SVG Logo Creator

Create professional, scalable SVG logos from concept briefs or descriptions.

Input Requirements

Before creating, gather or confirm:

• Text: Exact company/brand name and any tagline
• Logo type: Wordmark, lettermark, pictorial, abstract, combination, or emblem
• Visual concept: Core imagery, metaphor, or style direction
• Colors: Primary and secondary colors (hex values preferred)
• Typography direction: Modern/classic, geometric/humanist, bold/light

If working from a logo-ideation concept brief, these details should already be specified.

Creation Workflow

1. Plan the Design

Before writing SVG code:

• Sketch the basic shapes mentally
• Identify reusable elements (define once, reference with <use>)
• Plan the viewBox dimensions (typically 100x100 or proportional)
• Determine color palette as CSS custom properties

2. Create Primary Logo

Write clean, semantic SVG:

<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 200 60" role="img" aria-label="Company Name logo">
  <style>
    :root {
      --primary: #2563eb;
      --secondary: #1e40af;
      --text: #0f172a;
    }
  </style>
  <defs>
    <!-- Reusable elements here -->
  </defs>
  <!-- Logo content -->
</svg>

3. Generate Variations

Create these standard variations:

4. Save Files

Use consistent naming:

logo-primary.svg
logo-stacked.svg
logo-icon.svg
logo-wordmark.svg
logo-mono-black.svg
logo-mono-white.svg
logo-inverted.svg

SVG Best Practices

Structure

• Use viewBox for scalability, never fixed width/height
• Define colors as CSS custom properties in <style>
• Group related elements with <g> and descriptive id attributes
• Put reusable shapes in <defs> and reference with <use>

Optimization

• Remove unnecessary attributes (editor metadata, default values)
• Use simple paths over complex shapes when equivalent
• Combine adjacent paths of same color when possible
• Round coordinates to 1-2 decimal places
• Remove empty groups and unused definitions

Accessibility

• Add role="img" to root <svg> element
• Include aria-label with descriptive text
• Or use <title> as first child for accessible name

Typography in SVG

For text in logos, prefer:

1. Convert to paths: Most reliable across systems
2. Web-safe fonts: If text must remain editable
3. Embedded fonts: Only if absolutely necessary (increases file size)

Example text-to-path workflow:

<!-- Instead of <text>, use paths for reliability -->
<path d="M10 20 L10 40 L20 40..." /> <!-- Letter shapes -->

Example: Combination Logo

<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 200 50" role="img" aria-label="Acme Inc logo">
  <style>
    .icon { fill: #2563eb; }
    .text { fill: #0f172a; }
  </style>
  <defs>
    <g id="icon">
      <circle cx="20" cy="25" r="15" />
      <path d="M12 25 L20 18 L28 25 L20 32 Z" fill="#fff" />
    </g>
  </defs>

  <!-- Icon -->
  <use href="#icon" class="icon" />

  <!-- Wordmark (as paths for reliability) -->
  <g class="text" transform="translate(45, 20)">
    <!-- Text paths would go here -->
  </g>
</svg>

Delivery Checklist

Before finalizing:

• All variations created
• Colors match specification
• Scales properly from 16px to 1000px+
• Accessible labels included
• Clean, optimized code
• Consistent naming convention
• Tested on light and dark backgrounds

Usage Guidelines Output

After creating logos, provide brief usage guidance:

## Logo Usage

**Clear space**: Maintain padding equal to the height of the icon
**Minimum size**: 24px for icon, 80px for full logo
**Backgrounds**: Use primary on light, reversed on dark
**Don't**: Stretch, rotate, change colors, add effects
