WebP to ICO Converter

Convert a WebP image into a Windows ICO icon holding 16, 32, 48 and 256 pixel versions. Transparency survives, which makes WebP a much better icon source than JPEG — though the two formats are separated by about thirty-five years and it shows.

Step by step

How to convert WEBP to ICO in 3 steps

  1. Add your WebP

    Still or animated; see below for what happens to animation.

  2. Nothing to configure

    All four standard sizes go into one file.

  3. Download your .ico

Format comparison

WEBP vs ICO

WebP

Lossy or lossless

A web format from Google that can work like JPG or like PNG, usually producing a smaller file than either.

  • Smaller files than JPG or PNG for most images
  • Supported by every current browser
  • Some older desktop software and upload forms still reject it

ICO (Windows Icon)

Multi-size icon

Bundles several sizes of the same small image in one file, for Windows icons and website favicons.

  • Several icon sizes in a single file
  • Understood by every browser as a favicon
  • Only for small images — each entry is at most 256 × 256 pixels

Two formats with nothing in common

WebP arrived in 2010 to make web pages faster, and it is genuinely good at that. ICO is a Windows container from 1985 whose internal images are stored as bitmaps or PNGs.

Nothing about WebP survives the trip except the picture itself: the image is decoded, rendered at each icon size, and stored in a form the container understands. Which is fine — an icon is sixteen pixels across, and no compression cleverness matters at that scale.

Transparency comes through

Unlike JPEG, WebP has a proper alpha channel and it is preserved. That matters more for icons than almost anywhere else: a browser tab may be light or dark, a taskbar may be any colour, and an icon with a baked-in white background announces itself as amateur on half of them.

Non-square images are centred on a square canvas with transparent padding rather than being stretched, so a wide logo keeps its proportions and gains no visible background.

Animated WebP gives you one frame

WebP can animate. ICO cannot — there is nothing in the container for a frame sequence, and no converter can change that.

You get the first frame. Usually that is fine, since an animation's opening frame is normally a sensible still, but an animation that fades in from nothing will hand you a nearly blank icon. Extract the frame you want first if it matters.

Animated favicons were briefly possible years ago via animated GIF and are no longer supported by any current browser, so there is nothing being lost that you could have used.

Lossy WebP has already made its compromises

Most WebP files on the web are lossy, and at the very small sizes an icon uses, any compression artefacts get averaged away to nothing. At 256 pixels they can still be faintly visible if the source was compressed hard. If you have the original artwork, use that — and if it is a vector, SVG to ICO gives a noticeably sharper result at small sizes.

Quality

Quality and file size

There is no quality setting. Each size inside the icon is stored losslessly; the only quality limit is whatever the WebP already had.

Use a source of at least 256 pixels

Every size is rendered down from your image, and sizes larger than the source are skipped rather than invented — deliberately, because an upscaled 256-pixel entry is blurry and Windows will happily prefer it over the crisp 48-pixel one. A small source therefore produces a smaller icon rather than a bad one.

The 16-pixel test

Look at the smallest size at actual size, on both a white and a near-black background. Almost every icon problem is invisible at larger sizes and obvious at 16 pixels: strokes disappear, text becomes a grey smear, and detail turns to noise.

If it fails, simplify the artwork rather than looking for a better converter.

For a website, this is not the whole job

An ICO alone stopped being sufficient years ago. The favicon generator takes the same source and produces the full modern set — the ICO plus the PNG sizes Apple and Android look for — which is what a site actually needs today.

Why you have a WebP in the first place

Almost always because it came off a website. Saving an image from a modern site frequently produces a .webp now, and design tools and build pipelines emit them by default for web use.

So the common situation is: you have a logo as WebP because that is what the site serves, and you need an icon for something that has never heard of WebP — a Windows shortcut, an installer, an older system, or a favicon.ico.

What ICO is still used for

  • /favicon.ico — browsers request it directly, without being told to, and so do feed readers, chat apps building link previews, and bookmark managers.
  • Windows application icons and desktop shortcuts.
  • Installers, which conventionally require ICO.
  • Folder and drive icons in Windows.

The multi-size trick is the reason it survives. One file carries several resolutions, so a tab takes the 16, a shortcut takes the 48, and a large tile takes the 256, each rendered for its size rather than scaled from a mismatch.

Where the file goes

At the root of your site as /favicon.ico, not in an assets folder. Browsers ask for that exact path on their own initiative, which is precisely why the file is still worth having even when your real icons are declared in HTML.

Going the other way

ICO to WebP pulls the largest image out of an existing icon and saves it as a WebP, which is how you reuse old icon artwork on a modern site.

What happens to your file

Browsers cannot write the ICO container, so this runs on our server. Your upload is deleted the moment conversion finishes, the result is deleted as you download it, and anything abandoned is swept automatically.

Privacy

What happens to your file

This tool runs on our server, so it works the same on every phone and computer. Your file is uploaded, and this is exactly what happens to it:

  • Stored outside the public web root under a random name, never under your file's name.
  • Processed, with the original upload deleted immediately — whether it succeeded or failed.
  • The result sits behind a signed link that only you receive, which stops working after 20 minutes, and the file is deleted the moment you download it.
  • Anything never collected is deleted automatically within 30 minutes.
  • The image itself is never logged or kept. If a conversion fails, we record the formats involved and the error — not the file.
  • Camera metadata, including any GPS coordinates recording where a photo was taken, is removed from the result. Only the rotation needed to show the image the right way up is kept.

Questions & answers

WebP to ICO: frequently asked questions

Is transparency kept?

Yes. WebP has a proper alpha channel and it comes through, which matters more for icons than almost anywhere else — browser tabs come in light and dark, taskbars come in any colour, and an icon with a baked-in white background looks wrong on half of them.

What happens to an animated WebP?

You get the first frame. ICO has no concept of animation and no converter can change that. An animation opening on a sensible still converts fine; one that fades in from nothing gives a nearly blank icon, so extract the frame you want first if it matters. Animated favicons are no longer supported by any current browser anyway.

What sizes are inside the file?

16, 32, 48 and 256 pixels. That multi-size ability is the reason ICO survives — a tab takes the 16, a shortcut the 48, a large tile the 256, each rendered for its size rather than scaled from a mismatch.

What if my image is smaller than 256 pixels?

Sizes larger than your source are skipped rather than invented. That is deliberate: an upscaled 256-pixel entry is blurry, and Windows would happily prefer it over the crisp 48-pixel one. You get a smaller icon rather than a bad one.

Will compression artefacts show?

Not at 16 or 32 pixels — anything that fine is averaged away. At 256 pixels they can be faintly visible if the WebP was compressed hard. Use the original artwork if you have it, and if it is a vector, SVG to ICO gives a noticeably sharper result at small sizes.

What happens to a non-square image?

It is centred on a square canvas with transparent padding rather than stretched, so a wide logo keeps its proportions and gains no visible background.
