To convert ICO to PNG online, add your ICO files above, press Convert and download the PNG. By default the largest icon inside the file is exported; tick the option to export every size as its own PNG. Transparency is kept. Nothing is uploaded.
Convert ICO icon files to PNG to extract favicons and Windows icons as ordinary images. Export the largest size, or every size stored inside the file. It is a free tool from Websolindia, a New Delhi website design and SEO company that builds fast, image-optimised websites.
Unlike most online converters, this tool does not upload your images. Your browser decodes each ICO file, converts it and creates the PNG file on your own device. That keeps private photos private, avoids upload waits and keeps working on a slow connection once the page has loaded. You can convert up to 50 files at a time and download them one by one or together as a ZIP.

This table compares the two formats so you can decide whether converting is the right move.
| Feature | ICO | PNG |
|---|---|---|
| Full name | ICO (Windows icon) | PNG (Portable Network Graphics) |
| Origin | Microsoft's Windows icon format | W3C Recommendation in 1996 |
| Compression | Holds PNG or bitmap images | Lossless |
| Transparency | Yes | Yes, full alpha (256 levels of transparency) |
| Animation | No | No (animated PNG is a separate extension) |
| Colour depth | Up to 32-bit colour per image | Up to 16 bits per channel |
| Typical file size | Small | Large for photos, small for flat graphics |
| Best for | Favicons and Windows application icons | Logos, screenshots, graphics and anything needing transparency |
| Browser support | Every browser for favicons | Every browser, app and device |
| File extension | .ico | .png |
File size: PNG files from icons are small; the largest frame is usually the biggest file.
This is exactly what happens to your file. Nothing is hidden, and you can verify that nothing is uploaded by watching your browser's network tab while you convert.
| Step | What happens |
|---|---|
| 1. Read the file locally | Your browser reads the file from your device into memory. Nothing is sent to a server. |
| 2. Identify the format | We check the file's first bytes (its signature) instead of trusting the extension, so a PNG renamed to .jpg is still handled correctly. |
| 3. Decode the ICO to pixels | The image is decoded to raw red, green, blue and alpha pixels using our own icon reader, which handles PNG-based and older bitmap-based icons including their transparency mask. |
| 4. Resize (optional) | If you set a maximum width, larger images are scaled down with an area-weighted filter. Images are never enlarged, and the proportions are always kept. |
| 5. Keep transparency | Transparency passes straight into the PNG file, because PNG supports it. |
| 6. Encode the PNG | The pixels are written out as PNG using your browser's PNG encoder (lossless). Metadata such as camera details and location is not copied. |
| 7. Report the result | We show the dimensions, the sizes before and after, and the change: (new size − original size) ÷ original size × 100. For example, 500 KB becoming 350 KB is −30%. |
| Setting | Default | Range | What it does |
|---|---|---|---|
| Export every size | Off | On / Off | Off converts only the largest icon; On creates one PNG per size. |
| Maximum width | None | 1–20,000 px | Scales larger images down. Never enlarges. |
| What | Formula | Notes |
|---|---|---|
| Size change | (new − original) ÷ original × 100 | Shown for every file. Negative means smaller. |
| Downscale factor | min(1, maximum width ÷ width) | Applied only when you set a maximum width; never above 1. |
Speed depends on your device and the image size. In our Chrome tests on a desktop-class processor, a 6-megapixel photograph took about 2 seconds to convert to WebP or PNG. AVIF is the slowest: about 2.5 seconds on Fast and about 7.5 seconds on Balanced. Phones and older laptops take longer, and images over about 120 megapixels are declined rather than risking a frozen browser.
| Format | Where it opens | Typical use |
|---|---|---|
| ICO | Every browser for favicons | Favicons and Windows application icons |
| PNG | Every browser, app and device | Logos, screenshots, graphics and anything needing transparency |
| This converter | Current Chrome, Edge, Firefox and Safari. Needs JavaScript | Private conversion on your own device |
An icon file stores the same picture at multiple sizes, such as 16, 32, 48 and 256 pixels, so Windows and browsers can pick the sharpest one for each use.
Tick the option to export every size inside the icon. Each size is converted to its own PNG, named with its dimensions, and you can download them together as a ZIP.
Yes. Icons normally have transparent corners and soft edges, and the PNG preserves that.
Small icons contain only a few pixels. Enlarging them cannot add detail, so use the largest size in the file or redraw the icon at a higher resolution.
Yes. Use the PNG to ICO Converter Online to build a multi-size .ico file from any PNG.
Yes. Both modern PNG-based icons and older bitmap-based icons are supported, including the transparency mask they use.
Yes. It is free, needs no sign-up, adds no watermark and has no daily limit. You can convert up to 50 ICO files in one go. It is provided by Websolindia.
No. Your ICO files are read and converted inside your browser, on your own device. They are never sent to Websolindia or anyone else, which is why this converter is safe for private photos and documents.
Yes. The new file is created from the decoded pixels, so camera details, GPS location and other embedded metadata are not copied. If you need to keep metadata, use a desktop editor.
Up to 50 files per batch and 150 MB per file. Images above roughly 120 megapixels are declined with a clear message rather than freezing your browser.
Current versions of Chrome, Edge, Firefox and Safari.
