About this conversion
JPEG is the most widely supported photo format — every browser, app, and device can open it, at the cost of some compression visible at low quality settings. ICO keeps every pixel exactly, so the conversion itself adds no further change.
Common questions
Are my files uploaded to a server?
No. The conversion runs entirely in your browser. Your files never leave your device.
Will converting to ICO reduce quality?
No. ICO keeps every pixel exactly as it was — there is no quality loss from the conversion itself. Any quality reduction that already existed in the JPEG source will remain, but the conversion adds nothing further.
Does ICO support transparent backgrounds?
Yes — ICO supports transparency — but JPEG does not, so there is no transparent data to carry over. The output will have a solid background.
