What is PNG Compressor?

A PNG compressor is a tool designed to reduce the file size of PNG (Portable Network Graphics) images while preserving their quality and transparency. PNG is a lossless format, which means it retains all image details and is ideal for graphics, icons, logos, and images with text or sharp edges. However, because it preserves so much data, PNG files can be larger than other formats like JPEG, making them less efficient for web use or sharing.

A PNG compressor works by optimizing how image data is stored without altering how the image looks. It removes unnecessary metadata, applies advanced compression algorithms, and restructures the image internally to make the file smaller. Unlike lossy compression formats, these tools focus on smart optimization rather than removing visual detail, ensuring that your image stays clean and crisp.

Using a PNG compressor can significantly improve website performance, reduce upload times, and save storage space, especially when working with lots of high-resolution graphics.
