Favicon Generator vs Doing It by Hand
You can make a favicon by hand (design a square mark, export it at each size, convert one to .ico, and write the link tags) or let a generator produce the whole set and the markup in seconds. Hand-rolling is fine for a lone favicon.ico; a generator earns its keep the moment you also need the apple-touch-icon, Android sizes, a manifest, and matching tags, which are tedious and easy to get subtly wrong.
What 'by hand' actually involves
Doing it manually is a chain of small steps: design a square mark, export it at 16, 32, 48, 180, 192 and 512 pixels, bundle some of those into a multi-size .ico, write a manifest, and add link tags whose filenames all match. None is hard, but each is a place a mistake hides.
The .ico is the step that catches people. You can't just rename a PNG to .ico (it's a different container), so hand-rolling still needs a converter for that one file.
By hand vs generated
| Step | By hand | Generated |
|---|---|---|
| Sizes | Export each one | All at once |
| .ico file | Needs a converter | Done for you |
| Manifest | Write the JSON | Generated |
| Link tags | Write and match filenames | Provided |
Generator vs manual FAQ
Do I need a favicon generator?
Not for a single favicon.ico if you have a tool to make one. A generator pays off once you want the apple-touch-icon, Android and PWA sizes, a manifest, and correctly matched tags: the fiddly parts.
Can I make a favicon in Photoshop or Figma?
You can design and export the images there, but you still have to produce a real .ico and write the link tags and manifest yourself. The design tool does half the job.
Is a hand-made favicon lower quality?
No. It's the same files either way. A generator doesn't make a better favicon, it just removes the tedium and the small errors that come with doing it by hand.
