About Check Image DPI
Find out the DPI stored in any picture and what it means in practice: how many pixels it has, how many megapixels, and exactly how big it will print at 300 DPI (photo quality), 150 DPI, 96 or 72.
Add many pictures to compare them side by side and export everything as a CSV table. Need a different DPI? The DPI Converter changes it without touching the pixels.
Good for
- Checking photos before sending them to a printer
- Meeting DPI rules on application forms
- Finding the largest sharp print size of a picture
Tip: For printing, look at the size at 300 DPI — that is the largest print that will look sharp up close.
Frequently asked questions
What is DPI?
Dots per inch — how many pixels go into each inch when the picture is printed. The same picture prints larger at a low DPI and smaller but sharper at a high DPI.
What DPI do I need for printing?
300 DPI for photo-quality prints, 150 DPI for posters and documents seen from a distance. The table shows the largest sharp print each picture can give.
Why does my picture say 72 or 96 DPI?
Many cameras, phones and screenshot tools store 72 or 96 by default. The number doesn’t change the pixels — use the DPI Converter to set 300 for printing.
Does DPI matter for websites?
No. Screens show pictures by their pixels; DPI only matters when printing or for forms that ask for a specific value.
Are my pictures uploaded?
No. The files are read in your browser and nothing is uploaded.
