Optimize PNG screenshots

PNG is commonly used for screenshots, documentation captures, UI exports, and flat graphics. This PNG image optimizer reduces file size while keeping the output in PNG format.

Compress PNG with transparent background

PNG transparency is preserved during compression, so transparent icons, logos, product graphics, and UI assets keep their alpha backgrounds after download.

Reduce PNG file size for websites

PNG files can be heavy on landing pages, ecommerce pages, and documentation sites. Use compression before uploading PNG screenshots, transparent assets, and web graphics to a CMS or builder.

FAQ

Does PNG compression keep transparency?

Yes. PNG transparency is preserved. Higher Quality values are best for complex semi-transparent artwork and gradients.

What does PNG quality mean?

For PNG, quality controls how aggressively colors may be reduced. Higher quality keeps more color detail; lower quality can make files smaller.

Why are PNG files large?

PNG preserves detail and transparency, so large screenshots, transparent graphics, and photo-like PNG files can become heavy.

Should I compress PNG or convert PNG to WebP?

Compress PNG when you need PNG output. Convert PNG to WebP when smaller modern website delivery matters more than PNG compatibility.
