PNG to ICO Converter

It turns PNG images into Windows Icon (ICO) files, the format used for website favicons and Windows application and shortcut icons. You choose one target size, from 16x16 up to 256x256 pixels, and each PNG is scaled to fit that square, centered, with its transparency kept. The image is stored inside the ICO as a compressed PNG, which current browsers and Windows versions read. Each ICO holds that one size, so if you need several sizes, convert again with a different setting. You can add multiple PNGs at once.

Save your logo or watermark as a square PNG with a transparent background, ideally at least 256x256 pixels. In the converter, choose the Target Icon Size first: 32x32 or 48x48 are good choices for a favicon, while 16x16 is the classic browser tab size. Then drop the PNG onto the upload area, or click to browse, and click Convert to ICO; the file downloads automatically. Put the ICO in your website's root folder as favicon.ico, or set it in your site builder's favicon settings, so your branding appears in tabs and bookmarks.

Modern browsers accept PNG favicons, but ICO is still the most widely recognized favicon format: many browsers and tools look for favicon.ico at the root of a site by default, and Windows uses ICO for application and shortcut icons. The ICO format can hold several sizes in one file, but this converter writes a single size per file, so pick the size closest to where the icon will appear. A 32x32 or 48x48 favicon usually displays crisply in tabs and bookmarks.

Use ICO when you set up the favicon for your portfolio or booking website, or when you need an icon for a Windows application, shortcut or folder, for example to mark a studio tool or an archive drive. For general web display, social media, client delivery or print, stay with JPEG or PNG. ICO is intended only for interface icons and system-level branding, so there is no reason to convert photographs to it.

Blurriness almost always comes from the source PNG or the size you chose. If the source is small, for example 32x32 pixels, converting it at 128 or 256 enlarges it and softens it, so start from a crisp PNG of at least 256x256. A non-square image is never stretched: it is scaled to fit inside the square and centered, with transparent margins on the short sides, so a wide logo can look small. Crop it to a square first for the largest result. Fine text and thin lines also become illegible at 16x16.

Many photo editing programs cannot export ICO without a plugin or a workaround. This converter does that one job in the browser: choose a size, add your PNGs, and each one is scaled, centered on a transparent square and packaged as an ICO file in seconds. There are no export menus to navigate and nothing to install. Your editing software is still the right place to design and refine the logo itself; this tool simply handles the final step of turning the finished PNG into an icon.

Yes, the conversion keeps the alpha channel transparency of your original PNG file. This is important for icons, as you typically want your logo or graphic to float seamlessly over various background colors in browser tabs or desktop environments. The image is drawn onto a transparent square, so non-square images also get transparent margins rather than a colored border. Check that your source PNG actually has a transparent background rather than a solid white or colored one, as the converter keeps exactly what is present in the original file.

The converter only accepts PNG files, and anything else dropped onto it is ignored. If a file does not appear in the list, check that it is genuinely a PNG and not a JPEG or other format renamed with a .png extension; re-saving it as PNG from your editing software fixes that. Large files are fine, since the image is scaled down to icon size anyway, although a huge image takes a moment longer. If a conversion seems stuck, refresh the page and try again in a current version of your browser.

Start with a square PNG of at least 256x256 pixels, the largest size the converter makes and the largest standard Windows icon size. A square source fills the icon completely, while a rectangular one is fitted inside the square with transparent margins. From that source, choose the size you need for each run: 16x16 for classic favicons, 32x32 or 48x48 for taskbar and desktop icons, and 64x64, 128x128 or 256x256 for large icons on high-resolution screens. A smaller source will look soft at the larger sizes.

Photographers work in a visual industry where presentation matters as much as the images. When potential clients visit your portfolio or open a gallery link on your site, the small icon in their browser tab is a subtle professional touchpoint, and a generic or missing favicon can make a website look unfinished. Turning your studio logo or signature into an ICO gives you a consistent brand mark in tabs and bookmarks, and lets you mark Windows shortcuts and folders for your own studio workflow.
