A favicon (short for "favorite icon") is a small icon associated with a website. It appears in browser tabs, bookmark lists, browser history, and search results. Favicons help users quickly identify your website among multiple open tabs and bookmarks. Most modern browsers support multiple favicon sizes for different contexts — from tiny 16×16 pixel tab icons to large 512×512 pixel icons used by Progressive Web Apps (PWAs) for home screen shortcuts and splash screens.

What sizes do I need for a favicon?

For comprehensive cross-browser and cross-device support, you need: 16×16 (standard tab icon), 32×32 (HiDPI tab icon), 48×48 (Windows site icon), 180×180 (Apple Touch Icon), 192×192 (Android Chrome icon), and 512×512 (PWA install icon). PNGtoFavicon generates all of these automatically from a single PNG upload, plus a multi-size favicon.ico file.

How do I add a favicon to my website?

After downloading your favicon package from PNGtoFavicon, extract the ZIP file to your website's root directory and add the provided HTML link tags inside your section. PNGtoFavicon generates the exact HTML code snippet you need, ready to copy and paste.

Is my image uploaded to a server?

No — your image never leaves your browser. PNGtoFavicon processes everything 100% client-side using JavaScript and the HTML5 Canvas API. No data is sent to any server, making this the most private favicon generator available.

What file formats are supported for input?

PNGtoFavicon accepts PNG (recommended, supports transparency), JPG/JPEG, SVG (vector format), WEBP (modern format), and GIF. For best results, use a square PNG image of at least 512×512 pixels with a transparent background.

What is the difference between .ico and .png favicons?

The .ico format is a legacy container that can hold multiple icon sizes in a single file, required for compatibility with older browsers. Modern browsers prefer individual .png files specified with link tags, offering better quality and smaller file sizes. PNGtoFavicon generates both formats.

What is site.webmanifest and do I need it?

The site.webmanifest is a JSON file that tells browsers about your web application — including its name, theme color, and icon references. It's essential for Progressive Web App (PWA) functionality and improves compatibility with Android Chrome and other modern browsers.

How Our PNG to Favicon Converter Works

Discover the advanced browser-based technology we use to generate your favicons securely

Local File Reading

Once you drag & drop or browse your PNG image, the browser utilizes the HTML5 FileReader API to read your file locally, converting it to a secure in-memory data stream without uploading a single byte to external servers.

Offscreen Downscaling

To generate all necessary resolutions, the tool spins up hidden, offscreen HTML5 Canvas elements. It applies bilinear interpolation filters to scale down your logo while maintaining crisp, sharp contours.

Options Processing

If you customize settings, the canvas modifies the rendering stack. Toggling off transparency paints a solid background layer, and rounded corners apply a circular clipping mask over the bounding box.

Binary ICO Compilation

A multi-size .ico file is compiled directly in your browser. The script allocates memory headers, writes the ICO directory entry parameters, and concatenates raw PNG data streams using byte-level writer tools.

ZIP Compressing & Download

The files and site.webmanifest schema are loaded into a virtual folder using JSZip. The browser builds the package locally, registers a temporary URL reference, and triggers a prompt to save the ZIP.
