If you've ever spent a weekend perfectly aligning the CSS grid on your new tech blog, only to realize the browser tab still shows a generic gray globe—your setup is incomplete. A custom favicon for personal blog sites is the easiest way to signal that you actually care about the details. Look at popular dev blogs like Dan Abramov's Overreacted or Cassidy Williams' site. They don't use complex corporate logos. They use a simple, recognizable face avatar or a clean initial.

I have a strong opinion on this: personal blogs should feel personal. Stop trying to design a Fortune 500 logo for your weekend thoughts.

Prerequisites for Your Icon

You just need a square, high-contrast image. A headshot with a removed background or a bold letter on a solid color works best.

Step 1: Pick the Right Image

I strongly recommend using your face if you write under your real name. It builds immediate trust and recognition in a crowded bookmarks bar. If you prefer anonymity, use a bold, single-letter SVG. Avoid full words or complex geometric shapes—they turn into illegible smudges at 16x16 pixels. (If you're trying to adapt an existing mark, read our guide on how to make a favicon from a logo).

Step 2: Generate the Minimal Stack

Personal blogs don't need a 30-file enterprise setup. You need exactly three things in 2026: an SVG (for modern browsers), a 180x180 PNG (for Apple devices), and a fallback ICO. Drop your image into Mzu favicondl, and we'll spit out exactly these optimized files. Don't waste time manually resizing images in Photoshop.

Step 3: Inject the HTML

Open your blog's <head> tag. Whether you're using Astro, Next.js, or a static site generator, paste this exact snippet:

<link rel='icon' href='/favicon.svg' type='image/svg+xml'>
<link rel='apple-touch-icon' href='/apple-touch-icon.png'>
<link rel='icon' href='/favicon.ico' sizes='32x32'>

Common Pitfalls to Avoid

Your blog is your digital living room. Don't leave the front door looking like a generic template. Grab a good photo, run it through the generator, and claim your browser tab. (For more on personal branding, check out our portfolio website favicon guide).
