PNG to ICO
PNG to ICO for favicons and shortcuts
Load a PNG and this page stacks the icon sizes you pick into a single Windows .ico file, entirely in your browser. No library, no server, no upload. Honest limits: ICO entries are square so non-square images are center-cropped, sizes larger than the source are skipped instead of upscaled, and the entries use PNG-compressed images that Windows Vista and later read - old XP-era icon tools may not.
- ICO files hold several square sizes at once, so Windows can pick the right one for a taskbar, a desktop shortcut or a browser tab.
- Entries are square: a non-square PNG is center-cropped to its shorter side before the icon is drawn.
- Sizes larger than the source are skipped, never upscaled - an upscaled icon only blurs the pixels you already have.
- The entry that matches the source size embeds your original PNG bytes unchanged - that one is lossless.
- Resized entries are re-encoded by this browser as PNG, which keeps alpha transparency intact but is not bit-identical to your source.
- PNG-compressed entries need Windows Vista or newer; Windows XP icon properties may show a blank image.
- An animated PNG (APNG) keeps only its first frame - the ICO format carries no animation.
- At 16 x 16 fine detail turns to mush - design with large shapes and strong contrast, then check the smallest entry.
- The usual favicon set is 16, 32 and 48; 256 suits high-resolution displays, and extra entries only bloat the file.
- Palette, grayscale and interlaced sources are valid but get re-encoded to 32-bit PNG on resize, which can change the file size.
- The conversion runs on this page: your file is read, repacked and downloaded, never uploaded.
