Favicon & Manifest Generator

TLDR: Try my Favicon & Manifest Generator

To scratch a personal itch, I’ve rebuilt a tool for creating favicons and manifest files. This utility originally lived on a previous project, but I found it incredibly useful for quickly generating various icon sizes and a favicon.ico from a single source image. I’ve now rebuilt it (with a little help from Claude) and hosted it on my personal domain.

Beyond icons, the tool generates a customizable manifest.json file which is handy for Progressive Web Apps (PWAs).

For users logged in via my auth service, the tool maintains a history of previously uploaded icons. You can simply click an icon to rehydrate the manifest form values and regenerate the zip file download.

If you're interested in the code, check it out on GitHub: corenominal/favicons.philipnewborough.co.uk
