What 300 DPI actually means
DPI (dots per inch) is a printing instruction stored in the file. It doesn't change how the image looks on screen — it tells a printer how large to print each pixel. 300 DPI is the standard for crisp printing and is required by many application forms and publishers.
This tool changes only that tag. It doesn't re-compress or resize your image, so quality is exactly preserved. If a form says "photo must be 300 DPI", this makes the file report 300 DPI.
How to convert an image to 300 DPI
Add your image and the tool sets the DPI metadata to 300 instantly. By default your pixels stay identical — only the print-resolution tag changes. Download and you're done.
If you specifically need the printed size to stay the same after changing DPI, tick "resize pixels to keep the same print size" — most people don't need this.
