FAQ

Favicon Generator FAQs

What is the Favicon Generator tool?

It is an online converter for creating Favicon output from uploaded Image files.

How do I convert Image to Favicon?

Upload one or more files, adjust the available options, then start the conversion and download the result.

Can I upload multiple files?

Yes. Batch uploads are supported, and multi-file results are returned as a ZIP package.

Can I control output quality?

Quality controls are available for formats that support quality-based encoding, such as JPEG, WebP, AVIF, and HEIC.

Can I resize the image during conversion?

Yes. You can set width, height, or one dimension only to preserve the original aspect ratio.

Can metadata be removed?

Yes. The remove metadata option strips image metadata before writing the converted output.

Will transparency be preserved?

Transparency is preserved when the target format supports it. For JPEG/JPG output, transparent pixels are flattened onto the selected background color.

Can I force ZIP output?

Yes. Enable Force ZIP when you want a ZIP file even for a single converted image.

Does the converter change the original file?

No. The uploaded file is read for conversion, and the downloaded result is generated as a new file.

Can I use the converted image on a website?

Yes. Favicon output can be used anywhere that supports that image or document format.

Is there an API for this conversion?

Yes. Send a multipart POST request to /api/image-conversion/favicon-generator/convert with one or more files.

What happens if I upload the wrong format?

The endpoint validates the expected input format and returns an error when the file is not Image.

Can I use this for large batches?

Free conversion supports up to three files at once. Larger batch options are available with an upgraded plan.

What filename will the output use?

The converted file keeps the original filename stem and changes the extension to the Favicon output format.

Which settings should I start with?

The default settings are tuned for a balanced output. Increase quality or detail only when the use case needs it.
