Build one proper .ico file from a PNG, with 16, 24, 32, 48, 64, 128 and 256 px icons packed inside. Drawn fresh at each size in your browser, nothing uploaded.

It builds one proper .ico file from your PNG, with seven icon sizes packed inside it: 16, 24, 32, 48, 64, 128 and 256 pixels. That full set is what Windows and browsers actually ask for. A browser tab wants the tiny sizes, a desktop shortcut wants the middle ones, and large displays reach for 128 and 256.
Many converters write a single size only, often just the largest. That leaves the small sizes to be shrunk on the fly by the system, which is where blurry favicons come from. Here your picture is drawn fresh at each of the seven sizes and all of them travel inside the one file.
The ICO format is a container, not a single picture. It was designed so one file can carry a whole family of the same icon at different sizes, and the system picks the closest match for each spot. The 256 pixel version is stored as PNG data inside the file, which keeps it compact and sharp.
Transparency carries through as well. ICO stores full color with an alpha channel, so a logo with a clear background stays clear at every size. That is one reason a PNG is the right starting point: it keeps the transparency and the clean edges that a JPG would flatten and fuzz.
Square sources work best. If your PNG is not square, the tool fits the whole picture inside the square frame rather than chopping the sides off, so nothing important gets cut. Wide logos will sit smaller in the frame, which is worth knowing before you judge the result.
Start from the largest, cleanest PNG you have, because every small size is drawn down from it. A crisp 512 or 1024 pixel source gives the drawing more real detail to work with at 16 and 32 pixels. A small or already blurry source cannot be rescued, and scaling it up first adds nothing.
Simple marks win at icon sizes. A single letter, a bold shape or a short monogram stays readable in a browser tab. A detailed photo does not, no matter which converter you use. If your logo has a detailed version and a simple version, feed the simple one to this tool.
For the other sizes a website needs around the favicon, such as touch icons and social images, the image converter and the image resizer cover the PNG side of the set. More format pairs live in the image converters category.
A site owner finishes a logo and needs favicon.ico before launch. A small software maker wants one icon file that looks right from the taskbar to a 4K desktop. A designer hands over a PNG mark and the developer asks for ICO, because that is the format Windows expects. All three jobs need the same thing: every size, in one file, drawn cleanly.
The drawing and packing happen in your browser. Your PNG is never uploaded to a server, never stored and never seen by anyone at ToolPeko. Unreleased logos and app icons stay on your device, and closing the tab leaves nothing behind.
The set Windows and browsers ask for is 16, 24, 32, 48, 64, 128 and 256 pixels. Small sizes serve tabs and taskbars, large sizes serve desktops and high resolution screens. This tool packs all seven into one file.
At 16 pixels there is room for only the boldest shapes. Detailed logos and photos blur because the detail has nowhere to go. Use a simplified mark for icons, and start from a large clean PNG so the small sizes are drawn from real detail.
A square PNG, at least 256 by 256 pixels, with a simple bold design. Bigger is better, up to about 1024 pixels. Transparency is fine and carries into the icon. A non-square picture is fitted into the square without cropping.
Modern browsers accept PNG favicons too, and many sites use both. ICO is still the classic favicon.ico format and the one Windows needs for app icons, shortcuts and pinned programs. One ICO also carries many sizes in a single file.
Yes. ICO supports an alpha channel, so clear areas in your PNG stay clear at every packed size. Nothing is flattened onto white or any other color.
Not directly here, and the detour costs quality. JPG flattens transparency and softens edges, which shows badly at 16 pixels. Convert the JPG to PNG first if you must, but a true PNG original always makes the sharper icon.
