIF, a modern format that often gives much smaller files than JPG at similar quality. Smaller images make web pages load faster and save storage, and the quality slider lets you choose how small the file should be.
To be honest about one limit: the AVIF file is created by your browser, and not every browser can save AVIF yet. Recent Chrome, Edge and Opera can. In other browsers the tool saves a PNG instead and tells you so, so you always get a working file. Nothing is uploaded, and there is no sign-up or watermark.
