About these image formats
What is PNG?
PNG (Portable Network Graphics) is a lossless raster format that supports transparency. It is ideal for logos, icons, screenshots, and graphics that need sharp edges.
How to open: PNG files open natively in all browsers and operating systems. They are the standard format for web graphics with transparent backgrounds.
Best for: Use PNG when you need transparency, lossless quality, or crisp text and line art.
What is WebP?
WebP is a modern image format developed by Google. It offers 25–35% smaller file sizes than JPG or PNG at similar quality, with support for both lossy and lossless compression.
How to open: WebP is supported in Chrome, Firefox, Safari 14+, and Edge. Older software may require conversion to JPG or PNG.
Best for: Use WebP for faster website loading and reduced bandwidth. Convert to JPG when you need maximum compatibility.
