ICO to PNG Converter - Convert ICO to PNG Online Free

Turn favicon and icon files into standard PNG images directly in your browser, with transparency preserved. Batch conversion, no uploads.

What ICO to PNG Conversion Does

This tool hands your .ico file to the browser's own image decoder, draws the decoded result onto a canvas, and re-encodes those pixels as a PNG. Nothing is uploaded — the entire cycle runs on your device. The part worth understanding before you start is that .ico is not really a single image. It is a container format, and a typical favicon.ico packs several separate bitmaps inside one file: 16×16, 32×32, 48×48, sometimes 256×256, so that an operating system or browser can pick whichever size fits the slot it needs to fill. A canvas decode does not work that way. The browser selects exactly one of those bitmaps — in practice the largest one it finds — and that single image is what gets drawn and re-encoded. So you get one PNG out of the conversion, not a set of PNGs covering every size the icon contained. If you specifically need the 16×16 variant that was sitting inside the file, this tool cannot pull it out separately; a dedicated icon extractor is the right job for that. Everything else about the conversion is straightforward. PNG is lossless, so the pixels the decoder produced come back out untouched, which is why there is no quality slider anywhere on this page. Transparency survives intact: nearly every icon has an alpha channel, PNG supports alpha, and the two line up exactly, so a transparent icon background stays transparent instead of turning into a white box. Nothing is upscaled either — the PNG comes out at whatever resolution the source bitmap actually was.

Why You'd Convert ICO to PNG

Usually because you have an icon in a format most software refuses to open, and you want a normal image file instead.

Open a site's favicon in editors and viewers that don't recognize the ICO container
Drop a logo mark straight into a design file, slide deck, or mockup
Keep the icon's transparent background instead of flattening it onto white
Convert a folder of collected .ico files into one consistent PNG set

How to Convert ICO to PNG

There is nothing to configure — PNG is lossless, so the only real decision is which files to run.

1

Add one .ico file or drop in several — the whole batch runs through the same pass

2

Apply the conversion; there's no quality slider, since PNG encoding has nothing to trade away

3

Check the preview and note the output dimensions — that's the one bitmap the decoder picked from the container

4

Download the PNG, or grab the whole batch as a single ZIP archive

Frequently Asked Questions

Yes. Almost every icon carries an alpha channel, and PNG supports alpha natively, so the transparency maps across without any flattening step. A rounded logo mark on a transparent background comes out of the conversion still transparent, ready to drop onto any color. This is the main reason to target PNG rather than JPG here — JPG has no alpha channel at all and would replace every transparent pixel with solid white.
No, and this is the one real limitation worth knowing up front. An .ico is a container that usually holds several bitmaps at different sizes, but the browser's decoder resolves it down to a single image before the canvas ever sees it. You get exactly one PNG per .ico file, not one per embedded size. Pulling out every variant separately requires a dedicated icon extraction tool, not a canvas-based converter.
Whichever bitmap the browser's decoder selects, which in practice is the largest one stored in the file. If your favicon.ico contains 16×16, 32×32, and 48×48 entries, you should expect a 48×48 PNG. There's no setting to override that choice — the selection happens inside the browser before the tool gets involved. The preview shows you the resulting dimensions, so you can confirm what you got before downloading.
Because the source was that small to begin with. Conversion re-encodes the existing pixels; it never invents new ones. If the largest bitmap inside the .ico is 32×32, the PNG is 32×32, and enlarging it afterward in any program will look soft or blocky. No converter can recover detail that was never stored in the file. For a sharp large version you need the original artwork, or a vector source such as an SVG.
Not on this page. Writing an .ico means building the container itself — generating multiple resized bitmaps and packing them into a single file with the right headers — and the browser's canvas encoder has no ICO output mode to do that. This tool only reads ICO and writes PNG. Creating a favicon from scratch needs a purpose-built favicon generator rather than a format converter.
No. The .ico is decoded and re-encoded entirely inside your browser using the canvas API, so the file never leaves your device. There's no upload step and no server-side storage. The practical consequence is that batch size is limited by your own memory and CPU rather than an upload cap, and the tool keeps working after you go offline as long as the page stays loaded.
Yes. Add as many as you like and they all run through the same pass. Because PNG has no quality parameter, there are no per-file settings to reconcile — each icon is simply re-encoded losslessly. Download the results one at a time or pull the whole batch down as a single ZIP. Icon files are small, so batches here run much faster than a comparable batch of full-size photographs.
Most sites still serve one at the root path — append /favicon.ico to the domain and save whatever loads. Some modern sites declare their icon elsewhere through a link tag in the page's HTML, or ship PNG and SVG icons instead of ICO, in which case there may be no .ico to fetch at all. Bear in mind that a logo you download this way is still someone's trademark, so check before reusing it.
