ICO to WebP Converter

Drop a ICO, get a WebP. Nothing is uploaded.

Lower makes a smaller file and softens fine detail. 0.92 is what most tools use when they do not ask.

Resize

The shape is always kept, so the other side follows. Neither maximum ever ENLARGES a picture that is already smaller than it.

Pixels for either maximum, and a percentage for the last one. It is ignored while Resize is keeping the original size.

Nothing is uploaded. Your file is read in your browser and never leaves your computer.

What this does

A favicon generator, an icon editor or a Windows development tool writes ICO, and every website has one sitting at its root. A WebP is usually a third smaller than the same picture as a PNG or a JPG, which is why a website wants one. It turns up as the little square beside a page’s name in a browser tab, and as the picture on a Windows shortcut.

How it works

  1. Choose your ICO fileDrag a ICO file onto the box above, or press it and pick one. It is read in your browser, so nothing is uploaded.
  2. Wait for the WebPThe conversion runs on your own computer, so how long it takes depends on your machine and the size of the file, not on a queue.
  3. Download the WebPPress the download button. The WebP file lands in your downloads folder, ready for your slicer.

About the formats

Why your file is a ICO
Windows Icon. A favicon generator, an icon editor or a Windows development tool writes ICO, and every website has one sitting at its root.
Why you want a WebP
WebP. A WebP is usually a third smaller than the same picture as a PNG or a JPG, which is why a website wants one.
What a WebP holds
Either exact pixels or compressed ones, with transparency either way, in fewer bytes than both.
What changes on the way to WebP
The biggest square inside is taken; the smaller copies stored beside it stay behind, so what you get is one picture where the original was a set of them.
Where this format turns up
It turns up as the little square beside a page’s name in a browser tab, and as the picture on a Windows shortcut.

Questions

Is ICO to WebP Converter free?

Yes. Every tool on Short Work Tools is free, with no account, no sign-in and no limit on how many files you run through it. It runs on your own computer, so it costs us nothing to give away.

Is my file uploaded anywhere?

No. Nothing is uploaded. Your file is read in your browser and never leaves your computer. There is no upload step, no server copy and nothing kept afterwards, which is also why it works with the network switched off once the page has loaded.

What does the WebP keep from the ICO?

Either exact pixels or compressed ones, with transparency either way, in fewer bytes than both. The biggest square inside is taken; the smaller copies stored beside it stay behind, so what you get is one picture where the original was a set of them.

How large a file can I use?

Up to 250 MB. The limit is your browser's memory rather than an upload size, because the file never goes anywhere; a file larger than that is refused with a message rather than crashing the tab.

Which programs write ICO files?

A favicon generator, an icon editor or a Windows development tool writes ICO, and every website has one sitting at its root. It turns up as the little square beside a page’s name in a browser tab, and as the picture on a Windows shortcut.

Does the converted picture keep the information the camera wrote into it?

No, and there is no setting for it because there is nothing to set. The picture is decoded to pixels and drawn onto a fresh canvas, and a canvas has no place to put the camera model, the date or the GPS position the original carried, so none of it is in the file you get back.
