    How much smaller will the file be?

    Both formats keep every pixel, so the size depends entirely on the picture. Flat colour and hard edges compress well in either. A photograph is large in both, and neither is the right format for one.

    Can I convert it back afterwards?

    Yes. Neither format throws anything away, so the round trip returns the same picture, pixel for pixel.

    About ICO

    The Windows icon format, usually holding several small sizes in one file.

    About PNG

    Lossless and keeps transparency, at the cost of much larger photographs.

    Will the quality change?

    PNG is lossless, so nothing is thrown away in the encoding. If the ICO was itself lossy, its existing artefacts are preserved faithfully. Converting cannot recover detail that was already discarded, and the file will usually get considerably larger.

    Other conversions

    ICO also converts to JPG, WebP, AVIF, PDF and Word.

    PNG also comes from HEIC, JPG, WebP, AVIF and GIF.
