Why Compress PNG Images?

PNG (Portable Network Graphics) is a popular format for images that require transparency, such as logos, icons, and graphics. While PNG offers excellent quality, files can be large, making them slow to load on websites and difficult to share.

Compressing PNG images is essential for:

  • Web Performance: Reduce page load times and improve Core Web Vitals scores
  • Transparency Preservation: Maintain alpha channels while reducing file size
  • Logo Optimization: Smaller logos load faster without quality loss
  • Icon Libraries: Compress icon sets for faster app performance

PNG Compression FAQ

Does PNG compression preserve transparency?

Yes! Our PNG compressor fully preserves alpha channel transparency. Your transparent backgrounds and semi-transparent elements will remain intact after compression.

How much smaller will my PNG file be?

Compression results vary based on the original image, but typically you can expect 40-80% file size reduction. Complex images with many colors compress more than simple graphics.

Should I convert PNG to JPG?

Only if you don't need transparency. Converting PNG to JPG removes transparency but can offer better compression for photographic images. Keep PNG for logos, icons, and graphics with transparency.

Can I compress multiple PNG images at once?

Yes! Use our Batch Image Compressor to compress up to 100 PNG images simultaneously. Perfect for compressing logo sets, icon libraries, or entire image folders.
