Converting AVIF to PNG preserves pixels losslessly and keeps alpha transparency in a format every tool handles. For lossy AVIF sources, the existing artifacts transfer into the PNG's pixel data; for lossless AVIF, the conversion is exact.

Lossless in terms of what the AVIF currently contains. File size typically grows substantially; PNG can't match AVIF's compression efficiency, especially on photos. Alpha is preserved cleanly. HDR metadata doesn't round-trip through standard PNG.
PNG is supported everywhere: every browser, OS, and tool. Zero compatibility concerns.
AVIF is an image format built on the AV1 video codec, standardized in 2019. It supports HDR, wide color gamut, 12-bit depth, alpha, and animation. At matched perceived quality it's typically 50% the size of JPG and 20% smaller than WebP. Support is near-universal in modern browsers but spottier in image editors.
PNG is a lossless image format designed to replace GIF. It uses DEFLATE compression, supports an 8-bit alpha channel for full transparency, and preserves every pixel exactly. PNG excels at images with sharp edges, large flat-color regions, text, UI screenshots, and anything you'll re-edit.
Almost always, often by 3–10× for photographic content. AVIF is one of the most efficient image formats; PNG's lossless compression is far less aggressive.
Standard PNG is 8-bit sRGB. 16-bit PNG exists but doesn't support HDR metadata. HDR content in the AVIF is tonemapped to SDR during conversion.

Yes. The converter runs entirely in your browser using WebAssembly. Your images are never uploaded, never sent to a server, and never leave your device.
There's no hard limit, but because everything runs in your browser you're bounded by available memory. Very large images (over a few hundred megapixels) can hit browser memory limits. Process in smaller batches if you run into issues.
