Frequently Asked Questions (FAQ)
What is a PWA icon kit? Why do I need it?
A PWA (Progressive Web App) icon kit is a set of icon files needed to make a website look like a native app on mobile devices. It includes: favicon.ico (browser tab icon), favicon.svg (vector icon), apple-touch-icon.png (iOS home screen icon), android-chrome-192x192.png and android-chrome-512x512.png (Android home screen icons), and site.webmanifest (app manifest file). Modern websites need a complete PWA icon kit to provide the best user experience.
Why do I need SVG format Favicon?
SVG (Scalable Vector Graphics) format Favicon has the following advantages: 1) Vector format, infinite scaling without distortion, adapting to various resolution devices; 2) Small file size, fast loading; 3) Supports CSS styling and animation effects; 4) Modern browsers (Chrome, Firefox, Safari, Edge) all support SVG Favicon. It is recommended that modern websites prioritize SVG format while providing ICO format as fallback for older browsers.
Why do generated ICO files contain multiple resolutions?
The ICO file format supports embedding multiple resolution images in a single file, known as "multi-resolution ICO". Browsers and operating systems automatically select the appropriate resolution based on usage scenario: 16×16 pixels for browser tabs, 32×32 pixels for taskbars and favorites, 48×48 pixels for desktop shortcuts. A single multi-resolution ICO file is more efficient than multiple separate files, reducing HTTP requests.
How do I deploy generated icons to my website?
The downloaded ZIP package includes deployment instructions and code snippets. Basic steps: 1) Upload all icon files (.ico, .svg, .png) to your website's root directory, 2) Also upload the site.webmanifest file to the root directory, 3) Add the provided code snippet to the <head> section of your HTML file. In most cases, you just need to copy and paste the code. The tool-generated code already includes all necessary links and meta tags, including SVG and ICO priority settings.
Why isn't my website showing custom icons on iOS home screen?
If your website displays a webpage screenshot instead of a custom icon on the iOS home screen, possible reasons: 1) Apple Touch Icon file not correctly placed in root directory, 2) Incorrect apple-touch-icon link in HTML code, 3) iOS Safari cached old icon. Ensure all files are correctly deployed and try clearing Safari's website data. The code generated by this tool already includes all necessary apple-touch-icon links.
What are the best design practices for Favicons?
When designing Favicons, we recommend: 1) Use simple graphics or letters, avoid complex details (size is small), 2) Use high contrast colors for readability, 3) Maintain square design (circular designs display on square background), 4) Avoid thin lines (may not be visible at small sizes), 5) Test display effects on different background colors. The real-time preview feature of this tool can help evaluate design effects.
