favicon.gg vs MumenLabs Favicon Generator

favicon.gg is a free browser toolkit for creating, converting, customizing, checking, and downloading favicons for websites, apps, and progressive web app projects. Its generator accepts images, text, emoji, or URLs, with image files up to 15 MB. One export can bundle multiple ICO sizes, an Apple icon, manifest icons, a web manifest, and HTML in a ZIP. The app-icon generator creates sets for web, PWA, iOS, Android, and desktop targets. Batch processing handles up to 40 files per run and places each image’s icons in its own ZIP folder. A converter works with PNG, JPG, WebP, SVG, GIF, and ICO files at selectable sizes. The checker scores favicon setups, explains issues, and supplies corrective code. An API returns a cached PNG for a domain at a requested size. Dropped images are processed in the browser; URL tools contact a server. No account is required, files are not retained, and generated icons belong to the user. Server-side tools are rate-limited per IP, and uptime is not guaranteed.
