This tool changes an image's DPI (dots per inch) metadata value - the setting that tells printers and some software how densely to print the image's pixels per inch. It's commonly needed when a print shop or submission portal requires a specific DPI value (like 300) before accepting a file.
Frequently asked questions
No - DPI is just metadata describing print density; changing it doesn't add or remove actual pixel detail. If your image genuinely needs more detail for print, use the Image Upscaler tool or start with a higher-resolution source.
DPI tells the printer how large to physically print each pixel - a specific DPI requirement ensures the final printed size and sharpness matches what the service expects.
Typically no - it only updates the DPI metadata field, leaving the actual pixel width and height unchanged, unless you specifically also choose to resize.
