PNG compression is best for screenshots, graphics, and transparent images. Resizing large PNG files often creates the biggest file size reduction.
Use PNG for sharp graphics, UI screenshots, logos, and images that require transparency.
How to compress png online
- Choose or drop a JPG, PNG, or WebP image.
- Adjust quality or set a maximum width and height.
- Preview the compressed result and file size reduction.
- Download the optimized image.
How it works
PNG is commonly lossless, so quality sliders may have less impact than they do for JPG or WebP. Dimensions and image complexity are major file size factors.
If the PNG is a photo and transparency is not needed, converting to JPG or WebP can make the file much smaller.
