Making a Free Favicon for Blogger That Stays Sharp

Open twelve tabs in your browser and look at the tiny icons along the top. The ones you can identify instantly have something in common: a single bold shape on a solid background. The ones that look like a grey smudge are usually a full logo squashed into 16 by 16 pixels. If your blog is still showing the default orange Blogger icon, you are in the second group by default.

Making a free favicon for Blogger takes about half an hour with tools that cost nothing, and it is one of the few design changes that shows up everywhere at once: browser tabs, bookmarks, phone home screens and, increasingly, next to your blog's name in search results. Here is how to make one that stays sharp at every size.

What Size Your Blogger Favicon Should Be

A favicon is displayed at very different sizes depending on where it appears, so you design once at a large size and let it scale down.

A safe working size is a square canvas of 512 by 512 pixels, exported as a PNG and then resized to around 144 or 192 pixels for upload. Blogger caps the favicon file at 100 KB, and a simple icon at that size normally comes in well under 20 KB.

Designing an Icon That Survives 16 Pixels

The main challenge is not the software. It is restraint. At 16 pixels, you have roughly 256 dots to work with, and most of the detail in a normal logo disappears.

Use one or two letters, not a word

A single initial in a heavy font reads clearly. Three letters is the absolute limit, and only in a condensed bold typeface. Full blog names never work.

Pick a solid background

A filled square or circle in your main brand colour gives the icon an edge to hold onto. If you have not settled on brand colours yet, our roundup of free color palette tools for picking your blog colors will help you choose two that contrast well.

Check contrast in dark mode

Many readers now use browsers with dark tabs. A black letter on a transparent background vanishes completely. Either use a filled background or test the icon against both a white and a near black surface before you export.

Test it at real size before you export

Zooming in on a 512 pixel canvas hides every problem. Shrink a copy to 16 pixels, view it at 100 percent next to a few real browser tabs, and ask someone who has never seen your blog what letter or shape they see. If they hesitate, thicken the strokes or drop the detail. Expect two or three rounds; most first drafts have lines that are simply too thin to survive.

Why Your Logo Is Usually the Wrong Favicon

The most common advice is to "just use your logo". I disagree, at least for most bloggers using a free template.

Logos are designed to be read at header size, often 200 pixels wide or more, with a wordmark, a small symbol and sometimes a tagline. Shrink that to 16 pixels and you get noise. Big brands that appear to use their logo as a favicon have actually drawn a separate, simplified mark for small sizes.

The better approach is to pull one element out of your logo, such as the initial, the symbol or the main colour, and build the favicon from that alone. It still feels connected to your brand, but it is actually readable.

Free Tools That Do the Job

You do not need paid design software. Any of these categories will produce a clean favicon:

• Free browser based design editors with square templates, which are the fastest option for beginners
• Free open source image editors for raster work, good if you want pixel level control at small sizes
• Free vector editors, which let you design at any size and export crisp PNGs
• Free online favicon generators, which can turn a letter and a colour into an icon in under a minute

Whichever you use, export a PNG and compress it before uploading. The same free compression habits in our guide to preparing photos for Blogger with free tools apply to icons too.

Uploading It in Blogger Step by Step

1. Open your Blogger dashboard and go to Settings.
2. In the Basic section, find Favicon and click it.
3. Upload your square PNG, keeping it under 100 KB.
4. Save, then open your blog in a private browser window to see the new icon without cached files.

If the old icon still shows after a few minutes in a private window, the issue is almost always the template, not the upload.

Readers who have already visited may keep seeing the old icon for a while, because browsers cache favicons far longer than normal images. Clearing the browser cache, or removing and re-adding a bookmark, usually forces the new one to load on your own devices.

When a Free Template Overrides Your Favicon

Some free Blogger templates hard code a favicon link inside the head section of the theme, often pointing to the designer's own icon. That line wins over the dashboard setting, so your upload never appears.

To check, go to Theme, choose Edit HTML from the dropdown, and search the code for rel='icon' or rel='shortcut icon'. If you find a link pointing to an image you did not upload, back up the theme first, then delete that line. Make sure the theme still includes Blogger's standard head content tag, which is what inserts your dashboard favicon automatically. Save and recheck in a private window.

Frequently Asked Questions

How long does Google take to show my new favicon in search?

It can take anywhere from a few days to several weeks, because search engines recrawl favicons on their own schedule. Browser tabs update almost immediately, so check those first.

Can I use an animated GIF as a favicon?

Some browsers will show it, many will only show the first frame, and search results never animate. A static PNG is the safer and lighter choice.

Should my favicon match my template colours?

Ideally, yes. A favicon in your header colour makes the tab and the page feel like one brand, which helps returning readers spot your blog among open tabs.

The Practical Takeaway

Design a one or two letter icon on a solid square at 512 pixels, test it at 16 pixels against light and dark backgrounds, then upload a compressed PNG through Settings. If it does not appear, look for a hard coded icon line in your template. For more no cost design help, browse our free resources for bloggers.
