Convert PNG to AVIF Online for Free

AVIF offers superior compression to PNG, producing much smaller files with excellent quality. Converting to AVIF is ideal for modern websites that want fast load times with transparency support.

Yes, this converter is completely free to use with no limits. There is no sign-up, no subscription, and no watermarks on your converted images.

Your files are processed securely and never stored on our servers. The conversion happens in your browser when possible, and any server-side processing is done in memory and discarded immediately.

You can upload files up to 50 MB. Most image files are well within this limit. If your file is too large, consider resizing it before converting.

Portable Network Graphics is a lossless raster image format that supports transparency. It is widely used for web graphics, screenshots, and digital art where quality preservation is important. PNG files tend to be larger than JPEGs but do not lose quality through repeated saves. In contrast, AVIF is a next-generation image format based on the AV1 video codec, offering excellent compression efficiency. It supports HDR, wide color gamut, and transparency while producing smaller files than JPEG and WebP. Browser support is growing rapidly across Chrome, Firefox, and Safari.

Yes! You can upload up to 20 files at a time. The converter processes them one by one in sequence and displays each result with its own download button as soon as it is ready.

Since AVIF uses lossy compression, there may be a slight reduction in quality. You can control this with the quality slider — higher values preserve more detail but produce larger files.
