Why PNG is the default for cut-outs
PNG is lossless and supports a full alpha channel, so soft edges on hair and shadows survive intact; the W3C's Third Edition (2025) also adds animation and HDR [1]. JPEG can't store transparency at all — JFIF files have only greyscale or colour channels [2] — so a “transparent JPG” always comes back with a solid background.
When WebP or AVIF are better
When you need SVG instead
PNG is still made of pixels, so it blurs when enlarged. Logos and icons that must scale to any size belong in SVG, the W3C's vector format [5]. A PNG maker is ideal for photos and product shots; for a logo, keep the original vector file if you have one.
