FAQs about Changing DPI of Images

What is DPI?

+

DPI (dots per inch) defines the number of ink dots a printer deposits per inch, directly impacting print sharpness and detail. Higher DPI means more dots per inch, which can make pictures clearer, sharper, but larger file size. While lower DPI can decrease file size and loading time, better for web pages; but it will also lower quality when enlarged for a widescreen or printed at a larger size. Therefore, change the image DPI to a suitable one according to different uses.

How to choose the right DPI?

+

Match the DPI to your purpose with Poindeo's predefined DPIs:

  • 300 DPI is commonly used for standard printing.
  • 150 or 200 DPI is used for smaller prints like posters/flyers.

Resolution describes digital image quality on any screen display. For example, using high-resolution and a standard 300 DPI ensures printing quality; Prioritize image resolution over DPI when sharing photos on social media, emails, etc.
