When printing digital photos, PDI (dots per inch) is a very important parameter. It is used to compare digital image size (pixels) and the resulting printed version. The higher is DPI value, the more pixels will be placed on the square inch of the printed image and the smaller this image will be. For example, an image with resolution of 6000×3000 pixels printed with 600 DPI will have size of 10×5 inches. Image Converter Plus will help you prepare a batch of images for printing.
Here is a sample conversion of a batch of images with changing DPI to 300.
- Launch Image Converter Plus. Go to “Photos” tab, select and add large images you want to process.
- Go to Profiles tab. In “Operation before save: Add operation” line, click “Add operation” and select “Resize” from the menu.
- Click “+” mark located to the left from “Add operation” line to open the group of settings for added operations.
- In “Resize”, set the value of “Horizontal resolution” to the size you need (in our case, 300 pixels/inch). “Use as horizontal” checkbox connects horizontal and vertical resolution and should be enabled in most cases.
- In “Save images in …. format”, select the needed format (for example, JPEG).
- Specify settings for the output format (optimal values are specified by default).
- Specify the folder to save converted images to.
- Specify other settings.
- Press “Start” button to start conversion.
