DPI is commonly used to describe how densely image pixels should be placed on paper. It is not the same as pixel dimensions: changing a DPI tag alone does not create more image detail.
Step-by-step instructions
- Check the pixel width and height of the image.
- Work out the intended physical print size and required pixel density.
- Use the CODAC DPI changer to update JPEG or PNG resolution metadata when that is what your workflow needs.
- Confirm the result in the target application or print workflow.
Helpful tips
- A 300 DPI setting cannot turn a small image into a high-detail photograph.
- Pixel dimensions and intended print size together determine print density.
- Some apps ignore or reinterpret DPI metadata; verify in the application that will print the image.
