Optimize PNG screenshots

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

Compress PNG with transparent background

PNG transparency is preserved during compression. This makes the tool useful for icons, transparent product graphics, logos, and UI assets with alpha backgrounds.

Reduce PNG file size for websites

PNG files can be heavy on websites when they include screenshots, flat graphics, or transparent assets. Compression helps reduce bytes before upload to a CMS or ecommerce page.

PNG optimizer vs PNG to WebP converter

Use this PNG optimizer when you need PNG output. If the smallest modern website file matters more than PNG compatibility, convert PNG to WebP instead.

FAQ

Does PNG compression keep transparency?

Yes. PNG transparency is preserved.

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 photo-like images, large screenshots, and complex graphics can become large.

Should I compress PNG or convert PNG to WebP?

Compress PNG when you must keep PNG output or transparency workflows. Convert to WebP when modern web delivery and smaller files are the priority.
