Logo Tester

Your logo looks good on letterhead, but how does it work at 16 pixels in a browser tab, cropped into a circle as a profile picture or on a dark background? Upload your logo and see it right away in all the situations where it appears in everyday use. Finally, the tool creates all favicon files for your website, including the code.

A logo for every size

Whether a new logo or a careful refresh, we design brands that work from the favicon to the building façade. We look forward to hearing from you.

How the tool works

Upload your logo as SVG, PNG, JPG or WebP. If you have a separate signet for small sizes, meaning just the symbol without the wordmark, upload it as well. All previews are created live in your browser.

  1. 01

    Browser, Google and home screen

    You see your logo in a light and dark browser tab at 16 and 32 px, as a favicon in a Google search result and as an icon on a smartphone home screen. A size row from 16 to 64 px shows at which point details start to blur.

  2. 02

    Round icons and safe zone

    Android often crops app icons into a circle, and social networks show profile pictures as circles. The preview shows the safe zone and warns you if parts of your logo would be cut off.

  3. 03

    Light, dark and one colour

    Your logo appears on a light and on a dark background, with a warning if contrast is too low. There is also a black-and-white version and a one-colour version, as needed for stamps, engravings or embroidery.

  4. 04

    Background and padding

    Choose a background colour or keep the background transparent, and adjust the padding. With icons in particular, a little space around the symbol often makes the difference between cramped and confident.

  5. 05

    Favicon package as ZIP

    One click downloads all files: favicon.ico with 16, 32 and 48 px, icon.svg for an SVG logo, apple-touch-icon at 180 px, icon-192 and icon-512, a maskable icon for Android and the site.webmanifest. You also get the matching HTML code for the <head> of your website.

Why a logo must also work when tiny

Most people do not see your logo large on a poster, but small: in the browser tab, in bookmarks, next to your entry in Google search results or as an icon on their phone. There, a space of a few pixels decides whether your brand is recognised.

Fine lines, long wordmarks and subtle gradients get lost at these sizes. That is why strong brands have a reduced signet alongside the full logo that is still clearly recognisable at 16 pixels.

A one-colour version is just as important. A logo that only works in colour on white soon reaches its limits: on dark surfaces, on photos, in engraving or in screen printing on textiles.

A complete favicon package makes sure your website looks tidy on every device. Without it, browsers and smartphones show a grey default symbol or a blurry crop, and that looks unfinished.

Code for the <head>

<link rel="icon" href="/favicon.ico" sizes="32x32">
<link rel="icon" href="/icon.svg" type="image/svg+xml">
<link rel="apple-touch-icon" href="/apple-touch-icon.png">
<link rel="manifest" href="/site.webmanifest">

Place the files from the ZIP directly in the root directory of your website and add these lines to the <head>. In WordPress, it is easier to upload the icon in the Customizer under “Site Icon”.

Frequently asked questions about the logo tester

Which file format works best?

Ideally an SVG. It stays sharp at any size, and the tool also creates an icon.svg from it, which modern browsers prefer. A PNG with a transparent background and at least 512 × 512 px also works well.

What is a signet and do I need one?

A signet is the symbol of your logo without the wordmark, or a single distinctive letter. If your logo consists mainly of text, it almost always becomes illegible as a favicon. In that case a separate signet for small sizes is worthwhile.

What is a maskable icon?

Android places app icons in different shapes, such as a circle, a rounded square or a teardrop. A maskable icon has enough margin so that nothing important is cut off in any of these shapes.

Why does Google not show my new favicon yet?

Google does not update favicons immediately, it can take a few days to weeks. The icon must also be reachable at the address given in the head section of the page and must not be blocked by robots.txt.

My logo has too little contrast on a dark background. What can I do?

Create a light or all-white version for dark surfaces. For the favicon, a coloured background with some padding can also help, so the icon looks the same in light and dark browsers.

Is my input stored?

No. The tool runs entirely in your browser. Your input and files are neither transferred to us nor to third parties, and they are not stored. More in our privacy policy.
