What is a AVIF file?
AVIF is built on the AV1 video codec and delivers the strongest compression of any mainstream image format — files are often about half the size of an equivalent JPG and noticeably smaller than WebP at the same visual quality. It supports transparency, HDR, and wide color gamuts.
In short, AVIF is the newest web format with the best compression available. It is best for performance-critical websites where every kilobyte counts, and modern image pipelines that can serve fallbacks. Its main limitations are encoding is slower than other formats, and very old browsers or desktop tools may not open AVIF files.
Why convert AVIF to PNG?
PNG is a lossless format designed for the web. Every pixel is preserved exactly, and its alpha channel supports smooth, variable transparency — which is why logos, icons, and UI screenshots are almost always PNGs. The tradeoff is file size: photographs saved as PNG can be several times larger than an equivalent JPG.
Converting from AVIF to PNG makes sense when you need logos, icons, screenshots with text, diagrams, and any image that needs a transparent background. PNG is universally supported in every modern and legacy browser.
Both formats support transparency, and this converter preserves the alpha channel — transparent areas in your AVIF stay transparent in the PNG.
Because PNG is lossless, the conversion will not add any new compression artifacts — but it also cannot restore detail the original AVIF compression already discarded.
For animated AVIF files, this tool converts the first frame — the output PNG is a still image.
How to convert AVIF to PNG
Drag and drop one or more AVIF files into the box above (or click to browse). Then press Convert. Each file is decoded and re-encoded as PNG on your own device in a second or two, and you can download results individually or grab everything as a ZIP.
Unlike most online converters, FileLark never uploads your files to a server. The conversion runs entirely inside your browser using modern web technology, which means it works offline once the page has loaded, there are no file size queues or daily upload limits, and your images can never be stored, scanned, or leaked — they simply never leave your device.
