Simply scroll up to our tool above. Upload your image, enter "300" in the input box, and click "Convert". The tool modifies the file header to specify 300 dots per inch, which tells printers to ignore the screen size and print closely packed pixels for sharpness.

Whether it's a "picture" (digital art) or a "photo" (camera shot), the process is identical. Digital cameras often save JPGs at 72 DPI metadata even if the resolution is high (e.g., 4000x6000). Using this converter ensures that print shops interpret your high-resolution file correctly instead of stretching it out.

You don't need to pay $20/month for Adobe Creative Cloud just to change one number.

how to change dpi of image?
Changing the DPI involves updating the EXIF/metadata tags (specifically the XResolution and YResolution tags) in the file header. Our tool handles this technical complexity for you automatically. Just input your desired value (usually 72, 150, or 300) and download.
Screens Ignore DPI
On a website or phone, a 1000px wide image looks exactly the same whether it is 1 DPI or 1000 DPI. Screens render pixels directly (1 image pixel = 1 screen pixel).
Printers Need DPI
Printers need to know how big to make the image on paper. 300 DPI tells the printer: "Fit 300 of these pixels into every inch of paper."
Common Requirements
Print on Demand
Printful, Redbubble, and Teespring automatically reject files under 300 DPI.
Book Publishing
Amazon KDP and IngramSpark strictly require 300 DPI for covers.
Government Forms
Some visa and passport upload portals stubbornly require 300 DPI headers.
