This free Photo Print Size Tool helps users convert any photo to precise print dimensions without installing software. The interface provides one‑click presets for common formats such as stamp photos, passport photos, ID cards, and postcards, as well as a flexible custom size mode where width and height can be entered manually. Sizes are defined in millimeters by default, with automatic conversion to centimeters and inches for users who work with different measurement systems.

A dedicated DPI selector lets users choose between 150, 200, 300, and 600 DPI, and the tool instantly calculates the equivalent pixel resolution, displaying it directly under the controls. The preview canvas shows how the chosen print size will look, using aspect‑ratio‑preserving cropping so the image fills the frame without distortion, similar to cover‑style resizing used in professional print size calculators. This makes it easy to see whether the subject is correctly centered and whether the resolution is sufficient before downloading.

The background section includes presets like white, light gray, blue, red, and a fully customizable color picker, which is especially useful for passport and ID photos that must follow specific background rules. Users can download the final image as a PNG, retaining transparency when needed, or as a JPEG optimized for typical photo lab workflows at the chosen DPI. All processing runs in the browser for privacy, making this tool ideal for preparing photos for documents, online applications, print orders, and quick at‑home printing.
