Why convert PNG to ICO?

People convert PNG to ICO when they need a favicon for a website, an icon for a desktop shortcut, or a file that older Windows software expects. A direct ICO output avoids renaming tricks that produce broken files and makes the result usable by systems that require the actual icon format.

Best for

  • Create a 16px favicon for compact browser and bookmark displays.
  • Create a 32px icon for higher-density browser or Windows interface use.
  • Turn a transparent PNG logo into an icon file without changing the original artwork.

Things to keep in mind

  • You only need a normal website image
  • The source design contains tiny text that will not survive at icon size
  • You need a scalable vector icon rather than a raster icon

About PNG

PNG is a lossless raster image format that supports transparency and sharp edges. It is widely used for logos, interface graphics, screenshots, and artwork where clean detail matters.

About ICO

ICO is an icon container used mainly for website favicons and Windows icons. Icon files are displayed at small sizes, so the source artwork and chosen dimensions matter more than they do for a normal image export.

How it works

  1. 1Upload your PNG image
  2. 2Choose ICO as the output format
  3. 3Select a practical icon size such as 16px or 32px
  4. 4Convert and download the real .ico file

Quality and workflow note

The source PNG should ideally be square and remain readable at very small sizes. Converting to ICO does not add detail, so a complex logo can still look blurry when reduced. A 16px icon is useful for the smallest favicon contexts, while 32px usually gives a cleaner result on modern displays. Keep the original PNG as the master file.

Common questions
How do I convert PNG to ICO?

Upload the PNG, choose ICO, select an icon size, start the conversion, and download the resulting .ico file.

Should a favicon be 16px or 32px?

16px fits the smallest classic favicon slots, while 32px often looks cleaner on modern displays. Testing both is the safest approach.

Why does my ICO favicon look blurry?

The source may contain too much detail, may not be square, or may have been reduced to a size that is too small for the design.

Can an ICO file keep PNG transparency?

Yes, transparent source artwork can be preserved when the conversion pipeline and icon settings support it.

Can I rename a PNG file to .ico?

No. Renaming changes only the extension and usually creates an invalid or unusable icon file. A real format conversion is required.

Can an ICO file contain several icon sizes?

ICO can support multiple embedded sizes, but Converto currently creates the selected 16px or 32px output. Export both sizes separately when you want to test each one.
