DPI describes how many pixels cover each inch of a print. The same photo can be a small sharp print at 300 DPI or a large softer poster at 100 DPI.
Changing DPI alone updates that density declaration. Resampling changes the pixel grid so a chosen physical size hits your target DPI.

Questions
DPI (dots per inch) / PPI (pixels per inch) describes how pixel density maps to physical print size. Higher DPI usually means a smaller print from the same pixel count.
In digital imaging they are often used interchangeably for pixel density. Printers speak in dots; screens and files usually mean pixels per inch.
When the pixel grid is already correct and you only need the file to declare the right print density for a layout or print software.
When you need a specific physical size at a target DPI - for example A4 at 300 DPI - which requires a defined pixel width and height.
No. Screens display pixels. DPI metadata mainly affects print size calculations and some design apps.
Input includes JPEG, PNG, WebP, AVIF, HEIC, TIFF, and BMP. Output can keep the original or write JPEG, PNG, WebP, AVIF, or TIFF.
