COMPRESS PNG

When we talk about digital files, compression means reducing a file’s size by removing some of the data it contains. In many cases, this means stripping out empty or unnecessary bits of information so that the file becomes smaller but still looks identical. This is known as lossless compression.

However, when parts of the file that actually affect its quality are removed, that’s called lossy compression. In this case, the file gets smaller, but there might be a slight reduction in visual or audio quality depending on the file type.

The tool provided on this page performs lossy compression for PNG images by reducing the number of colors in the file’s color palette.

Why Compress PNG Files?

PNG is a popular image format used for graphics, icons, and logos because it supports transparency. This allows you to overlay a PNG on top of another image while keeping parts of the background visible, something you can’t do with many other formats like JPG.

PNG files can use either 24-bit or 8-bit color depth. A 24-bit PNG supports millions of colors but takes up more space, while an 8-bit PNG supports fewer colors but has a much smaller file size.

If your website logo or simple design is saved as a 24-bit PNG, it’s likely using more storage and bandwidth than necessary. By converting it to an 8-bit version, you can significantly reduce file size without noticeably affecting how it looks.

This means faster loading times for your website and less storage space used overall especially if your site uses many PNG images. Even small optimisations like this can greatly improve page speed and user experience.
