Resizing a transparent PNG with the wrong tool leaves dark fringes around edges. PhotoTools resamples with premultiplied alpha, so logos and icons keep clean edges at any size, and saves the result as an optimised PNG.

Frequently asked questions
Will the transparent background be kept?
Yes. Transparency is preserved exactly as in the original.
How do I make a favicon-sized PNG?
Choose a square size such as 512, 192 or 32 pixels. Use the Contain mode to avoid cropping a non-square logo.
Can I resize a PNG to a smaller file size?
Resizing reduces size a lot. For even smaller files, reduce the colors in the PNG compressor or convert to WebP.
Are my images uploaded to a server?
No. This tool runs entirely in your browser using WebAssembly. Your images never leave your device, and nothing is stored.
