Why compress PNG images?

Compressing PNG images is useful when you want smaller files for websites, uploads, documents and storage. Large PNG files can slow down pages, increase upload times and make documents or media libraries heavier than necessary.

For websites, compressed PNG files can help improve loading speed while keeping graphics clean and readable. For documents and presentations, smaller PNG files are easier to manage. For online forms, compression can help keep images within upload limits.

PNG images and transparency

PNG

PNG is a popular image format for graphics, screenshots, logos, icons and images with transparent backgrounds. It is useful when you need sharp edges, readable text, clean interface screenshots or transparency.

Transparent PNG

Transparent PNG files are often used for logos, product graphics, stickers, overlays and design assets. Compressing a transparent PNG can help reduce file size while keeping the transparent background when supported by the compression process.

PNG compression behaves differently from JPG compression because PNG is often used for crisp graphics and transparency. The final file size reduction may vary depending on the image.
