What is DPI and Why Does It Matter?
DPI stands for Dots Per Inch — it defines how many dots of ink a printer places per inch of paper. Higher DPI means sharper, more detailed prints. For screen display, 72–96 DPI is standard. For professional printing and government documents, 300 DPI is the industry standard.

Frequently Asked Questions
Does changing DPI affect image quality?
No. Changing DPI metadata does not resize or affect pixel data — it only changes how software interprets the print size. Pixel dimensions stay the same.
What DPI does USCIS require?
USCIS and US State Department recommend 300 DPI for printed photos. For digital uploads (DS-160, DV Lottery online), DPI is less critical — file size (max 240KB) and pixel dimensions (600–1200px) matter more.
Why is my photo 72 DPI?
Most smartphone and digital cameras save photos at 72 DPI by default. This is fine for screens but may need changing to 300 DPI for printing or government document submission.
Does this tool resize my image?
No. This tool only changes the DPI metadata in the JPEG header. Your image pixel dimensions stay exactly the same.
Is my image uploaded to a server?
No. All processing happens in your browser using JavaScript. Your image never leaves your device.
