Astro favicon size

Client

Astro still needs square favicon pixels—public/favicon.svg or PNG. Upload below and export the size your theme or builder expects.

We read width and height locally, then resize with center crop. Max 8 MB.

HTML link tags

Set the folder where PNGs will live (site root is /). Copy tags into your document <head>.

Current export (32×32)

<link rel="icon" type="image/png" sizes="32x32" href="/favicon-32x32.png">

Full favicon block

Export size

?

Choose the pixel size your HTML link, manifest, or platform expects. Preview shows how center crop will look at that size.

Common use cases

  • Prepare Astro favicon PNG without leaving the browser.
  • Confirm Astro favicon requirements before updating HTML link tags or a CMS upload field.
  • Export a square PNG locally after upload—no server processing of your logo.

Common mistakes to avoid

  • Using a non-square logo without padding

    Center crop helps but cannot fix edge-to-edge text. Add margin before export.

  • Uploading a wide banner logo without square crop.

FAQ

What favicon size does Astro use?

Check Astro docs; public/favicon.svg or PNG is a practical export target.

Can I export the PNG in my browser?

Yes. Upload your image, pick the target pixel size, and download—processing stays on your device.
