About the ICO to JPG Converter
Icons often hold the best version of a logo — sometimes the only one you have. JPEG is accepted everywhere (documents, slides, upload forms), so extracting the largest size as a JPG is the quickest way to reuse it.
The largest image in the icon is decoded — PNG-compressed entries by the browser, classic BMP entries (1 to 32-bit with AND masks) by our own parser.
The JPG is written by your browser's JPEG encoder at the quality you choose; transparent areas are composited onto the fill colour first, since JPEG has no alpha channel.

Things to know
- Small icons stay small. If the largest size in the ICO is 32 px, the JPG is 32 px. Enlarging won't add detail.
- JPEG and sharp edges. Icons have hard edges; keep quality high (90%+) to avoid ringing artefacts.
