Keep backups before major updates.

What is Favicon generator

Favicon generator helps when you have an image logo but you still don’t have a usable favicon file for a browser tab. Many sites and tools want a .ico file, and an image that looks fine at full size can turn into a blurry dot when it shrinks.

The free Favicon generator by FlexiTools.io converts an uploaded image into favicon (.ico) format on the same page. In under 60 seconds, you can drag and drop a JPG, PNG, GIF, or SVG (up to 5MB), choose a size like 16×16 or 32×32, preview the result, and download the favicon file. Why guess what it will look like in a tab when you can preview it first?

How to Use Our Favicon generator

  1. Add your image in the upload area that says Drag & drop your image here or click to browse, or click Browse Files. If the file is accepted, the Preview section shows your Original image and a Favicon Preview.

  2. If something is wrong with the upload, look at the error message area below the upload box. Fix the issue (like file type or size), then try again with a supported file under 5MB.

  3. Under Choose Size, select a radio option: 16×16, 32×32, 48×48, or 64×64. The selected size is clearly marked, so you can confirm what you’re about to download.

  4. Click Download Favicon. The button starts disabled and becomes available once the tool has a valid image to convert. Save the downloaded .ico file and use it where your site or project expects a favicon.

Why FlexiTools.io Offers the Best Favicon generator

Upload matches real habits

You can drag and drop an image or use Browse Files. Both options are visible on the same upload card. That helps when you’re moving fast and already have a file open in a folder.

File support is spelled out before you start

The upload note lists what’s accepted: JPG, PNG, GIF, and SVG, with a 5MB limit. This saves time. You don’t have to discover limits by trial and error.

Preview removes doubt

The Preview section shows Original and Favicon Preview side by side. You can catch issues like tiny text, thin lines, or a logo that becomes unrecognizable at small size before you download.

Size choice is explicit

Instead of guessing which size you’ll get, you pick it under Choose Size using radio buttons. 16×16 is selected by default. That makes the tool feel predictable.

  • This tool: Upload image, see two previews, pick 16-64 size, then download a .ico file.
  • Typical alternatives: No favicon preview, unclear size output, or pages that hide the size setting behind extra steps.
  • A common frustration avoided: Downloading an icon that looked fine in a large preview, then realizing it’s a mushy blob at 16×16.

A Deeper Look at Favicons and Size Choices

A favicon is the small icon you see in browser tabs, bookmarks, and some shortcut lists. It is tiny by design. That’s why it needs different thinking than a logo on a homepage. A clean logo at 1000 pixels can become unreadable at 16 pixels.

Why the tool focuses on .ico output

The page subtitle tells you what it does: it converts an image to favicon (.ico) format. The .ico format is widely used for favicons, and many setups still expect it. If your workflow asks for “favicon.ico,” this tool is aimed at that exact moment.

Start by looking at your source image, not the output

Before you even choose a size, check your original image in the Original preview. Look for details that will not survive shrinking, like thin outlines, small text, or tight spacing. If your logo has a long wordmark, it can become a gray line in a small square.

What each size is good for

The tool offers four sizes in Choose Size: 16×16, 32×32, 48×48, and 64×64. Think of these as “how much room do I have to communicate?”

16×16 is the strict test. It’s common in tabs, and it punishes detail. If your icon works at 16×16, you’re usually safe. 32×32 gives you more breathing room and often looks cleaner on high-resolution screens. 48×48 and 64×64 can help for places that show larger icons, or when you want a bit more clarity.

How to judge the favicon preview

The Favicon Preview is there for a reason. Use it like a checklist. Can you still identify the brand mark? Do the edges look jagged? Does the icon feel centered, or does it look like it’s falling off to one side?

If the preview looks cramped, your image may need more padding around the mark. If it looks fuzzy, the source may be too small, or the design may rely on fine detail. The preview helps you catch this early.

Why simple shapes win at small sizes

Favicons reward bold, simple shapes. A single letter, a strong symbol, or a clean silhouette often works better than a full logo lockup. Even if your brand uses text, the favicon is usually the mark, not the headline.

A realistic example from using the page

I once tried turning a wide header logo into a favicon. The original looked great. In the favicon preview, the text turned into a smudge, and the icon felt off-center. I swapped to an image version that used just the symbol, then picked 32×32. The preview finally looked like something I would recognize in a tab.

Why errors are part of the workflow

When you’re grabbing images from different places, you will occasionally hit a limit. This tool has a dedicated error message area. If you see an error, treat it as a quick filter: wrong type, too large, or not a usable image. The upload note is your guide for what the tool will accept.

How favicons are used on a page

If you’re adding the favicon to a website, it’s usually referenced in the page head. The details vary by setup, but the concept is consistent: you point browsers to your icon file. For practical guidance, see MDN documentation on rel="icon". For site-owner guidance on favicon requirements and how they may appear in search results, see Google Search Central’s favicon guidance.

Pro-Tips for Getting the Most Out of Favicon Creation

  • Use 16×16 as your reality check. If the icon is readable there, it will usually look fine at larger sizes. If it fails at 16×16, try a simpler source image.

  • Choose size based on where it will show up. For a browser tab, start at 16×16 or 32×32. If your use case shows a larger icon, test 48×48 or 64×64 and compare the preview.

  • Watch the edges in the preview. Jagged lines and tiny gaps are hard to see in a large logo, but obvious in the favicon preview. Pick the source image that holds up when shrunk.

What image files can I upload?
You can upload JPG, PNG, GIF, or SVG files. The upload note also shows a maximum size of 5MB. If the file isn’t accepted, check the error message area for what to fix. Then try again with a supported file.
Can I drag and drop an image?
Yes. The upload area says “Drag & drop your image here or click to browse,” and it works the way it reads on screen. You can also click the Browse Files button if you prefer. After a successful upload, the Preview section appears.
Why is the Download Favicon button disabled?
The Download Favicon button starts disabled so you don’t try to download before a valid image is ready. Once you upload an accepted image and the tool can generate a favicon, the button becomes available. If it stays disabled, check for an error message or try a different file. The preview area is a good signal that the file loaded.
What sizes can I generate?
You can choose 16×16, 32×32, 48×48, or 64×64 under the Choose Size section. The size is selected with radio buttons, with 16×16 checked by default. Pick the size you need, then download the .ico file. If you’re unsure, try 16×16 and check the preview.
What does the Preview section show?
It shows your Original image and a Favicon Preview side by side. This helps you judge how the icon looks when it’s reduced to a small square. Use it to spot blurry text, thin lines, or a mark that no longer reads. If the preview looks off, try a cleaner source image.
