PNG to AVIF Converter
Convert PNG files to AVIF online for free. Use this PNG to AVIF converter for uploads, editing, websites, previews, and app compatibility.
Why convert PNG to AVIF?
Image formats differ in file size, transparency, editing support, and browser compatibility. PNG is often used for transparent graphics, screenshots, UI assets, and lossless images, while AVIF is useful for modern browsers, high compression, and image-heavy pages. Converting PNG to AVIF helps when a website, app, editor, or device expects the output format.
Before you convert
Check transparency, edge sharpness, colors, orientation, and whether the output opens in the app or upload form you plan to use. Keep the original PNG file until you have opened and reviewed the converted AVIF file.
Best uses for AVIF
AVIF output is best for modern browsers, high compression, and image-heavy pages. This converter is useful when you need a practical AVIF copy without installing desktop software.
Common upload errors this can fix
Use this converter when an upload form says the file type is not supported, when an app cannot preview the PNG file, or when a recipient needs a more familiar AVIF file. Always match the output to the format requested by the destination, especially for job portals, school submissions, marketplace listings, CMS uploads, and social platforms.
PNG vs AVIF
PNG is commonly used for transparent graphics, screenshots, UI assets, and lossless images. AVIF is commonly used for modern browsers, high compression, and image-heavy pages. The best choice depends on whether you need compatibility, editing support, smaller file size, stable layout, transparency, playback support, or a format that a specific upload form accepts.
Conversion checklist
After converting, open the AVIF file before deleting the original PNG. Check file size, readability, playback or preview behavior, and whether the converted file works in the exact app, website, or device where you plan to use it.

Will converting PNG to AVIF change quality?
