Convert Image to ICO, Free and Online
This tool converts any image to a real .ico file, entirely in your browser — no software to install, no account, and no upload. It works the same way whether you're starting from a JPG to ICO conversion, a PNG to ICO conversion, or any other common image format. Search for image to ico converter, jpg to ico, or png to ico and you'll land in the right place: select your image, click convert, and download a genuine multi-size icon file.
It supports converting several images at once, too. Select multiple files and each one is turned into its own independent .ico file, with individual downloads for every result and a ZIP option if you're generating icons for more than one project at a time.
How to Convert an Image to ICO
Drop your image into the upload area, or click Choose File to browse for it — PNG, JPG, WebP, BMP, and GIF are all supported as source formats. You'll see a live preview the moment it's selected. Click Convert to ICO, then download your finished .ico file.
Behind the scenes, the converter builds a real multi-resolution icon container — 16×16 up to 256×256 — rather than just renaming your image file. Each size is generated from your source image with its aspect ratio preserved and no upscaling, so you get a sharp result at every size the source resolution actually supports.
Why Convert to ICO?
The .ico format is what browsers look for when displaying a website's favicon, and what Windows uses for application and shortcut icons — a PNG or JPG simply won't work in either of those places, no matter how the file is named. Converting a logo or image to ICO is a one-time step most people hit when setting up a new website or building a small Windows application, and it needs to be a real multi-size ICO container to display correctly across browser tabs, bookmarks, and Windows 10 or Windows 11's various icon sizes.
Non-Square Images and Transparency
If your source image isn't square, it's fit inside each icon size and centered, with transparent padding filling the rest — never stretched or squashed to force a square shape. If your source already has transparency (a PNG or WebP with a transparent background, for example), that transparency carries through into the finished ICO file, which is exactly what you want for a favicon that needs to sit cleanly on any background color.
Free, Private, and Genuinely Multi-Size
This image to ICO converter is free with no account, no watermark, and no limit on how many times you use it. Because everything runs locally in your browser, your logo or image is never uploaded anywhere — which matters if you're working with an unreleased brand asset or an image you'd rather not send to a third-party server just to generate a favicon.
Converting Several Icons at Once
Building out a full set of app icons or favicons for more than one project? Select every source image in one go rather than repeating the process file by file — each one is converted into its own independent .ico file, and a problem with one image won't affect the others. Once the batch finishes, download each icon individually or use the ZIP option to collect the whole set in one file, ready to drop into your project's assets folder.

Frequently Asked Questions
What is an ICO file?
ICO is a container format used for website favicons and Windows application/shortcut icons. Unlike a plain image file, one ICO can bundle several sizes of the same icon together.
How can I convert an image to an ICO file?
Upload your image using the tool above, click Convert to ICO, and download the result — a genuine multi-size ICO binary is built byte-by-byte in your browser, not a renamed copy of your image.
How do I convert a PNG image to an ICO file?
Select your PNG using the upload area above and click Convert to ICO — PNG is one of the supported input formats.
How do I convert a JPEG image to an ICO file?
Select your JPG or JPEG file using the tool above and click Convert to ICO — it's converted the same way as any other supported image format.
How do I save an image as an ICO file?
Upload the image, click Convert to ICO, then download the finished .ico file to save it wherever you need it.
How do I create an ICO image?
Select a source image, click Convert to ICO, and a genuine multi-size icon file is generated in your browser. A square image gives the cleanest result, but it isn't required — non-square images are fit inside the icon and centered with transparent padding, never stretched or distorted.
How do I make an ICO file from an image?
Upload the image using the tool above and click Convert to ICO — no software or account required.
What is the difference between PNG and ICO?
PNG is a general-purpose image format for a single image at a single size. ICO is a container built specifically for icons, able to bundle several sizes of the same image — 16×16 up to 256×256 — inside one file.
What type of file is used for icons?
The .ico format is what browsers look for as a favicon and what Windows uses for application and shortcut icons — a plain PNG or JPG won't work in either place.
Can I create an ICO file for free?
Yes — this tool is free with no signup, no watermark, and no limit on how many times you use it.
What image formats can be converted to ICO?
PNG, JPG, WebP, BMP, and GIF are all supported as source images.
What sizes can an ICO file contain?
Up to six standard sizes — 16×16, 32×32, 48×48, 64×64, 128×128, and 256×256 — generated automatically based on what your source image's resolution actually supports, without upscaling smaller images.
