Inndataformat

PNG image

PNG is a lossless image format that can keep transparent pixels. A square source image gives the most predictable icon result without stretching or cropping.

Utdataformat

ICO icon

ICO is the icon format commonly used by Windows applications, shortcuts, folders, and favicon.ico files.

How to convert PNG to ICO

Upload the full-resolution PNG you have. Convertr creates one ICO image and scales it down proportionally only when a side is larger than the ICO format maximum of 256 pixels.

  1. 1 Upload a PNG image. Each file can be up to 1 GB.
  2. 2 Choose ICO as the output format and start the conversion.
  3. 3 Download the converted ICO file when processing is complete.

The converter does not crop or add padding. A non-square PNG stays non-square, so crop or resize it to a square first when the icon must fill a square canvas.

Create the right ICO file from a PNG

Choose a clean source image and the workflow that matches where the icon will be used.

Keep transparent backgrounds

Transparent pixels in the PNG remain transparent in the ICO output. An opaque PNG produces an opaque icon.

Start with a square PNG

Square artwork avoids a wide or tall icon. Common source sizes include 16×16 or 32×32 for browser icons, 48×48 for Windows icons, and 256×256 for a larger Windows icon.

One image per ICO file

This converter writes one image into the ICO file. It keeps source dimensions up to 256×256 and scales larger images proportionally so the longest side is 256 pixels.

Need a complete favicon set?

Use the favicon generator when you need a multi-size favicon.ico, browser PNG icons, Apple touch icons, Android icons, and a web manifest snippet in one download.

PNG to ICO FAQ

Does PNG to ICO conversion preserve transparency?

Yes. Transparent pixels in the source PNG remain transparent in the ICO output. An opaque source remains opaque.

What size will the ICO file be?

The ICO contains one image at the PNG dimensions when both sides are 256 pixels or smaller. Larger PNGs are scaled down proportionally so the longest side is 256 pixels.

Does the ICO contain multiple icon sizes?

No. This PNG to ICO converter writes one image into each ICO file. Use the favicon generator when you need a multi-size ICO and a full website icon set.

Can I convert a non-square PNG to ICO?

Yes. The output keeps the source aspect ratio and does not crop or add padding. For a conventional square icon, crop or resize the PNG to a square before converting.

Can I use the ICO as a Windows icon or favicon?

Yes. ICO files are commonly used for Windows shortcuts, folders, desktop applications, and favicon.ico. The application or website still needs to reference or install the downloaded file.

Is this PNG to ICO converter free?

Yes. Convertr is free to use with no registration or software installation. Uploaded files are processed for conversion and automatically deleted afterward.

What happens when PNG becomes ICO

Kjeldeformat

PNG uses lossless compression and supports full transparency.

Målformatet

ICO is the image source or target format for this conversion path.

Hva forandring

The PNG pixels are decoded and written using ICO compression and color capabilities.

Hva er bevaret
Pixel dimensions and visible composition are preserved unless resize or crop settings are selected.
What may be lost
ICO cannot preserve transparency. Transparent pixels must be flattened against a background color.
Codec and quality implications
Color profile handling, bit depth, chroma sampling, and compression settings can change appearance or file size.
Realistic limitations
Multi-page, layered, animated, camera-raw, or very large images may be flattened, reduced to one frame, or rejected if the decoder cannot safely read them.

Konverteringsprosesser

  1. Upload a PNG file no larger than 1 GB.
  2. Confirm that ICO is selected as the target.
  3. Start the conversion. A healthy compatible worker begins processing immediately.
  4. Download the ICO file and check the result before deleting your source.

Problemer løst

The PNG file is rejected or will not open.
Confirm that the file is not empty, password-protected, or corrupt and that its real format matches the extension.
The ICO file is larger than expected.
Choose a more efficient codec or lower quality setting when available. Lossless and uncompressed targets are often larger by design.
Transparency, color, or animation changed.
Choose a target that supports the needed feature and keep the original file; JPG cannot store transparency or animation.

Privatliv og filbevaring

Uploads and converted files are processed automatically and irreversibly deleted within 24 hours. You can delete them sooner with the delete control. Convertr does not read, mine, sell, or manually review file contents.
