Frequently Asked Questions

What sizes do I need for favicons?
Modern websites need favicons in multiple sizes: 16x16 and 32x32 for browser tabs, 180x180 for Apple Touch icons, and 192x192 and 512x512 for Progressive Web Apps. This tool generates all common sizes automatically.
What image format should I upload?
A square PNG image of at least 512x512 pixels works best. SVG files also work well since they scale without quality loss. JPG images are supported but may show compression artifacts at small sizes.
What is a web manifest?
A web manifest (site.webmanifest) is a JSON file that tells browsers about your web app — its name, icons, and display preferences. It is required for Progressive Web Apps and helps browsers show the correct icon when users add your site to their home screen.

About Favicon Gen

What this tool does

Generator tools create passwords, UUIDs, Lorem Ipsum placeholder text, QR codes, barcodes, fake data sets, random numbers, and various code snippets. Each output is generated fresh on every click using cryptographic or pseudo-random algorithms.

Why use this tool

Developers and designers constantly need test data, unique identifiers, and placeholder content during prototyping. Generating them locally avoids dependency on external APIs and keeps sensitive outputs like passwords off the network.

How it works

For security-sensitive outputs (passwords, UUIDs), the tool uses the Web Crypto API's crypto.getRandomValues(). For placeholder text, it assembles words from a built-in dictionary. QR codes and barcodes are rendered to canvas or SVG.

Pro tip

For passwords, enable all character classes and use at least 16 characters. A passphrase of 4-5 random dictionary words is equally strong and much easier to remember.
