create-icons logo.svg --color "#ff5733"
# Choose generation mode
create-icons logo.svg --mode nextjs # Next.js App Router (app/)
create-icons logo.svg --mode traditional # Traditional web app (public/)
create-icons logo.svg --mode auto # Auto-detect (default)

create-icons logo.svg -o ./app -m nextjs -c "#1a1a1a"
Generation Modes
The tool supports two generation modes for maximum compatibility:
š Next.js App Router Mode (--mode nextjs)
Perfect for Next.js 13+ with App Router
Generated files (in app/ directory):
favicon.ico(32Ć32)icon.png(512Ć512) - auto-linked by Next.jsapple-icon.png(180Ć180) - auto-linked by Next.jsapple-touch-icon.png(180Ć180) - for compatibilityicon.svg(if source is SVG) - auto-linked by Next.js
Benefits:
- ā Zero configuration - icons auto-linked by Next.js
- ā
No manual
<head>tags needed - ā Automatic metadata generation
- ā Cleaner project structure
Usage:
create-icons logo.svg --mode nextjs
# or let it auto-detect
create-icons logo.svg # detects Next.js App Router automatically
š Traditional Mode (--mode traditional)
Perfect for all other frameworks and traditional web apps
Generated files (in public/ directory):
favicon.ico(32Ć32)icon.svg(scalable)icon-192.png(192Ć192) - for PWAicon-512.png(512Ć512) - for PWAapple-touch-icon.png(180Ć180)icon-maskable.png(512Ć512, with padding) - for Androidsafari-pinned-tab.svg(monochrome) - for Safarisite.webmanifest(PWA manifest)
Requires: Manual HTML integration (copy from html-snippet.txt)
Usage:
create-icons logo.svg --mode traditional
Generated Files
Generated Files
Traditional Mode generates these files in your output directory:
/public/
āāā favicon.ico (32Ć32)
āāā icon.svg (scalable)
āāā icon-192.png (192Ć192)
āāā icon-512.png (512Ć512)
āāā apple-touch-icon.png (180Ć180)
āāā icon-maskable.png (512Ć512, with padding)
āāā safari-pinned-tab.svg (monochrome)
āāā site.webmanifest (PWA manifest)
/ (project root)
āāā icon-integration-guide.txt (HTML snippet to copy)
Next.js App Router Mode generates these files in your app directory:
/app/ (or /src/app/)
āāā favicon.ico (32Ć32)
āāā icon.png (512Ć512, auto-linked)
āāā icon.svg (scalable, auto-linked)
āāā apple-icon.png (180Ć180, auto-linked)
āāā apple-touch-icon.png (180Ć180, compatibility)
/ (project root)
āāā icon-integration-guide.txt (integration instructions)
Framework Detection
The tool automatically detects your framework and uses the correct output directory and mode:
| Framework | Config File | Default Mode | Output Directory |
|---|---|---|---|
| Next.js (App Router) | next.config.js + app/ |
nextjs |
app/ |
| Next.js (Pages) | next.config.js |
traditional |
public/ |
| Astro | astro.config.mjs |
traditional |
public/ |
| SvelteKit | svelte.config.js |
traditional |
static/ |
| Remix | remix.config.js |
traditional |
public/ |
| Vite | vite.config.js |
traditional |
public/ |
| Default | None detected | traditional |
public/ |
HTML Integration
Next.js App Router (Auto-Linked)
No manual HTML needed! Next.js automatically generates these tags:
<link rel="icon" href="/favicon.ico" sizes="any" />
<link rel="icon" href="/icon.png" type="image/png" sizes="512x512" />
<link rel="apple-touch-icon" href="/apple-icon.png" />
<link rel="icon" href="/icon.svg" type="image/svg+xml" />
Traditional Mode (Manual Integration)
After generation, copy the contents of icon-integration-guide.txt to your HTML <head>:
<!-- Favicon (modern + fallback) -->
<link rel="icon" href="/icon.svg" type="image/svg+xml">
<link rel="icon" href="/favicon.ico" sizes="any">
<!-- Apple Touch Icon -->
<link rel="apple-touch-icon" href="/apple-touch-icon.png">
<!-- Web App Manifest (PWA) -->
<link rel="manifest" href="/site.webmanifest">
<!-- Safari Pinned Tab -->
<link rel="mask-icon" href="/safari-pinned-tab.svg" color="#5bbad5">
AI Assistant Integration
After generation, the tool provides an AI-ready prompt you can use with Claude, ChatGPT, or other assistants to verify your setup:
I generated web app icons in the [directory] for this [framework] app.
Please read the integration guide at icon-integration-guide.txt and verify
that all icon files are correctly placed and properly integrated.
Requirements
- Node.js 18 or higher
- Source image in SVG, PNG, or JPG format
- For best results, use square SVG with transparent background
Supported Input Formats
.svgā Recommended (scalable, generates all files).pngā Good (generates raster icons, SVG files need manual creation).jpg/.jpegā Acceptable (generates raster icons, SVG files need manual creation)
How It Works
- Looks for
app-icon.svgorapp-icon.pngin current directory (or uses provided path) - Detects your framework (Next.js, Astro, etc.) and determines the best generation mode
- Auto-selects mode: Next.js App Router ā
nextjsmode, others ātraditionalmode - Converts & resizes your source image to all required sizes for the selected mode
- Generates maskable icon with proper 20% safe zone padding (traditional mode)
- Creates monochrome SVG for Safari pinned tabs (SVG sources only, traditional mode)
- Generates manifest with correct icon references (traditional mode)
- Outputs integration guide in
html-snippet.txt
Why This Tool?
Most icon generators are:
- ā Outdated (generate 30+ unnecessary files)
- ā Online-only (require uploading your logo)
- ā Not framework-aware (manual directory setup)
- ā Missing modern features (maskable icons, SVG favicons)
- ā Don't support Next.js App Router conventions
This tool:
- ā Generates only what you need (2025 standards)
- ā Works offline (CLI-based)
- ā Auto-detects your framework
- ā Includes modern PWA features
- ā Supports Next.js App Router with zero-config auto-linking
- ā Dual-mode support: traditional web apps + Next.js
Examples
Example 1: Zero Config (Recommended)
cd my-nextjs-app
# Create app-icon.svg in the project root
create-icons
# ā Found app-icon.svg in current directory
# ā Detected Next.js ā using public/ directory
# ⨠Success! Generated 8 files
Example 2: Next.js Project with Custom Path
cd my-nextjs-app
create-icons assets/logo.svg
# ā Detected Next.js ā using public/ directory
# ⨠Success! Generated 8 files
Example 3: Custom Output
create-icons assets/brand.svg --output static/icons
# Generated icons in static/icons/
Example 4: Brand Color
create-icons logo.svg --color "#ff6b35"
# Safari pinned tab will use #ff6b35
Browser Support
| File | Supported Browsers |

Troubleshooting
"Source file not found"
- Ensure the path to your source image is correct
- Use relative or absolute paths:
./logo.svgor/Users/you/project/logo.svg
"Invalid file format"
- Only SVG, PNG, and JPG are supported
- Convert other formats (WebP, GIF) to PNG first
Icons not displaying
- Ensure files are at domain root (
https://yourdomain.com/favicon.ico) - Check HTML
<head>tags are present - Clear browser cache (hard refresh: Cmd+Shift+R / Ctrl+Shift+R)

Usage with Claude
Ask Claude to help with icons:
- "Generate web icons for my Next.js project"
- "Check if my project has all required icons"
- "Create icons from logo.svg and add them to my HTML"
- "Add icon tags to my index.html file"
