Compress PNG Files

The two most commonly used image formats in digital images are PNG and JPEG. PNG, which stands for Portable Network Graphics, was officially released in 1996. It offers lossless compression, high quality, and a wider range of colors, making it a favorite among designers due to its support for transparency. Additionally, its progressive display technology enhances the user experience when viewing large images.

However, due to its lossless nature and high color fidelity, large PNG images can be very large, making them difficult to store and browse online. This has led to the development of PNG compression algorithms and techniques.

Our PNG compression tool offers a simple and straightforward way to compress images, and it doesn’t require any additional software—just use it directly in your web browser.
