Product Introduction

1. favicon.run is a specialized web tool designed to extract and deliver website favicons through URL input, providing embeddable code for immediate use. It automates favicon detection across multiple formats and sizes while eliminating manual code inspection or image editing. The service supports developers, designers, and marketers in streamlining asset retrieval workflows.
2. The core value lies in its ability to reduce time spent manually searching for and resizing favicons, offering technical users a one-stop solution for icon integration. By automating format detection and code generation, it ensures compatibility across browsers and platforms. This tool bridges the gap between raw website data and production-ready assets.

Main Features

1. The tool automatically detects all available favicon sizes (16x16 to 256x256 pixels) through URL analysis, including Apple Touch Icons and Microsoft Tile images. It parses HTML meta tags, HTTP headers, and default /favicon.ico paths to ensure comprehensive detection. Users receive a complete list of discovered icons with dimensions and format details.
2. Batch processing enables simultaneous extraction from up to 50 URLs in Pro plans, with parallel API requests to maintain speed. This feature includes error logging for failed attempts and CSV export capabilities. Enterprise-tier users get unlimited batch operations with priority queue positioning.
3. Embedded code generation produces responsive HTML tags or Markdown snippets optimized for different platforms. The system auto-selects the highest-quality icon version based on common use cases. Developers can toggle between absolute and relative path configurations in output code.
4. Format conversion allows downloads in PNG, ICO, SVG, or original formats (WebP/JPG) with optional resolution scaling. The converter preserves transparency for PNG/SVG outputs and adheres to ICO file specifications. Users can select specific dimensions before conversion through an interactive grid interface.
5. API integration provides RESTful endpoints with JSON responses containing icon URLs, dimensions, and formats. The Pro plan includes 1,000 monthly calls with rate limiting, while Enterprise offers 10,000 calls and custom authentication. API documentation covers error handling, caching parameters, and webhook configurations.
6. Priority processing accelerates favicon retrieval for paid users through dedicated server clusters, reducing average response time to <2 seconds. This feature guarantees service-level agreements (SLAs) for Enterprise clients during high-traffic periods. Real-time progress tracking is available for batch operations.

Problems Solved

1. Manual favicon extraction requires inspecting page sources, checking multiple file paths, and testing different resolutions—a process consuming 15-30 minutes per website. The tool automates this technical workflow into a 10-second operation with guaranteed accuracy. It solves version conflicts where different devices load inconsistent favicon sizes.
2. Primary users include frontend developers needing compliant favicon implementations for cross-browser support, and CMS administrators managing multiple client sites. Secondary users encompass technical writers embedding icons in documentation and QA testers verifying website assets.
3. Common scenarios involve updating legacy websites lacking proper favicon definitions, creating design system inventories, and generating social media previews requiring high-resolution icons. Marketing teams use it to maintain brand consistency when referencing partner websites in materials.

Unique Advantages

1. Unlike basic favicon checkers, this tool combines automated detection with developer-focused output options like embed codes and API integration. Competitors typically only display detected icons without conversion or code generation features. The service supports niche formats like SVG favicons that many tools overlook.
2. The multi-engine detection system employs three parallel methods: HEAD requests for favicon.ico, DOM parsing for tags, and manifest.json analysis for PWA icons. This triple-layer approach achieves 98.7% detection accuracy across 10 million tested domains. Custom algorithms handle edge cases like Base64-encoded icons and CDN-hosted assets.
3. Competitive differentiation comes from combining bulk processing with format conversion—a combination absent in free alternatives like favicon.io. The Pro plan's API offers more generous rate limits than similar services, while Enterprise SLAs guarantee 99.9% uptime. All paid tiers include malware scanning for downloaded icons, a unique security measure.

Frequently Asked Questions (FAQ)

1. How does favicon.run handle websites without a declared favicon? The system falls back to checking default paths like /favicon.ico and uses machine learning to identify potential icon files in /images directories. If no icons are found, it returns the highest-contrast 32x32px image from the site's root folder.
2. What happens when a website uses dynamically generated favicons? The tool captures the initial payload from static HTML but notes when icons are script-generated. Users receive a warning about potential client-side rendering issues and get options to force-capture the DOM-rendered favicon using headless browser technology.
3. Are extracted favicons cached, and for how long? All icons undergo 24-hour caching via CDN to ensure rapid subsequent requests, with cache invalidation triggers for updated favicons. Enterprise users can customize cache durations through API parameters and purge cached items on demand.
