A tool built around one annoying, recurring task
AffiliateZephyr's favicon generator exists because setting up a proper favicon — one that actually looks right on iOS, Android, and every browser — kept turning into a bigger task than it should be: hunting down the right sizes, converting formats, writing the HTML by hand.
So we built a tool that does it all from one upload: every standard size, a proper multi-size .ico file, and the exact HTML code to paste in — nothing uploaded to a server, everything processed right in your browser. Alongside it, we write guides on the parts of favicon setup that aren't obvious until you run into them: caching issues, Apple's specific icon requirements, why a design that looks great full-size turns into a blur at 16 pixels.
We're a small team, and this tool is actively maintained. If something doesn't generate correctly, or you need a size or format we don't cover yet, we want to hear about it.

What we try to do differently
Everything in one step
Every size and format from a single upload, not one download at a time.
Nothing uploaded
Your image is processed locally in your browser using canvas.
Real .ico files
A proper multi-size ICO, not just a renamed PNG.
No account, no watermark
Free tools stay free, with nothing added to your icon.
