PNG vs JPG Compression Comparison

PNG utilizes lossless compression to maintain pixel-perfect quality and transparency, while JPG employs lossy compression to significantly reduce file sizes. Both formats are processed locally in your browser using libvips (WebAssembly) to ensure your data remains private.

Key Features

  • Lossless PNG compression preserves exact pixel data and alpha transparency.
  • Lossy JPG compression reduces file size by discarding non-essential visual data.
  • Client-side processing via libvips (WebAssembly) ensures no files are uploaded to a server.
  • Support for batch conversion to optimize entire image libraries locally.
  • Direct browser-based format conversion without external dependencies.
