What Is an ICO File, and Why Convert PNG to ICO?
PNG to ICO conversion turns a PNG image into an ICO file, the icon format used for website favicons and Windows icons. One ICO file can contain several sizes (for example 16, 32 and 48 px), so the right size is shown in browser tabs, bookmarks, taskbars and desktop shortcuts.
An ICO file is a special image container made for icons.
Unlike a normal image, a single ICO can hold several versions of the same picture at different sizes. Software then picks the size that fits: a small one for a browser tab, a larger one for a desktop shortcut.
Common reasons to convert PNG to ICO:
- You are creating a favicon (favicon.ico) for your website or blog.
- You want a custom icon for a Windows app, shortcut or folder.
- A website builder, CMS or hosting panel asks for an ICO file.
- You are packaging a desktop program or tool and need an application icon.
- You want one file that works across browsers and older systems.
PNG vs ICO at a glance:
| PNG | ICO | |
|---|---|---|
| Purpose | General-purpose image | Icons and favicons |
| Sizes in one file | One | Several (16, 32, 48 and more) |
| Transparency | Yes | Yes |
| Used for | Web pages, graphics, design | Browser tabs, bookmarks, Windows icons |
| Compatibility | Everywhere | Browsers, Windows and many tools |
Good to know
- Start from a square image. Icons are square. If your PNG isn't, the converter centres it instead of stretching it, so it may have empty space around it. Crop it square first for the best result.
- Start big, shrink down. Use a square PNG at least as large as the biggest size you tick. A 512 px source gives clean results at every size. A tiny source can't be sharpened.
- Keep it simple. At 16 px, small details disappear. A bold shape, a letter or a simple logo mark works far better than a detailed picture or text.
What You Can Do With This Converter
- Pick your sizes. Tick any of 16, 32, 48, 64, 128 and 256 px. One ICO file holds every size you choose.
- Favicon-ready. 16, 32 and 48 px cover the standard favicon needs.
- Transparency kept. Transparent backgrounds stay transparent, so icons look clean on light and dark tabs.
- No stretching. Non-square images are centred, not distorted.
- Convert in bulk. Add up to 50 PNG files at once, each up to 100 MB, and download the results as a ZIP.
- Private by design. Images are processed in your browser and never uploaded to a server, which suits unreleased logos and client branding.
- Add images your way. Drag and drop, browse, or paste with Ctrl+V.
- No sign-up, no watermark, no fees.
- Works on any device. Windows, Mac, Linux, Android and iPhone, in any modern browser.

How to Add Your New Favicon to a Website
Step 1: Upload the file
Upload favicon.ico to the root of your website, so it is available at yourdomain.com/favicon.ico.
Step 2: Link it in your page head
Add this to the of your pages:
<link rel="icon" href="/favicon.ico" sizes="48x48">
Many sites also add a PNG or SVG icon alongside it for modern browsers, and an Apple touch icon (commonly 180 × 180 px PNG) for iPhones and iPads.
Step 3: Check it
Clear your browser cache, reload the page and look at the tab. Favicons are cached heavily, so it can take a while to update.
Using WordPress or a website builder?
Many platforms have their own "Site Icon" or "Favicon" setting and may ask for a larger square PNG instead of an ICO. Check what your platform asks for.
Does the favicon matter for SEO?
A favicon isn't a ranking factor by itself, but Google can show it next to your site in search results, especially on mobile, which helps people recognise your brand. Google's guidelines say the favicon should be a square image whose size is a multiple of 48 px (for example 48 × 48, 96 × 96 or 144 × 144), so including a 48 px size is a good idea.
Tips for a good favicon
- Use a simple, high-contrast mark. Avoid fine detail and long text.
- Make sure it looks good on both light and dark browser themes.
- Keep it consistent with your logo and brand colours.
- Keep your original PNG or SVG as the master.
Frequently Asked Questions
How do I convert PNG to ICO?
Open Teasoft's PNG to ICO converter, add your PNG, tick the icon sizes you need, click Convert to ICO and download the file or a ZIP.
What is an ICO file?
ICO is the icon file format used for website favicons and Windows icons. One ICO file can contain several sizes of the same image, so software can pick the right one.
What size should a favicon be?
Include 16, 32 and 48 px for standard use. Google recommends a favicon size that is a multiple of 48 px, so including 48 px is a good idea. Larger sizes such as 64 or 256 px can be added for sharper display or Windows icons.
Can one ICO file contain multiple sizes?
Yes. Tick as many sizes as you want and the converter packs them all into a single ICO file.
Does PNG to ICO keep transparency?
Yes. Transparent backgrounds in your PNG stay transparent in the ICO.
What happens if my image isn't square?
The converter centres it instead of stretching it, so it may have empty space around it. For the best result, crop your image square first.
What size should my source PNG be?
Use a square PNG at least as large as the biggest size you tick. A 512 × 512 px source works well for all sizes up to 256 px.
Why does my favicon look blurry or unreadable?
Favicons are very small, so detailed images and text lose clarity. Use a simple logo mark, and make sure your source image is large and sharp.
Why isn't my new favicon showing on my site?
Browsers cache favicons for a long time. Clear your cache, hard-refresh the page and check that the file is at the correct path and linked in your page head.
Can I convert many PNG files at once?
Yes. Add up to 50 PNG files in one batch, each up to 100 MB, and download the results as a ZIP.
Are my images uploaded to a server?
No. Conversion happens in your browser, and your files are never uploaded.
Is the PNG to ICO converter free?
Yes. It is free, with no sign-up, no watermark and no hidden fees.
