What belongs in a modern favicon package?
A favicon is no longer one tiny file beside your homepage. Browsers, search results, bookmarks, iPhones, Android launchers, and installed web apps each display your mark in a different frame. The useful baseline is still compact: a multi-size favicon.ico, a crisp SVG favicon when your source supports it, a 96-pixel PNG, an Apple touch icon, two web-app manifest icons, and the manifest itself.
Favicon Forge generates that exact set and gives every file a predictable production filename. The accompanying head snippet connects the package to your site without legacy tags or a folder full of redundant sizes.
Why does favicon.ico still matter?
SVG and PNG cover most modern interfaces, but favicon.ico remains the broad compatibility fallback browsers and desktop software know how to discover. This tool writes one ICO container with PNG-encoded 16, 32, and 48-pixel entries. That keeps tiny browser tabs sharp while avoiding the oversized “favicon kitchen sink” packages older generators create.
What makes an icon maskable?
Android can crop a web-app icon into a circle, rounded square, or another device shape. Important artwork placed too close to the edge may disappear. Favicon Forge measures visible source pixels against the standard centered safe circle before it labels manifest icons as maskable. If the artwork crosses that boundary, the tool says so and can add breathing room before export. The manifest only claims maskable when the rendered result actually passes.
Start with the best source you have
SVG is ideal because curves and edges remain clean at every output size. A 512-pixel or larger PNG, JPG, or WebP also works well. Smaller raster sources are accepted, with an honest warning wherever the browser must upscale them. Non-square artwork is centered on a square canvas and never stretched. Downscaling happens in measured steps instead of one large jump, preserving more edge definition at 16 pixels.
Private by design
Your source image is read into memory and processed with the browser Canvas API. The generated PNGs, ICO, manifest, SVG, and zip stay on this device until you download them. Favicon Forge has no account system, upload endpoint, or image analytics, and it does not save your artwork to local storage.
