ICO to PNG
ICO to PNG. Free, no signup, no watermark. Runs in your browser — your file never leaves your device.
How to ico to png
- Add your image — Drop it onto the box above, or click to open your file picker. On a phone this opens the camera roll directly.
- Set the options — Adjust the settings shown beneath the upload area. The defaults suit most files.
- Run the tool — Press the button. Processing happens on your device and normally finishes in well under a second.
- Download the result — Save the file. The original on your device is untouched — the tool never modifies what you put in.
What this tool does
To convert ICO to PNG, add your file to the tool above and the converted version is ready to download immediately. The image is decoded and re-encoded in the target format at full resolution, so no detail is lost to resizing. The tool is free, needs no account, applies no watermark, and has no daily limit.
What this tool does
Format conversion sounds trivial and usually is, until transparency or colour profiles are involved. This tool decodes the source image and re-encodes it in the target format at full resolution — no resizing, no quality drop beyond what the target format itself imposes. Where the target is JPEG, which has no alpha channel, transparent areas are flattened onto white rather than turning black, which is what a naive conversion does. HEIC files from an iPhone are decoded first, using a module that loads only when a HEIC file actually appears.
Why nothing is uploaded
This tool runs entirely on your own device. Your file is read into memory by JavaScript on this page, processed there, and handed back to you as a download. It is never transmitted to us, which means there is nothing on our side to store, log, leak or forget to delete.
You can verify that yourself: load this page, disconnect from the internet, and the tool still works. That is a different claim from a privacy policy promising prompt deletion, and it is the reason this site exists.
What it costs
Nothing. There is no account, no email capture, no free-trial countdown, no watermark on the output and no daily limit. The site is funded by advertising, which sits below the tool and never between an input and its result.
Supported formats
| Format | Accepted | Notes |
|---|---|---|
| JPG | Yes | Lossy; best for photographs. No transparency. |
| JPEG | Yes | Lossy; best for photographs. No transparency. |
| PNG | Yes | Lossless; supports transparency. Larger files than JPEG for photos. |
| WEBP | Yes | Smaller than both JPEG and PNG at similar quality. Supported everywhere current. |
| GIF | Yes | Limited to 256 colours. Only worth using for animation. |
| BMP | Yes | Uncompressed and very large. Convert it to almost anything else. |
| TIFF | Yes | Common in print and scanning workflows. Often multi-page. |
| AVIF | Yes | Smallest of the modern formats. Not decodable in every browser yet. |
| HEIC | Yes | Default on recent iPhones. Decoded to JPEG or PNG before processing. |
| HEIF | Yes | Default on recent iPhones. Decoded to JPEG or PNG before processing. |
| SVG | Yes | Vector, so it scales without loss. Rasterised when converting to a pixel format. |
| ICO | Yes | Windows icon container; holds several sizes in one file. |
Works offline
Because everything runs locally, this tool keeps working once the page has loaded even if your connection drops. That is worth knowing on a train, on conference WiFi, or anywhere the network is unreliable — and it is the clearest demonstration that your file really is not going anywhere.
