256×256 Favicon Generator
The 256×256 favicon size is one of the standard resolutions browsers and operating systems request. Use this tool to export a pixel-perfect 256px icon from any source image — PNG, JPG, or SVG — without losing quality.
A 256×256 icon is small enough to render quickly and large enough to stay legible at common UI scales. It's commonly bundled inside a multi-resolution .ico file alongside 16, 32, 48, and larger sizes.
For modern sites, a single multi-size favicon.ico containing 256×256 (along with 16, 32, and 48) covers virtually every desktop browser. Mobile and PWA users benefit from larger PNG/SVG variants linked via <link rel="icon"> tags.

Convertitore PNG in ICOFAQ
When do browsers request the 256×256 size?+
Browsers and operating systems request whichever resolution matches the current display density and target surface — tabs, bookmarks, taskbar shortcuts, or PWA install prompts. Bundling 256×256 guarantees a crisp render at that density.
Should I ship 256×256 as PNG or inside an ICO?+
Both. Older browsers and Windows shortcuts read .ico; modern browsers read PNG. The safest setup is a multi-size favicon.ico plus a separate <link rel="icon" sizes="256x256"> PNG.
Will upscaling a small logo to 256×256 look bad?+
Yes — upscaling adds blur. Start from a vector (SVG) or a source at least 256px on the longest edge. Use our SVG-to-PNG converter for the cleanest result.
