How to Add a Favicon in Blogger, Starting From Vector Logo Artwork

The short answer

To set a favicon in Blogger, open your blog's dashboard, go to the Layout section, find the Favicon element near the top of the layout editor, choose Edit, upload your icon image, and save. Blogger then serves that image as the small icon shown in browser tabs, bookmarks and history lists. If you are starting from a vector logo, export a simplified, square raster version for the upload, and keep the vector file as your editable master.

Two terms matter here. A favicon is the tiny site icon a browser displays next to the page title. A vector file, such as SVG, describes artwork as mathematical paths, so it scales without losing sharpness. A raster file, such as PNG, stores a fixed grid of pixels. Exporting a raster image from a vector file is called rasterizing.

Prepare the icon from your vector logo

A full logo rarely works at favicon size. Fine type, thin strokes and wide horizontal lockups turn into blurred pixels when shrunk to tab size. Before exporting, make a favicon-specific version of the mark in your vector editor.

• Use a square artboard, the defined canvas area that sets the export boundaries, so the icon is not stretched or cropped unpredictably.
• Reduce the logo to its most recognizable element, such as a symbol, monogram or single initial, instead of the full wordmark.
• Thicken thin strokes and remove small details that will disappear at small sizes.
• Check contrast against both light and dark browser themes, because the tab background varies between browsers and settings.
• Preview the artwork zoomed out to roughly tab size before exporting, and adjust shapes that merge or vanish.
• Export a square raster copy, typically PNG, for the Blogger upload, and keep the original vector file for future edits.

An .svg extension does not guarantee the file holds clean vector paths. Some SVG files contain an embedded raster image, which will not scale cleanly or edit like true vector artwork. Open the file in a vector editor and confirm that the shapes are editable paths. The extension also says nothing about whether you may reuse a logo. Confirm you have the right to use the mark before publishing it as your site icon.

Upload the favicon in Blogger, step by step

• 1. Sign in to Blogger and select the blog you want to update.
• 2. Open the Layout section from the left-hand menu.
• 3. Locate the Favicon element, usually at the top of the layout editor, and select Edit.
• 4. Choose your exported icon file and upload it. Read any file type or size requirements shown in the dialog.
• 5. Save the change.

Blogger's interface labels and layout can change over time, and different themes can arrange the layout editor differently. If you cannot find the Favicon element where described, look through the gadgets listed at the top of the Layout page.

Can you upload an SVG favicon directly?

This guide has no confirmed information on which file formats or file sizes Blogger's favicon uploader currently accepts. Use the requirements shown in the upload dialog as the authority. If the uploader rejects your SVG, upload a square PNG exported from it. A raster favicon is also the safer default when you need consistent display, because browser support for SVG favicons varies.

Some site owners declare an icon directly in their theme's HTML instead, using a standard link element in the page head. This works only if the image is hosted somewhere publicly reachable and the theme allows editing. Editing theme code can break a layout, so back up the theme first. The general form is shown below, with a placeholder where the hosted file address belongs.

<link rel="icon" type="image/png" href="YOUR-HOSTED-ICON-ADDRESS">

If the built-in Favicon element is available, use it instead. It is simpler and less likely to conflict with the theme.

Check that the new favicon is live

• Open your blog in a new private or incognito window, where an old icon is less likely to be cached.
• Force a full reload of the page if the previous icon still appears.
• Check the tab on both a light and a dark browser theme to confirm the icon stays legible.
• View the blog on a phone as well, because mobile browsers and home-screen shortcuts may display the icon differently.
• If the old icon persists, wait and check again later. Browsers often store favicons separately from page content and can be slow to update them.

What this guide could not confirm

No verified details were available on Blogger's current file format support, maximum upload size or recommended pixel dimensions for favicons. Check these against the upload dialog and Blogger's own help documentation before you finalize the artwork. The design advice above is general practice for small-scale logo use, not a documented Blogger requirement.
