Most official documents require photos at 300 DPI (dots per inch) for print quality. For digital submissions, the pixel dimensions matter more than DPI — for example, US passport photos need at least 600x600 pixels. Last Min ID Photo generates all photos at 300 DPI or higher.
Technically yes, but resizing can reduce quality and may not meet official requirements. Cropping incorrectly can also lead to rejection if head size ratios are wrong. Last Min ID Photo automatically generates photos at the exact size you need with proper proportions.
