What does the Favicon Generator do?

The Favicon Generator from PowerSEOTools.online lets you upload a single image and generate multiple favicon sizes for browsers, tabs, bookmarks and app icons. You can preview each size, download PNG files and copy HTML link tags to add them to your website.

Which favicon sizes can I generate?

You can generate common favicon sizes such as 16x16, 32x32, 48x48, 64x64, 180x180, 192x192, 256x256 and 512x512 pixels. These cover standard browser favicons, high-DPI icons, Apple touch icons and Android or PWA icons.

Which file formats can I upload?

You can upload popular image formats such as PNG, JPG, JPEG and WebP. The tool converts your source image into square PNG icons at the selected sizes using client-side canvas rendering.

Are my images uploaded or stored on your server?

No. All favicon generation happens entirely in your browser using JavaScript and the Canvas API. Your images are not uploaded, stored or logged on our servers, which makes this tool safe for private and client projects.

Do I need an ICO file for modern browsers?

Most modern browsers fully support PNG favicons, especially when you include explicit link tags for each size. Many websites now use multiple PNG icons instead of a single ICO file. If you still need an ICO file, you can convert one of the generated PNGs with a dedicated ICO converter.

Options

File name prefix

Used for download names and HTML tags, e.g. favicon-32x32.png, favicon-192x192.png.

Public path (href)

Where you will upload the PNG files, for example / or /assets/icons/.

Icon sizes to generate

You can select as many sizes as you need. Smaller sizes are used in tabs and bookmarks; larger ones for home screens and apps.

Background

Fill background color (for non-transparent images)

If your source has no transparency, you can force a background color behind it in generated icons.

💡 Tip: Generate icons once, upload PNGs to your site, then paste the HTML snippet into your <head>.

PNG vs. ICO for Modern Websites

Modern browsers support PNG favicons very well, especially when you provide explicit <link rel="icon" ...> tags for each size. Many sites now use multiple PNG icons instead of a single ICO file. If you still need a classic favicon.ico, you can convert one of the generated PNGs using a dedicated ICO converter.

Fully Client-Side and Privacy-Friendly

All favicon generation is done directly in your browser using the Canvas API. Your images are never uploaded, stored or logged on our servers, which makes this tool safe for private projects, client work and internal branding.
