Sample PNG images

PNG is a common image storage format. Unlike JPEG, it compresses without loss of image quality and it is possible to create images with a transparent background. Below are the images in this format available for download

🧠 How PNG Works

PNG compresses images losslessly — every pixel is preserved exactly. The format supports transparency (alpha channel) and up to 48-bit color. Compression works in two stages: row filtering + DEFLATE algorithm (same as ZIP). Here is how it works:

🖼 RGBA original image 🔍 Filtering prediction of neighboring pixels 📦 DEFLATE lossless compression (same as ZIP) 🧱 Chunks IHDR, IDAT, IEND data blocks + CRC 💾 .png final file
