How big should favicon be

Favicon is a bitmapped picture with a pixel resolution. The standard icon size is 16×16 pixels. The standard size of a favicon is usually 24 by 24, 32 by 32, 64 by 64, etc. Google suggests that the size of the favicon should be a multiple of 48 pixels, e.g. 4848, 9696, etc. Apple products employ large icons that are 60×60 and 120×120 pixels in size. The maximum suggested size for a favicon is 256×256 pixels for Windows, 96×96 pixels for Linux, and 1024×1024 pixels for Mac OS X.


A favicon has always come in the ICO format as the standard. This format enables setting icon sizes with various bit sizes. The ICO is being replaced by PNG and SVG formats. Their benefits include light weight and excellent image quality. Other operating systems use PNG, but Safari MacOS uses the SVG format. Although the icon’s resolution is low, the ICO format is still in use. Icons can also be found in JPEG and GIF formats, but not all browsers support them. To check icons, use the caniuse.com service. The most common icon designs have solid fills and translucent backgrounds.

Favicon pixel size — Google Requirements

Google automatically indexes the icons on the website. Typically, indexing takes a few days. Indexing happens more quickly if the site is more well-known. Google prioritizes icons multiple of 48, content that is not obscene, coherence with the overall aesthetic, and distinctiveness. Google dislikes when photos are changed frequently.

Rules for Creating a Favicon

 There are some guidelines that should be observed when making a favicon:

  • Choosing the appropriate name. Selecting a proper extension, like.ico, is important. Both the file type and the file name must contain the specified format.
  • Cross-platform icon sets. Specific sizes and formats are provided for various platforms. The most desirable version among those uploaded is shown. You can use the service realfavicongenerator.net.
  • Including the address in the code in the <head> tag. Modern browsers automatically check the icon in the root directory, therefore this condition is not necessary. You can provide your own icons for the site’s various pages using the tag.
  • Examine indexing. In the robot.txt file, indexing should be permitted.
  • Verifying visibility. You must use search engine services to verify the icon’s accessibility.

Issues with Display

The following guidelines must be followed in order for a favicon to be displayed correctly: 

  • you should clear the cache and refresh the page;
  • check the format compatibility;
  • the code of the icon should be placed in the <head> block;
  • you must wait until indexing is complete;
  • you must allow indexing – replace disallow with allow;
  • unique favicons should be used, as non-unique icons are often ignored by search engines;
  • the display should not contain forbidden characters;
  • check the presence of the site in the filter SE.


A favicon is an emblem used on websites to improve their clickability and recognition. Icons are made using online tools (like favicon.by) or software like Adobe Photoshop. To ensure proper display by browsers, it is advised to create multiple icons at once. The icon needs to be easy to read and consistent with the brand profile.
