Why Compress PNG Images?

PNG files are great for quality but can be unnecessarily large. Compressing them reduces file size while keeping transparency intact.

• Faster page loads — smaller PNGs mean quicker website loading
• Keep transparency — unlike JPEG, PNG compression preserves alpha channels

❓ Frequently Asked Questions

Is PNG compression lossless?

Our PNG compression uses lossless optimization — your image quality remains identical while file size decreases. We optimize color palettes and remove unnecessary metadata.

How much can PNG files be compressed?

PNG compression typically reduces file size by 20-60% depending on the image content. Images with large uniform areas compress better than complex photographs.

What's the difference between PNG and JPEG compression?

PNG compression is lossless (perfect quality), while JPEG is lossy (smaller files). Use PNG for graphics, logos, and screenshots. Use JPEG compression for photos.
