What you get

PNG to ICO conversion that shows the actual layers before you download. The image is drawn into each selected canvas size with a transparent background, then packaged into one ICO file in your browser.

If you are looking for a PNG to icon converter, this page turns your PNG into one ICO file and lets you choose which size layers to include.

To change PNG to ICO, choose an image above and select the pixel layers for the finished icon. To convert PNG file to ICO, generate a real .ico output instead of changing the PNG filename. To convert PNG to ICO file, select the layers before downloading them together.

For a complete favicon package check of the linked HTML and manifest files, use the Favicon Generator.

To check whether downloaded ICO filenames map back to their submitted source images, use the ICO Converter.

Use this image to ICO tool with a PNG, JPG, GIF, or WEBP image, then download a single multi-size icon file processed in your browser.

  • PNG, JPG, GIF, and WEBP input your browser can decode
  • 16, 32, 48, 64, 128, and 256 pixel layers
  • Transparent pixels remain transparent
  • One download, with no account or server

How to change PNG to ICO

  1. 01
    Choose a file

    Drop one image into the tool or browse for it.

  2. 02
    Pick the layers

    Keep the defaults or choose the pixel sizes you need.

  3. 03
    Download the icon

    Click once to save a single multi-size .ico file.

To convert a PNG to an icon for a Windows shortcut or favicon, choose the ICO layers that fit its use. To convert PNG file to icon, use the generated .ico file rather than renaming the source image.

Repeatable file check · 2026-09-30

What a PNG-to-ICO download contains

A file-level comparison from one 64 × 64 artwork encoded as four PNG color types.

We converted grayscale, RGB, indexed-color, and RGBA versions of the same 64 × 64 test artwork with this tool and ConvertICO, then decoded the downloaded ICO files. Each output contained six layers (16, 32, 48, 64, 128, and 256 px); the decoded 64 × 64 layer matched the source pixels in all runs.

PNG input encodingInput bytesThis tool: ICO bytesConvertICO: ICO bytes
Grayscale (type 0)31614,762370,070
RGB (type 2)43914,762370,070
RGBA (type 6)45314,762370,070
Indexed color (type 3)1,03914,762370,070

Within each converter, all four variants produced the same output SHA-256 in this run. The size difference alone does not show which image looks better or whether a service retains uploaded files. No transparent pixels were present in these fixtures, so this run does not test transparency preservation.

Recheck the input and output measurements, decoded frame manifest, or original PNGs, ICO outputs, and SHA-256 list. See the color-type output report and ICO size and encoding report.

Live converter check · 2026-10-26

Three locally generated PNGs, decoded from the downloaded ICO

Each input was created locally, converted on this page, and read back from its downloaded ICO. The six directory entries decoded as PNG layers at 16, 32, 48, 64, 128, and 256 px.

Test 1 · alpha edge

Transparent RGBA PNG, 512 × 512, 7,985 bytes

The locally generated ring fixture produced an 18,657-byte ICO with 6 entries. Decoded 16 × 16 layer: 156 transparent, 80 partial-alpha, 20 opaque pixels. Decoded 256 × 256 layer: 49,612 transparent, 1,160 partial-alpha, 14,764 opaque pixels.

This fixture does not establish the output counts for every antialiased design.

Test 2 · opaque input

Locally generated two-color RGBA PNG, 512 × 512, 2,540 bytes

The downloaded ICO was 4,180 bytes with 6 entries. Its decoded 16 × 16 layer had 256 opaque pixels; its 256 × 256 layer had 65,536 opaque pixels, with no transparent or partial-alpha pixels.

This opaque fixture does not test transparency handling.

Test 3 · small source enlarged

Transparent 16 × 16 PNG with a centered 8 × 8 mark, 83 bytes

The downloaded ICO was 8,394 bytes with 6 entries. The 16 × 16 layer had 192 transparent and 64 opaque pixels. The 256 × 256 layer had 45,091 transparent, 7,676 partial-alpha, and 12,769 opaque pixels.

This run does not prove that another small mark will remain legible at 16 px.

The ICO directory and embedded PNG dimensions were read from the downloaded files; alpha counts were computed from decoded pixels. The fixtures were generated locally for these runs, so the measurements describe these inputs only.

Size guide

What do ICO sizes mean?

Each selected number is a square pixel layer stored in the same ICO file. A file containing several layers gives Windows and other icon-aware software a matching resolution to use at different display sizes.

FAQ

PNG to ICO questions

How do I convert a PNG file to an icon?

Choose one PNG, select the ICO size layers, and download the generated .ico file. The conversion runs locally in this browser.

Can I change PNG to ICO without uploading it?

Yes. The file is read by your browser and is not sent to a server.

Does the ICO file keep a transparent background?

Yes. The converter draws each layer on a transparent canvas and stores PNG image data inside the ICO file.

What is the difference between PNG to ICO and convert PNG to ICO format?

They describe the same conversion: turning a PNG image into an ICO icon file with one or more pixel layers.

Can I use this as a PNG to icon converter?

Yes. Choose a PNG, select the icon size layers, and download one ICO file created locally in your browser.
