How to Add a Link to Your Tumblr Bio (2026 Step-by-Step)


TL;DR:
  • Tumblr blogs support up to 3 clickable links in the bio sidebar via Settings → Edit Appearance.
  • The Description field also supports HTML — meaning you can add unlimited inline clickable text links.
  • For multiple destinations behind one URL, use a link-in-bio service like UniLink.

How to Add Links to Tumblr Bio (Web)

  1. Open tumblr.com and log in.
  2. Click the account icon (top right) → choose your blog.
  3. Click Edit Appearance (gear icon).
  4. Scroll to Description — type your bio text and add HTML links.
  5. Or, find Customize → Theme → Add a custom link for sidebar links.
  6. Save.

How to Add HTML Links in Your Tumblr Description

The Description field accepts HTML. Examples:

<a href="https://unil.ink/yourname">My Links</a>

Or with line breaks:

Photography & Art
<a href="https://unil.ink/yourname">Portfolio</a>
<a href="https://shop.unil.ink/yourname">Print Shop</a>

HTML links display as clickable text in your sidebar.

How to Add a Theme-Specific Custom Link

Most Tumblr themes include 3 customizable sidebar links:

  1. Edit Appearance → ThemeEdit Theme.
  2. In the theme options, find Link 1, Link 2, Link 3 fields.
  3. Set:
    • Title — what it displays as.
    • URL — where it goes.
  4. Save.

These appear in the sidebar of your blog (location varies by theme).

How to Add Links via Tumblr Mobile App

  1. Open the Tumblr app.
  2. Tap your profile.
  3. Tap Edit (top right of profile).
