Convert PNG to ICO
Turn your logo or icon PNG into a ready-to-ship favicon.ico. The converter fits the whole image into the three standard favicon sizes instantly on your device; nothing is uploaded and no account is needed.
Your images never leave this browser. No upload, no server, no AI model call: just instant local processing.
Selected files: 0 · PNG, JPEG and WebP · up to 8 MB per file and 12 million pixels · 40 MB per batch. Animated files export as one clean still.
Your export is a fresh, clean file: no saved prompts, EXIF or Content Credentials ride along. Keep the original when you need its creation records.
How to convert a PNG to ICO
Pick a PNG up to 8 MB, ideally a square logo or icon with a transparent background, or try the example. Select Run tool. The converter scales your image into three square canvases of 16 × 16, 32 × 32 and 48 × 48 pixels without cropping; a wide or tall image is centered with transparent space around it. Each size is stored as a PNG-compressed entry inside one ICO file.
Preview the 48-pixel icon, then download favicon.ico and drop it at the root of your website or reference it from a link tag in your page head. Check the 16-pixel version in a browser tab: bold shapes shine at that size, while fine lines and small text blur, so simplify the artwork if you need to. Transparent corners stay transparent. The ICO is a clean export with none of your original PNG's saved metadata.
- Pick a PNG from your device, or select Try an example to load a test PNG.
- Select Run tool. The page fits the image into 16, 32 and 48 pixel squares and builds one ICO file on your device.
- Review the preview and output bytes, then download favicon.ico.
Your questions, answered
How do I convert a PNG to ICO without losing quality?
Start from a square PNG of at least 256 × 256 pixels with a transparent background. This converter stores each icon size as a lossless PNG entry inside the ICO, so the only change is the scaling down to 16, 32 and 48 pixels. Bold shapes keep their edges at those sizes; thin lines and small text are what blur.
How do I make an icon file (.ico) from a PNG?
Pick the PNG on this page and select Run tool. Your browser builds one favicon.ico holding 16, 32 and 48 pixel icons, ready to download. It works for website favicons and Windows shortcut icons, with no upload and no account.
How do I convert a PNG to ICO?
Pick the PNG on this page and select Run tool. Your browser builds one ICO file containing 16, 32 and 48 pixel versions of the image, and you download it as favicon.ico. No settings, no upload, no account.
Does the ICO keep my PNG's transparency?
Yes. Each icon size is drawn on a transparent square and stored as a PNG entry, so transparent areas stay transparent. The space added around a non-square image is transparent too.
