Alternative: Microsoft Designer
Why: Most image jobs at work are editing, not generating: resize, crop, compress, remove a background. Generation is useful for illustrations, never for real people or brands you do not own.
Privacy caveat: Do not upload ID photos or documents to generation tools; for passport-size photos and document images use an on-device tool such as ImgNimble.
