Why compress PNG files
PNG is ideal for graphics, screenshots, and images with transparency. However, PNGs can be surprisingly large.
Compression cuts storage and bandwidth costs without converting to another format or removing the alpha channel.
Tips for better PNG compression
Choose the Max preset for the strongest size reduction. For screenshots and flat graphics the savings are often 40–70%.
Photographs stored as PNG may benefit more from converting to JPG first, then compressing.
Frequently Asked Questions
Will PNG transparency be preserved?
Yes. The compressor maintains the alpha channel so transparent areas remain intact.
How much smaller will my PNG get?
Results depend on image content and preset choice. Graphics with solid colors typically compress more than complex photos.
Do I need to install anything?
No installation required. The tool runs directly in your web browser on any operating system.
