PNG Compression FAQ
Everything you need to know about compressing PNG images.
PNG compression reduces file sizes by optimizing the way image data is stored. Our tool uses advanced algorithms like UPNG.js to compress PNG files while preserving transparency and image quality. You can choose between lossless compression (no quality loss) or lossy compression (smaller file sizes with minimal quality reduction).
PNG compression results vary based on the original image content and complexity. Typically, you can achieve 40-80% file size reduction for graphics and logos, and 20-50% for screenshots and photos. Our adjustable quality settings (10-100%) let you control the balance between file size and visual quality.
Yes! Our PNG compressor maintains full alpha channel transparency during compression. Whether you're compressing logos, icons, or graphics with transparent backgrounds, the transparency will be preserved perfectly in the compressed output.
