PNG to ICO
Convert PNG or JPG images to Windows ICO favicon files. Generates a multi-size icon (16, 32, 48, 64, 128, 256 px).
How PNG to ICO works
Use a square image for best results (e.g. 512×512 or larger).
The image is rendered on canvas at 16, 32, 48, 64, 128 and 256 pixels — all six sizes are packed into one .ico file.
Use as favicon.ico for websites or as an application icon on Windows.
Frequently asked
What sizes does the ICO contain?+
16, 32, 48, 64, 128, and 256 pixels — the standard set for websites and Windows apps.
Can I use a non-square image?+
Yes, but the image will be letterboxed to fit each square size. Square inputs look best.
Is the file uploaded to any server?+
No. Icon generation runs entirely in your browser.
How do I install this as a favicon?+
Save the file as favicon.ico in your website root, or add <link rel="icon" href="/favicon.ico"> to your HTML head.
Pro drops a folder of images and returns one ZIP of .ico files — same engine, same privacy, still zero uploads.
