Sample PNG File Download

PNG uses lossless compression, meaning the image you save is pixel-for-pixel identical to the one that gets decoded later — no generational quality loss the way JPEG has. It's also the standard choice whenever an image needs real alpha transparency, which JPEG doesn't support at all.

That losslessness comes at a cost: PNG files are typically larger than an equivalent JPEG, especially for photographic content with lots of color variation. It's the right tool for screenshots, logos, and icons with sharp edges or transparency — not necessarily for a photo library where file size matters more.

Use the download below to verify your app correctly handles PNG's alpha channel and lossless pixel data, rather than assuming JPEG handling covers it.
