PNG is lossless — every pixel is preserved exactly. JPG uses lossy compression that reduces quality. Choose PNG when you need perfect quality for editing, design work, or archival. PNG also supports transparency, which JPG cannot.
Yes! WhiskFile includes a built-in WebAssembly decoder (heic2any/libheif) that works on all modern browsers. Most HEIC converters rely on native browser support which fails on Windows Chrome/Firefox.
Usually yes. HEIC uses efficient HEVC compression while PNG uses lossless compression. A 3 MB HEIC photo might become 10-15 MB as PNG. This is the trade-off for zero quality loss.
No. Everything happens in your browser using WebAssembly. Your photos never leave your device, making it completely private.
Yes, by default transparent areas in the HEIC are preserved in the PNG output. You can optionally toggle on 'Fill Background' to replace transparent areas with a solid color.
