Favicon Generator
Make favicon sizes from one image and download each.
How to use Favicon Generator
Free favicon generator: upload a picture and get 16 to 512 px icons ready to host.
Open Favicon Generator on toolpermarket and fill in the inputs the tool asks for.
In the Image file field, choose a square source picture. A square image avoids awkward cropping; the tool scales to fit each size.
Press Generate sizes to compute the result. The output appears immediately below the form. Adjust the inputs and recalculate as many times as you need.
Read the result and use it as needed. If the number looks off, re-check your inputs and run it again — the math is deterministic, so the same entries always return the same answer.
Worked example. Load a 512 px logo, click Generate sizes, and download favicon-16.png through favicon-512.png to cover every device and browser.
Tips for accurate results.
Square sources scale cleanly to every size.
The 180 and 192 px versions cover Apple and Android.
Link the 16 and 32 px files in your page head.
When to use Favicon Generator. Producing a full favicon set from one image. Refreshing a site icon across devices. Meeting the sizes modern browsers request.
When you actually reach for this
- You need an icon for a website, app, or bookmark.
- You have a logo and want it sized for browser tabs and devices.
Where this tool stops being accurate
- Favicons are used at several sizes (16, 32, 48 px and more); a single size looks soft in some spots.
- Transparency support varies by format and platform; test how it sits on a browser tab.
Frequently asked questions
Is my image uploaded?
No. Each size is drawn from your source on a canvas in the browser and downloaded to your device; nothing is sent anywhere.
Do I need a square image?
It helps. A non-square source is stretched to fit each square size, which can look distorted; crop to square first for the best result.
Which sizes should I use?
16 and 32 px for classic tabs, 180 and 192 for phone home screens, and 512 for high-density displays — this tool emits all of them.
What size should my favicon be?
Provide at least 16, 32, and 48 px, or use an SVG/ICO that bundles multiple sizes, so it stays crisp in tabs and device lists.
