If you are building a website, you will eventually need a favicon. While many modern setups use PNGs directly, ICO is still widely used for compatibility, especially for older browsers and Windows icon workflows.

Use: PNG to ICO.

What “favicon” files are used for

Favicons show up in more places than most people realize:

  • Browser tabs and bookmarks
  • The “recent sites” list on some browsers
  • Pinned shortcuts (depending on OS/browser)
  • Some RSS readers and link previews

Even a simple, clean favicon makes a site feel more polished.

Best practices before converting

For clean results:

  • Start from a square PNG (for example 512x512).
  • Keep enough padding around the logo so it doesn’t look cramped at small sizes.
  • Use a simple shape; tiny details disappear at 16x16.

Design tip: test at 16x16 early

The most common favicon mistake is designing something that looks great at 512x512 but becomes a noisy blob at 16x16.

A simple workflow:

  1. Design at high resolution.
  2. Shrink it to 16x16.
  3. If it still reads clearly, you are in good shape.

How to convert PNG to ICO (private)

  1. Open: PNG to ICO
  2. Drop your PNG file.
  3. Convert and download the ICO.

Where to use the ICO after converting

Most sites place the favicon at the site root. The exact setup depends on your stack, but a very common pattern is:

  • Put favicon.ico at the root of your public/static assets.
  • Reference it in your HTML <head> (or let your framework do it).

If you are using a modern icon setup (multiple PNG sizes, Apple touch icons, etc.), ICO is still a useful fallback for older tooling.

Quick sanity check

After you add your favicon, open your site in a couple of browsers and check:

  • Tab icon looks crisp at small sizes
  • The icon has enough padding (not cramped)
  • The icon still reads when scaled down

If it looks muddy at 16x16, simplify the design and increase contrast.

FAQ

  • Should I use PNG or ICO for my favicon? Many modern sites use PNGs (and other icon formats) in addition to ICO. ICO is still a good compatibility fallback.
  • What size PNG should I start with? 512x512 is a safe “source” size. The important part is that it is square and looks good when scaled down.
  • Is this private? Yes. QuickImager converts locally in your browser. No uploads.
