Set the exact size a form asks for, in pixels, cm, mm or inches, choose the DPI, and keep the file between a minimum and maximum KB. The DPI is written into the file. Your photo never leaves your browser.
Enter all three. JPG output is tuned to fit the KB range at the exact pixel size.
This works, but the KB-only tool also shrinks pixels when needed to reach very small sizes.

This tool resizes only. Use the passport photo maker for backgrounds and face framing.

Some upload checks read the DPI stored in the file. This tool writes it.
DPI (dots per inch) says how many pixels make up one printed inch. So pixels = inches x DPI. A 3.5 x 4.5 cm photo at 300 DPI is 413 x 531 pixels; at 200 DPI it is 276 x 354 pixels. When a form gives the size in cm and a DPI, this tool works out the pixels for you.
DPI is a label that tells printers how big to print the pixels. Raising it without adding pixels makes the print smaller, not sharper. To make a small photo print large and sharp you need a higher-resolution original.
