Frequently Asked Questions
PNG compression works by reducing the color palette and optimizing the internal data structure. Our algorithm analyzes each image and applies the best combination of lossless and lossy techniques to achieve maximum size reduction while preserving visual quality and transparency.
Yes. Our PNG compressor fully preserves the alpha channel (transparency). Your logos, icons, and graphics will retain their transparent backgrounds after compression.
Lossless compression reduces file size without any quality loss - the image is pixel-perfect identical. Lossy compression reduces the color palette which achieves much smaller file sizes but may have slight color variations. For most web use, lossy is recommended.
