Image DPI Changer
Resize an image's pixel dimensions to match a target print size and DPI, for preparing photos or graphics for printing.
About this image dpi changer
Print size depends on both an image's pixel dimensions and its DPI (dots per inch). This tool calculates the pixel width you need for a specific physical print size and DPI, then resizes the image to match.
How image dpi changer works
You enter your target width in inches and your desired DPI, and the tool calculates the matching pixel dimensions, then resizes the image accordingly.

What to know before using it
Browsers do not store a DPI tag inside exported PNG files, so set the DPI explicitly in your print dialog or design software when printing, the pixel dimensions produced here are what actually determine the physical print size at that DPI.
Privacy and browser-first processing
Your image is resized entirely inside your browser tab and is never uploaded to this server.
Frequently asked questions
Will the DPI be saved inside the file?
Browsers do not embed a DPI tag in exported images, this tool instead sets the correct pixel dimensions for your target size, then you set the DPI in your print dialog or design software when printing.
