How do I make a favicon?

Choose the ICO format. The tool generates a single .ico containing 16, 32, 48, 64, 128 and 256 px versions — exactly what browsers expect for a favicon.

Can I add or remove the background?

Yes. For PNG, WebP and ICO you can keep the background transparent or tick "Add a solid background" and pick a colour (white by default). JPG and BMP have no transparency, so a background colour is always applied. You can also tick "Make a colour transparent" to remove a solid background from a logo — pick the colour (or use "Pick corner") and adjust the tolerance.

Are my images uploaded?

No. Decoding, resizing, background compositing and encoding all happen in your browser. Your images never leave your device.

About the Image Converter

Different jobs need different image formats: a transparent **PNG** for a logo, a small **JPG** for email, a modern **WebP** for the web, or a multi-size **.ICO** for a website favicon. The AlarmDaddy Image Converter takes almost any image — including **SVG**, PNG, JPG, WebP, GIF, BMP and ICO — and converts it to the format you need, right in your browser. Nothing is uploaded.

A standout feature is **rasterising SVG**: vector logos and icons are turned into pixel-perfect PNG/JPG/WebP at the exact dimensions you choose. You also get full **background control** — keep transparency for formats that support it (PNG, WebP, ICO), or add a solid **background colour** (white by default) for formats that don't (JPG, BMP) or whenever you want a flat backdrop.

Need a favicon? Pick **ICO** and the tool builds a proper multi-resolution icon (16 to 256 px) in one file. Everything runs locally, so your images stay private.

How to use this calculator

1Choose or drag in an image (SVG, PNG, JPG, WebP, GIF, BMP or ICO).
2Pick the output format (PNG, JPG, WebP, BMP or ICO).
3Set the width/height (for non-ICO) and choose transparent or a background colour.
4Press Convert and download — e.g. a favicon.ico or a PNG from your SVG.

The formula

The image is decoded and drawn onto a canvas at your chosen size (optionally over a background colour), then re-encoded into the target format. ICO packs several PNG sizes into one icon file.

Raster formats (PNG/JPG/WebP/BMP) are produced by drawing your image onto an HTML canvas and exporting it; SVG is rasterised the same way, which is why you choose an output width and height. Formats with an alpha channel (PNG, WebP, ICO) can stay transparent; formats without one (JPG, BMP) are flattened onto the background colour. The ICO file is assembled by encoding the image at standard icon sizes and writing them into a single icon container.

Frequently asked questions

Yes. Drop in the SVG, choose PNG (or JPG/WebP), set the pixel size you want, and convert. The vector is rasterised crisply at those exact dimensions.
