Check Image DPI
See the DPI and print size of any photo.
Your files are processed on your device and are never uploaded.
Find out the DPI of any photo in a second. Upload an image and the ShrinkBee DPI Checker shows its DPI, its size in pixels, and how big it will print in centimetres and inches – so you know whether it meets a form's "300 DPI" rule before you submit it.
How to Check Image DPI
- Choose your image – JPG or PNG.
- Read the result: the DPI stored in the file, the pixel dimensions and the print size.
- Need a different value? Click Change DPI to set it, or Check another image.
Understanding the Result
- DPI is a setting saved in the file that tells printers how many pixels to put in each inch.
- Print size = pixels ÷ DPI. A 1200 × 1800 px photo at 300 DPI prints at 4 × 6 inches.
- If no DPI is saved, most software assumes 72 or 96 DPI.
- For sharp prints you want at least 300 DPI at the size you will print – which really depends on having enough pixels.
Common Questions
My form needs 300 DPI but my photo shows 72. Use Convert DPI to set it to 300 without changing the photo.
Will changing DPI make my photo sharper? No – sharpness comes from the number of pixels. To enlarge a small photo, try Upscale Image.

Frequently Asked Questions
How do I check the DPI of an image?
Choose your image and the tool shows the DPI stored in the file, its pixel size, and how big it prints at common DPI values in inches and centimetres.
What if no DPI is shown?
Some images have no DPI saved. Most software then assumes 72 or 96 DPI. You can set a value with Convert DPI.
Is a higher DPI better?
Only for printing. Sharpness depends on the number of pixels; DPI just decides how large those pixels are printed. Screens ignore DPI.
How big will my photo print?
Print size = pixels ÷ DPI. A 1200 × 1800 pixel photo at 300 DPI prints at 4 × 6 inches.
