How to Convert PNG to ICO

Converting a PNG image to ICO is quick and easy with our free online tool. Simply drag and drop your PNG file (or multiple files for bulk conversion) into the upload zone — or click the "Browse Files" button to pick them from your device. The conversion runs entirely inside your browser using the HTML5 Canvas API, so your images are never uploaded to any external server. Once the conversion finishes, you'll see a preview of the resulting ICOs along with the original and ICO file sizes. Hit the download button (or "Download All" for batches) to save your images. No software to install, no accounts, and no waiting.

Why Convert PNG to ICO

PNG is perfect for logos and graphics with transparency, but browsers, Windows and many apps expect icons in ICO format. An ICO file bundles several sizes of the same image, so each place can use the one that fits best: 16 and 32 px for browser tabs and favicons, 48 px for Windows folders, and up to 256 px for desktop shortcuts and high-resolution screens. This converter creates every size from 16 to 256 px (up to the size of your original) and stores each one as a lossless PNG, so transparency and sharp edges are preserved. For the best result, start from a square PNG of at least 256×256 px. Need PNG favicons and the HTML tags for your site too? Try our Favicon Generator.

Is This PNG to ICO Converter Free?

Absolutely — this tool is 100% free with no hidden costs, no watermarks, and no conversion limits. Your images are processed entirely in your browser, so they remain completely private. Unlike many online converters that require you to upload files to a remote server, our tool never sends your data anywhere. It works on all modern browsers including Chrome, Firefox, Safari, and Edge, and it's fully responsive so you can use it on your phone or tablet just as easily as on your desktop computer.

Frequently Asked Questions

Is this PNG to ICO converter free?

Yes, completely free. No registration, no watermarks, no limits on conversions. Use it as many times as you need.

Will I lose image quality when converting PNG to ICO?

No. Every size inside the ICO is stored as a lossless PNG, so no compression artifacts are added and colors stay exactly the same. Smaller sizes are scaled down from your image, so for crisp icons start from a square PNG of at least 256×256 px.

Are my images uploaded to a server?

No. Everything runs in your browser using JavaScript and the Canvas API. Your files never leave your device. This is the safest and most private way to convert images online.

Can I convert transparent PNGs to ICO?

Yes, and the transparency is kept. Each size is saved as a 32-bit PNG with its alpha channel, so your icon keeps its transparent background in browser tabs and on the Windows desktop. Non-square images are centered on a transparent square.

Can I convert multiple PNG files to ICO at once?

Yes. This is a bulk PNG to ICO converter: select or drag and drop several PNG images and each one becomes its own ICO file. Download them one by one, or all together in a single ZIP file.

Which icon sizes does the ICO file include?

It includes 16, 32, 48, 64, 128 and 256 px versions of your image, up to the size of your PNG: a 64×64 px PNG gives 16, 32, 48 and 64 px icons, and a PNG of 256×256 px or larger gives all six. Images smaller than 16 px become a single 16 px icon.
