Favicon creation workflow
Create a favicon from your PNG in seconds
A good favicon needs several sizes so browsers, bookmarks, and high-DPI screens all look sharp. This workflow turns one square PNG into a single multi-size ICO file, generated locally in your browser.
Design, generate, deploy
Follow these steps to ship a favicon that looks right everywhere.
Prepare a square PNG
Use a 512 x 512 or larger square PNG with a simple, bold design and a transparent background.
Generate the ICO
Keep the multi-size option so the file contains 16, 32, 48, 64, 128, and 256 pixel entries.
Deploy the file
Download the .ico, upload it to your site root, and reference it with a link tag.
What a favicon set needs
- 16x16 and 32x32 icons for the browser tab
- A 180x180 apple-touch-icon for iOS home screens
- Optional 192x192 and 512x512 icons for app manifests
- A small, readable design at every size
Create the set in one pass
- 1
Open the PNG to ICO converter and load a square source image.
- 2
Generate the ICO with the required sizes.
- 3
Link the ico file in the site head and the PNG sizes in the manifest.
Favicon pitfalls to avoid
- A single 32 pixel icon looks blurry on high-DPI screens
- Busy designs become unreadable at 16 pixels
- Some tools output fake ICO files that browsers reject
- Uploading to a server defeats the privacy benefit of local generation
Favicon best practices
- Keep the design simple and high contrast
- Add padding so the shape does not touch the edges
- Check the icon in both light and dark browser themes
- Clear the browser cache after replacing the favicon
Frequently asked questions
What size should the source image be?
Use a square image of at least 256x256 pixels so downscaling to 16x16 stays sharp.
Can ICO files contain multiple sizes?
Yes. The tool embeds the requested sizes in one ICO file, which browsers pick from automatically.
Do I still need PNG icons for iOS?
Yes. iOS ignores ICO files and uses the apple-touch-icon PNG instead.
Is my image uploaded?
No. Conversion runs locally in your browser.
Private icon generation
PNG to ICO Converter renders and packs the icon locally in your browser. Your logo or artwork is never uploaded.
