PNG (Portable Network Graphics) is a widely used image format known for two things: it supports transparent backgrounds, and it keeps every pixel sharp without quality loss. That combination makes it the natural choice for logos, icons, line graphics and screenshots where clean edges and see-through areas matter.
Picture a sticker versus a printed photo. A sticker has a cut-out shape that sits on any surface, while a photo is always a solid rectangle. A PNG is the sticker: its transparent areas let a logo float cleanly over any colour or image behind it. A JPEG is the photo, better for rich, full-frame images where small detail loss is invisible anyway.
There is a simple test for which one to reach for. Does the image have flat colour, sharp text, or a transparent edge? Use PNG. Is it a photograph full of gradients and fine variation? Use JPEG. A screenshot of an app with crisp UI text stays readable as a PNG but turns muddy as a JPEG, because JPEG compression smears the hard edges it is bad at. Get this choice wrong and a logo can end up with an ugly grey halo where the transparency should have been. The trade-off is file size. Because PNG is lossless, it stores more data and the files are heavier, so it is the wrong choice for large photographs on a fast website. For crisp brand elements, though, it is hard to beat, which is why it shows up so often in iconography and responsive logo work. Many teams now reach for WebP or SVG too, but PNG remains the safe, universally supported fallback.
At TopDevs we pick the right format per asset, PNG for transparent logos and icons, lighter formats for photos, so client sites stay both crisp and fast.
