ICO to PNG Converter
Pull the largest embedded image out of an ICO favicon or Windows icon file and save it as a standard PNG you can open and edit anywhere.
What Is ICO?
ICO is the file format used for website favicons — the small icon shown in a browser tab — and for Windows application icons. A single ICO file usually bundles several sizes of the same image together (16x16, 32x32, 48x48, and larger), so the browser or operating system can pick the size that fits.
Because an ICO file packs multiple images together in one binary container, it isn't something most image editors or photo viewers can open directly.
What Is PNG?
PNG is one of the most widely supported image formats, opening in virtually every app, browser, and operating system without any special software. It's also the format most image editors expect as input.
How This Tool Works
This tool reads an ICO file's internal structure, pulls out the largest embedded image, and saves it as a standard PNG — right inside your browser. Nothing is uploaded to a server. Drop in an ICO and get back a PNG you can open in any image editor.
ICO vs PNG — When to Use Each
| Feature | ICO | PNG |
|---|---|---|
| Multiple sizes in one file | Yes — several sizes bundled together | No — one image per file |
| Editing support | Not directly editable | Universal — every image editor supports it |
| General image use | Narrow — favicons and Windows icons only | Universal — photos, graphics, web images |
| Compatibility | Browsers and Windows only | Works everywhere |
| Best for | Browser tab icons, Windows app icons | Editing, sharing, general-purpose images |
Keep ICO When
- You're using the file as a website favicon or Windows app icon
- You need the multi-size bundling a browser or OS expects
Convert to PNG When
- You want to edit the icon's artwork in an image editor
- You need to reuse the icon's image somewhere other than a favicon or app icon
- You're extracting a logo from an old favicon to use as a fresh source image
- You want a single, standard image file instead of a multi-size bundle
Common Scenarios for ICO to PNG Conversion
Editing an Existing Favicon's Artwork
If you want to update or tweak a website's favicon but only have the old .ico file, extracting it as a PNG gives you a starting point you can open and edit in any image editor.
Recovering a Logo from an Old Favicon
Sometimes an ICO favicon is the only surviving copy of an old logo. Converting it to PNG lets you reuse that artwork as a source image for other assets.
Inspecting a Windows Application's Icon
If you're documenting or cataloging the icons used by a piece of software, extracting the ICO as a PNG makes it easy to view, resize, or include in documentation.
Rebuilding a Multi-Size Favicon
If you need to regenerate an ICO with additional sizes or a different format, extracting the current largest image first gives you a clean source to work from — you can then use our PNG to ICO converter to rebuild it.
Archiving Icon Assets
If you're archiving a project's brand assets and only have .ico files on hand, converting them to PNG keeps a copy in a format every future tool will be able to open. Our Hash Generator can produce a checksum afterward to confirm the archived copy hasn't changed over time.
Other Ways to Convert ICO to PNG
You can also convert ICO to PNG using your device's built-in photo viewer (File → Export or Save As), or an image editor like GIMP or Photoshop. FileCast is useful when you want a quick conversion without opening a separate app.
Frequently Asked Questions
Is it safe to convert my files here?
Yes. Your ICO file is processed entirely in your browser. Nothing is uploaded to a server, and nothing is stored after you leave the page.
Which image does the tool extract if the ICO has several sizes?
This tool extracts the largest image embedded in the ICO file, which gives you the highest-quality version available.
Does this work with any ICO file?
It works with modern ICO files, which embed a real PNG image inside the ICO container — the format used by every current favicon generator, browser, and operating system since Windows Vista. Very old ICO files that use a legacy uncompressed bitmap format instead of an embedded PNG are not supported.
Will transparency be preserved?
Yes. If the extracted icon image has a transparent background, that transparency carries over fully into the PNG.
Can I convert multiple files at once?
Currently, this tool converts one file at a time. Drop a file, convert it, download, then click "Convert Another" for the next one. Batch conversion is planned for a future update.
