Specification https://www.w3.org/TR/PNG/ https://developers.google.com/speed/webp/docs/riff_container
Description PNG (Portable Network Graphics) is a lossless raster image format designed to improve upon the limitations of the older GIF format. It supports millions of colors, full alpha transparency, and optional interlacing. Because it uses lossless DEFLATE compression, PNG preserves every pixel exactly as stored, making it ideal for graphics that need sharp edges, text clarity, and no degradation over multiple saves. WebP is a modern image format developed by Google that provides superior compression compared to traditional formats like JPEG and PNG. It supports both lossy and lossless compression, alpha transparency, and animation in a single format. This versatility makes it particularly valuable for the web, where reducing file sizes without sacrificing visual quality directly improves page load speeds and user experience.
Typical usage
  • Web graphics where image clarity is critical
  • Icons and UI elements that require transparent backgrounds
  • Screenshots of applications or websites
  • Digital charts, diagrams, and infographics
  • Web graphics and photos where smaller file sizes improve page performance
  • Images that require transparency with minimal size impact
  • Replacing both JPEG and PNG assets with a single format for efficiency
  • Animated images as a more efficient alternative to GIF
Typical use cases
  • Preserving pixel-perfect quality for logos and branding materials
  • Creating assets for responsive web design where crisp scaling is important
  • Maintaining text sharpness in interface screenshots
  • Storing intermediate design work before final export to other formats
  • Optimizing e-commerce product images to load quickly without quality loss
  • Serving responsive images for high-DPI (Retina) displays while keeping bandwidth low
  • Replacing animated GIFs with smaller, smoother WebP animations
  • Reducing storage and CDN bandwidth costs for large image libraries
Widely supported by
  • All modern browsers (Chrome, Firefox, Safari, Edge)
  • Popular design software such as Adobe Photoshop, GIMP, and Affinity Photo
  • Image processing libraries like Sharp, libpng, and ImageMagick
  • All major browsers (Chrome, Firefox, Edge, Safari 14+)
  • Design tools like Photoshop (with plugin), GIMP, and Affinity Photo
  • Image processing libraries including libwebp, Sharp, and ImageMagick

Animation support No — PNG itself does not support animation, but the APNG extension (Animated PNG) enables frame-by-frame animations while retaining lossless quality. Yes — WebP supports multi-frame animation with both lossy and lossless compression, enabling high-quality animated images at significantly smaller file sizes than GIF.

Advantages
  • Lossless compression retains exact image quality regardless of edits or re-saves.
  • Supports a full alpha channel for smooth transparency and blending effects.
  • Can store high bit depth images (up to 16 bits per channel), making it suitable for professional work.
  • Universally supported across browsers, operating systems, and image viewers.
  • Significantly smaller file sizes than JPEG or PNG at equivalent visual quality.
  • Supports both lossy and lossless compression modes in one format.
  • Full alpha channel support for transparency in both compression modes.
  • Animation support makes it a superior alternative to GIF for quality and file size.
  • Broad browser and tool support has grown, making it viable for production web use.
Disadvantages
  • File sizes can be significantly larger than JPEG for photographic images due to lossless compression.
  • Does not inherently support animation without APNG extension.
  • Large high-resolution PNGs can be memory-intensive to decode in browsers or apps.
  • Older browsers and some legacy devices lack native WebP support, requiring fallback formats.
  • Encoding complexity can be higher, making compression slower for very large images.
  • Not ideal for archival purposes since some software ecosystems still favor traditional formats.
Max size note While technically supporting very large dimensions, decoding extremely large PNGs can consume high amounts of RAM, potentially leading to performance issues in browsers. While WebP reduces average image sizes significantly, excessively large images can still lead to high memory usage during decoding, especially with animations.
