How to convert PNG to ICO

  1. Add your files. Drop PNG files anywhere on the page, or use Choose files. Folders and ZIP archives work too; every PNG inside is picked up.
  2. Check that ICO is selected. ICO is already chosen on this page. Other formats in the same row are one tap away if you change your mind.
  3. Adjust options if you need to. Adjust quality and size if you need to; the defaults keep the full resolution.
  4. Convert and download. Press Convert. Each file shows its progress, then a Download button. With several files, “Download all” gives you a single ZIP.

What happens to your PNG

Your browser decodes the image and draws it on a canvas, then it is saved in the new format. The icon contains 16, 32, 48, 64, 128 and 256 px versions, and non-square images are centred on a transparent square.

Converted files contain no EXIF metadata, so camera details and GPS location are removed, and photo rotation is applied to the pixels. A size option can scale large images down.

About PNG and ICO

PNG: PNG is lossless and supports transparency, which makes it the usual choice for screenshots, logos and graphics with sharp edges. Photos saved as PNG are much larger than JPGs.

ICO: ICO holds one or more square icons in different sizes. It is used for Windows icons and website favicons.

Questions

Is my PNG file uploaded anywhere?

No. The conversion runs inside this browser tab using code served by this site, and the ICO is created on your device. You can even disconnect from the internet once the page and its converter have loaded.

Will the ICO look the same as the PNG?

Yes, apart from what the ICO format itself allows: transparency is lost in JPG, colours are limited in GIF, and lossy formats compress fine detail at lower quality settings. Pixel dimensions stay the same unless you choose a size.

Can I convert several PNG files at once?

Yes. Drop as many PNG files as you like, a whole folder or a ZIP. They convert one after another, and “Download all” saves every ICO in one ZIP that keeps your folder structure.

Is there a file size limit?

There is no fixed limit, because nothing is uploaded. The practical limit is your device’s memory: a phone may struggle with very large files that a laptop converts easily.
