About PNG to ICO Converter
This tool converts a PNG (or JPG/WebP) image into a Windows .ico file, the format browsers and Windows use for favicons and app icons. You choose which sizes to pack in — 16, 24, 32, 48, 64, 128, and 256px are available — and it builds a single .ico that holds all of them, so software can pick whichever resolution it needs.
Everything happens in your browser using the Canvas API. Your image is never uploaded to a server. The tool draws your image into each square size, exports each layer as PNG, and assembles them into a standard multi-image .ico container. Because it embeds PNG data, the output works in modern browsers and Windows Vista and later; very old software that only reads BMP-based icons may not show the larger layers.
For the crispest result, start from a square PNG that is at least 256x256px. Non-square images are centered and padded with transparency rather than stretched, and any size larger than your source is scaled up (which can look soft), so the tool warns you when that happens.
Frequently asked questions
- What is an .ico file and why do I need one?
- An .ico is a Windows icon container that can hold several image sizes in one file. It is the classic format for a website favicon (favicon.ico) and for Windows program and shortcut icons. Bundling multiple sizes lets each program display the sharpest version for its context.
- Which sizes should I include for a favicon?
- 16, 32, and 48px cover browser tabs, bookmarks, and the Windows taskbar, and 256px is used by larger previews. That combination is a safe, widely recommended default, and it is preselected for you.
- Is my image uploaded anywhere?
- No. The conversion runs entirely in your browser with the Canvas API. Your file never leaves your device, so it is safe for private logos and unreleased artwork.
- My image is not square. What happens?
- Each icon layer is square, so a non-square image is scaled to fit and centered with transparent padding around it. Nothing is stretched or distorted. For best results, crop your image to a square before converting.
- Can I convert JPG or WebP too, not just PNG?
- Yes. Any image your browser can open — PNG, JPG, WebP, GIF, BMP — can be used as the source. PNG is recommended because it supports transparency, which icons usually need.
- Why does my 256px icon look blurry?
- If your source image is smaller than the size you selected, the tool has to scale it up, which softens detail. Start from a source at least as large as your biggest chosen size — ideally a 256x256px PNG — for sharp results.
