How to Use Favicon Generator
Follow these steps, then review the result and the limitations below:
- Select a supported static image with a clear subject.
- Choose 16, 32, 48, 64, 128 or 256 pixels from Favicon Size.
- Click Process Image and inspect the tiny preview before downloading the PNG.
- Reference the PNG from your own website markup, using its actual location and size.
Practical Worked Example
A 120 × 60 image exported at 32 pixels becomes a 32 × 32 PNG. The image occupies 32 × 16 pixels and is centered with transparent padding above and below.
Key Features & Capabilities
- Task-specific controls with labelled fields and status feedback.
- Processing uses browser APIs without a tool upload request.
- Invalid input is reported before a successful output is offered.
Generate a square PNG favicon with transparent padding
Choose a size appropriate for your icon placement. A non-square source is fitted inside the square without stretching or cropping; the remaining area is transparent. The output is a PNG favicon, not an ICO file.
How It Works (Technical Overview)
The browser calculates the smaller scale needed to fit the source inside the square canvas. It draws the scaled image centrally and exports PNG.
Real-World Use Cases & Applications
- Generate a square PNG favicon with transparent padding. Check the worked example before processing your own input.
Privacy, Security & Accuracy
Detailed photographs and small lettering can be unreadable at 16 pixels. This tool does not create ICO bundles, application manifests, every platform icon size or a complete site icon installation. Practical limits depend on browser support and available memory. Files above 20 MiB are rejected; raster processing is limited to 16 million pixels and output dimensions to 8192 pixels per side.
Pro Tips for Best Results
Check the result against your original and the requirements of the destination. Keep an unchanged source copy.
Frequently Asked Questions
How do I use the PNG?
Upload it to your site and reference it with a link rel="icon" element whose href points to the file and type is image/png. Check the deployed path and browser cache if an older icon remains visible.
Is my input uploaded for processing?
The tool code works in the browser. The page can also load advertising or analytics scripts, which have separate data practices. Avoid sensitive files on an unsuitable device or page.
