Definition
A transparent PNG stores per-pixel alpha so the background remains transparent on any design surface.
Alpha channel basics
Each pixel has color plus opacity. Background pixels become alpha 0, foreground pixels stay opaque.
Edge quality
Good exports preserve semi-transparent edge pixels for smooth transitions.
When to use PNG
Use PNG for graphics with transparency requirements in marketplaces, design files, and ads.
FAQ
Why not JPG?
JPG has no alpha channel, so transparency is lost.
Can I use WebP?
Yes. WebP can support transparency with smaller file sizes in many workflows.
