Will the icon have a transparent background?

Only in the padding. JPG images carry no alpha channel, so the artwork itself stays opaque — and if it is not square, the space added to square it off is transparent. For an icon with a fully transparent background, start from a PNG version of the graphic instead.

Does converting JPG to ICO improve image quality?

No — detail the original JPG compression discarded is gone for good, and no format change can restore it. What ICO guarantees is that nothing further is lost: the decoded image is stored exactly, so it will survive repeated edits and saves untouched.

What sizes are included in the ICO file?

FileMorf embeds the standard icon sizes — 16, 32, 48, 64, 128, and 256 pixels — up to your source image's own size, each stored as a PNG inside the .ico container. Browsers and Windows then pick the crispest match for wherever the icon appears: browser tabs, bookmarks, taskbars, or desktop shortcuts. Start from a source of 256px or larger to get the full set.

Will the .ico file work as a favicon everywhere?

Yes. FileMorf writes PNG-compressed ICO, the modern variant supported by every current browser and by Windows since Vista. Drop it in your site root as favicon.ico or reference it with a tag.

What if my image isn't square?

Icons are square by definition, so non-square images are scaled to fit and centered on a transparent square canvas — nothing is cropped or stretched. For the cleanest favicon, start from a roughly square logo or mark.

Questions about JPG and ICO.

Check the format behavior, limitations, and follow-up options before processing a real file.

When the only copy of a logo or mark is a JPG, converting it to .ico gets you a working favicon or Windows icon in one step — FileMorf renders the standard icon sizes and packs them into a single file. Because JPG has no transparency, the icon will be opaque; if you have a PNG version with a transparent background, converting that instead produces a cleaner result.
