Why Use PNG to ICO?

Brand Your Browser Tab

Recognisable in tabs, bookmark lists and history instead of a blank page glyph.

Show Up in Google

Google shows a favicon beside mobile search results — no icon means a generic globe.

CMS Wants favicon.ico

WordPress themes, older frameworks and hosting panels still expect a literal favicon.ico at the site root.

About PNG to ICO Converter

PNG to ICO Converter packages a single PNG into a multi-size .ico file — the format browsers traditionally expect for favicon.ico. Four sizes are selected for you (16, 32, 48 and 64 px) and each one becomes its own entry in the same file, so browsers can pick the right resolution for each context: tab, bookmark, search result.

Tick or untick sizes to change what goes in; 256 px is the ceiling, because an ICO directory entry has only one byte to describe a dimension. For best results use a square PNG with a transparent background — non-square inputs get padded. If you're designing a favicon from scratch instead of converting an existing PNG, the Favicon Generator builds the icon and the multi-size pack in one step.

Common Questions

The small icon that appears in browser tabs, bookmark lists and search results. Browsers fall back to a generic default if your site doesn't define one — leaving you looking unbranded next to every other tab.

You don't have to choose: the four sizes selected by default (16×16, 32×32, 48×48 and 64×64) all go into the same ICO file, and browsers pick whichever suits the context. Add 128×128 or 256×256 if you also want Windows Explorer's large-icon view to look sharp. 256 is the largest size the ICO format can describe.

Yes. Each size you tick is drawn from your PNG separately and written as its own entry in a single .ico, which is what makes the format worth using at all. Ship it as favicon.ico at your site root and one file covers every context.

A square PNG with a transparent background gives the best result. JPG works as a source but has no alpha, so it'll show a white square in dark-themed tabs and against dark UI chrome.

ICO is the most compatible because a single file holds multiple sizes browsers can select from. PNG favicons work in modern browsers but require separate <link> tags per size.

Not directly, this tool takes a PNG. If your logo is a vector SVG, rasterize it to a PNG at 256×256 or larger with SVG to PNG first, then drop that PNG here. Starting large keeps the 16 and 32px favicon sizes crisp.
