ICO to PNG Optimization FAQ

Will PNG actually be smaller than ICO?

Almost always when going from PNG / JPG / TIFF into WebP or AVIF: expect 25-50% smaller than JPG at the same visual quality, 60-90% smaller than PNG. Going the other way (WebP / AVIF back to PNG = PNG / JPG) typically grows the file because you are leaving a more modern codec for an older one — useful for compatibility, not size.

Does ICO to PNG preserve transparency / alpha?

Transparency survives when PNG supports alpha (PNG, WebP, AVIF, GIF, TIFF, SVG). Converting to JPG flattens the alpha channel onto white — if you need transparency on the modern web target WebP or AVIF instead of PNG.

Will the PNG version look identical to the ICO on a Retina display?

At quality 80+ on WebP / AVIF the difference is invisible to anyone but a trained eye even at 3x device pixel ratio. Photos compress slightly more visibly than line art; if your ICO is screenshots or UI mockups, push quality to 90 or use a lossless PNG.

Will EXIF camera metadata survive ICO to PNG?

Usually not. In most conversions, camera EXIF fields such as the camera model and GPS position are not carried into the PNG. There is no setting on this page to keep or remove metadata, so check the result with a metadata viewer if it matters.

Can I batch convert a folder of ICO files to PNG?

Several files in one job need a paid plan. Free use is one file per conversion, one conversion an hour. On a paid plan you can add several files to one job, then download each result on its own or all of them in one ZIP.

Are my ICO files private during PNG conversion?

Yes. Uploaded ICO files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted PNG are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.

How do I serve the PNG with an ICO fallback on my site?

Use a `<picture>` element: `<picture><source srcset="image.PNG" type="image/PNG"><img src="image.ICO" alt=""></picture>`. Browsers that understand PNG fetch the smaller file; older browsers fall back to ICO. WebP is supported in 96%+ of installed browsers, AVIF in 90%+.

Why is my PNG file unexpectedly bigger / smaller than I expected?

An ICO that is already heavily compressed (low-quality JPG) often grows when re-encoded into a lossless PNG (PNG / TIFF). A high-bitrate lossless ICO (PNG / TIFF) often shrinks 60-90% when going to a lossy modern PNG (WebP / AVIF). Image content matters too — photos compress very differently from line art and screenshots.

ICO

ICO (Icon) is a popular image file format developed by Microsoft for storing icons in Windows applications. It supports multiple resolutions and color depths, making it ideal for small graphics like icons and favicons. ICO files are commonly used to represent graphical elements on computer interfaces.
