    The details

    What happens when you convert between document formats

    The Windows icon container. It holds several sizes of the same image in one file. The document is opened in a layout engine and re-saved in the target format, mapping each style onto the closest equivalent in the new format. The result is a the default photo format. every camera, every phone and every printer speaks it, produced entirely inside your browser.

    What survives

    • The text and the paragraph structure
    • Most formatting: fonts, sizes, colours, alignment, lists and tables
    • Embedded images

    What changes

    • Styles that have no equivalent are approximated
    • The file may gain or lose features the target format does not support

    Where it goes wrong

    • Styles are usually mapped by name, so renaming a style before converting can lose the mapping
    • The target format may not support the same page size or margins

    Why anyone would do this

    Different teams use different formats, and the content should not be held hostage by that.

    About the format

    The Windows icon container.

    A header, a directory of image entries and the image data itself. Modern ICO files can embed PNG data for the larger sizes.

    Where it is good
    • One file for every size Windows needs
    • Accepted by browsers for favicons
    • Can hold several different images at once
    Where it falls short
    • Very few other programs write ICO files
    • Windows only — macOS and Linux ignore it
    • A 256-pixel icon in PNG form is still a large file
    You will find it on
    Windows, web browsers, software installers

    The thing people miss

    A modern ICO can contain PNG images inside it, which is why a 16×16 icon and a 256×256 one can live in the same file.

    About the target

    The default photo format.

    A lossy, block-based compression called JPEG. The file is a grid of small blocks, each one stored slightly differently from the last, and the decoder guesses the missing detail when it opens.

    • Universally supported — it opens everywhere, on every device, in every browser
    • Very small files for the quality it delivers
    • Camera phones, scanners and social platforms all default to it

    Questions

    ICO conversion questions

    What actually happens to my ICO file when I convert it to JPG?

    The document is opened in a layout engine and re-saved in the target format, mapping each style onto the closest equivalent in the new format. So the ICO file is unpacked, the content is laid out, and the result is written out as JPG. The text and the paragraph structure survives unchanged.

    Will converting ICO to JPG reduce the quality?

    Partly. Styles that have no equivalent are approximated The text itself is never re-typed, so no words are lost.

    Is my ICO file uploaded to a server?

    No. This ICO to JPG conversion runs as JavaScript inside your browser tab. The file is read from your device and the result is written back to your device, so there is no upload step, no file-size limit and no copy of your ICO file on any server.

    Do I need an account or will there be a watermark?

    Neither. There is no sign-up step, no email capture and no watermark on the output. The only limits are the ones your own device imposes.

    What is the most common mistake people make when converting ICO to JPG?

    Styles are usually mapped by name, so renaming a style before converting can lose the mapping

    Why would somebody convert ICO to JPG at all?

    Different teams use different formats, and the content should not be held hostage by that. In short: making a proper favicon for a website

    Something most people do not know about ICO?

    A modern ICO can contain PNG images inside it, which is why a 16×16 icon and a 256×256 one can live in the same file.
