Frequently Asked Questions
How do I check the DPI of my image?
Simply upload your image using the tool above. It reads the embedded EXIF metadata directly in your browser and instantly displays the horizontal and vertical DPI (Dots Per Inch) resolution of the file.
What is a good DPI for printing?
For high-quality professional printing, 300 DPI is the standard requirement. This ensures sharp, crisp details without pixelation. For large format prints viewed from a distance (like banners), 150 DPI is often acceptable.
What is the difference between DPI and PPI?
DPI stands for Dots Per Inch (used for physical printing dots), while PPI stands for Pixels Per Inch (used for digital screens). In the context of digital image files, the terms are often used interchangeably to refer to the image's embedded resolution setting.
Why does my image say 72 DPI?
72 DPI (and 96 DPI) are legacy standard resolutions for web images. Many digital cameras, smartphones, and web editing tools save images at 72 DPI by default to optimize for screen viewing.
Does changing the DPI change the file size?
Changing the DPI value in metadata alone does not change the file size or the total number of pixels in the image; it only tells a printer how densely to print those pixels. However, 'resampling' an image to a higher DPI will increase pixel dimensions and file size.
Is my image uploaded to a server?
No. This tool runs 100% locally in your web browser. The EXIF metadata is parsed instantly on your device, ensuring complete privacy.
