Why Convert WebP to ICO?
WebP is built for serving images on web pages, not for icons. Browsers ask for a favicon at /favicon.ico and Windows expects .ico for application and shortcut icons, so a .webp file cannot fill either role no matter how small you make it. Converting to ICO wraps your artwork in the container those clients actually look for. It also forces the resize question early: a favicon is rendered at roughly 16 to 32 pixels, and artwork that reads clearly at 1200px often turns to mush at that scale. Converting first lets you see the icon at its real size and adjust the source before shipping it.

Frequently Asked Questions
How do I convert a WebP file to ICO?
Drop your .webp file onto the converter above, or click to browse for it. The output format is already set to ICO at 32x32, so you can press Convert straight away and download the .ico file. You can add up to 100 WebP files and convert them in one batch.
What size is the ICO file I get?
32x32 pixels, which is the standard favicon size and what browsers request most often. You can change the width and height in the converter settings before converting if you need a different size, such as 16x16 or 48x48. ICO cannot describe images larger than 256x256, so anything above that is scaled down to fit.
Is transparency preserved when converting WebP to ICO?
Yes. If your WebP image has an alpha channel, the transparent areas stay transparent in the ICO output. This matters for favicons because browser tabs render on light and dark backgrounds, and a baked-in white square will look wrong on one of them.
Does the conversion lose quality?
The ICO we produce stores its image data as PNG, which is lossless, so no compression artifacts are introduced during conversion. The quality slider does not affect ICO output for this reason. The only quality loss comes from scaling your image down to icon size — starting from a clean, high-contrast source gives the sharpest result.
What happens if my WebP image is not square?
It is scaled to fit inside the 32x32 box and centred, with the leftover space left transparent rather than cropped. Nothing is cut off, but a wide or tall image will end up small within the icon. For a favicon that fills the frame, crop your source to a square before converting.
How do I install the favicon on my website?
Download the .ico file, rename it to favicon.ico, and place it in your site's root directory. Most browsers find it automatically. To be explicit, add <link rel="icon" href="/favicon.ico" sizes="32x32"> inside your HTML head. On Next.js, putting favicon.ico in the app directory is enough.
Will this ICO work in older versions of Windows?
The file uses PNG-compressed icon data, which is read by every modern browser and by Windows Vista and later. Windows XP and earlier only understand BMP-encoded icons and will not render it. This is not a concern for website favicons, but it matters if you are building an icon for a legacy desktop application.
Do you upload my WebP file to a server?
No. The conversion uses the HTML5 Canvas API in your own browser, so the image is never transmitted anywhere. There is no account, no queue, and no file retention — closing the tab discards everything.
