About this tool

ICO to PNG, in the browser and without an upload. ICO is built for icons, so most editors and web platforms will not accept one, and ICO being the Windows icon container, which holds several small sizes of the same image in one file is exactly why that happens. PNG is a lossless format that keeps transparency, which is why logos, icons and screenshots are usually saved as one. Files usually come out a little smaller. Both formats are lossless, so every pixel survives the conversion exactly. Transparency survives the conversion intact, so cut-out logos and icons stay cut out. No upload and no account. The conversion runs on your machine, which means confidential files stay confidential and a slow connection makes no difference.

How to use this tool

  1. Add your ICO filesClick the box or drag ICO images onto it. Nothing is uploaded - your browser reads the files directly.
  2. Let it convertEach image is decoded and re-encoded as PNG on your device. A large batch takes a moment; nothing is queued on a server.
  3. Download your PNG imagesSave them one at a time, or take the whole batch as a single ZIP.

Key features

  • No sign-up, no watermark and no file-count limit.
  • Shows the before and after size of every file, so you can see what the conversion cost or saved.
  • Works offline once the page has loaded.
  • Batch conversion - drop a whole folder and convert it in one pass.
  • Converts ICO to PNG without uploading anything.

Common uses

  • Converting a batch of ICO files handed over by a client or a colleague.
  • Archiving ICO originals in a format you will still be able to open in ten years.
  • Preparing ICO images for a platform that rejects the format on upload.
  • Opening a ICO in software that only accepts PNG.
  • Getting ICO images into a document, presentation or email that refuses to embed them.

Tips for better results

  • Batch the whole folder in one pass - converting one file at a time is the slow way to do this.
  • Convert from the highest-quality ICO you have, not one that has already been resized or re-saved.
  • An ICO can hold several sizes at once. The browser picks the largest, so that is the one you get.

Mistakes to avoid

  • Renaming the file extension by hand instead of converting. That changes the name, not the data, and the file simply fails to open.
  • Expecting PNG to repair a low-quality ICO. Conversion changes the container, never the pixels already inside it.

Supported formats

  • ICO
  • PNG
