MEDIA Format
PNG (Portable Network Graphics) is an image format that uses lossless compression, meaning no image data is discarded during compression. It supports full transparency (alpha channel), making it the standard choice for logos, icons, screenshots and images that require a transparent background.
PNG vs JPEG
JPEG uses lossy compression and does not support transparency. PNG uses lossless compression and supports an alpha (transparency) channel. For photographs, JPEG produces much smaller files because lossless compression of photographic detail is inefficient. For graphics with flat colours, sharp edges or transparency, PNG is more appropriate.
A PNG photograph is typically 3–5x larger than the equivalent JPEG. A PNG logo with transparency is usually the only sensible format choice for that use case.
PNG and WebP
WebP supports both lossy and lossless modes, and also supports transparency. A WebP lossless version of a PNG is typically 26% smaller. For sites with many PNG files, converting to WebP lossless reduces storage and bandwidth without visible quality change.
Mediapapa Pro converts PNG files to WebP as part of its bulk compression pass. Transparent PNGs are converted to WebP with transparency preserved.
Frequently asked questions
When should I use PNG instead of WebP?
If broad browser compatibility is critical and you cannot serve WebP to unsupported browsers. For most modern sites, WebP is the better choice. Mediapapa’s conversion preserves transparency.
Does PNG support animation?
APNG (Animated PNG) supports animation, but standard PNG does not. Animated images are more commonly handled with GIF or WebP. APNG is not widely used in WordPress contexts.
