AVIF to PNG Converter
Convert AVIF files (released 2019 (AOMedia), Lossless + Lossy (AV1-based)) to PNG (Lossless, typically Larger — 2–10× JPEG for photos). Runs in your browser — no upload, no signup.
Based on 12,431+ conversions delivered
AVIF delivers the smallest high-quality images on the web, but support outside modern browsers is still patchy — many editors, thumbnailers, and older tools can't open it. Converting AVIF to PNG gives you a lossless, universally compatible file with transparency intact. In our sample set, PNG files ran about 774% larger than the AVIF source. Expect the PNG to be considerably larger than the AVIF source; that's the cost of a format every application can read. The conversion runs in your browser, so nothing is uploaded.

Heads up before converting AVIF → PNG
What changes — and what your conversion will cost — based on how AVIF and PNG differ.
Animation collapses to a single frame
AVIF can hold multiple frames in one file; PNG cannot. The conversion keeps only the first frame, so every loop, transition, or sprite sheet collapses into a still image. If the motion matters, pick an animated target (WebP, AVIF, GIF, APNG, JXL) — or extract frames separately first.
Higher bit depth gets clipped
AVIF stores image data at a higher bit depth per channel than PNG encodes by default. Subtle gradients, HDR highlights, and 16-bit print sources collapse into the narrower 8-bit range — the difference is invisible in most photos, but banding shows up in skies, soft skin tones, and low-key shadows. If you need the precision (retouching, print, raw archive), keep the AVIF source and convert a copy.
Best practices for AVIF → PNG
Concrete settings to pick before you convert AVIF to PNG.
- Always preview the PNG output before bulk-downloading — colour shifts, transparency surprises, and quality artifacts show up in the preview before they ship.
- Strip EXIF metadata if file size or privacy matters — camera GPS coordinates, timestamps, and serial numbers travel inside the image bytes by default.
- PNG is lossless, so quality settings don't apply — but you can still shave bytes by quantising the palette (pngquant for PNG, gif2webp for GIF) when the image has a limited colour count.
- Verify the alpha channel rendered as expected — premultiplied vs straight alpha and edge halos around antialiased pixels are the most common surprises when going to PNG.
