Frequently Asked Questions (FAQ)
What is the difference between DPI and Pixel Resolution?
DPI (Dots Per Inch) is density information that determines how many pixels are placed in one inch when printing an image. Pixel Resolution (Width/Height) is the total number of pixels the image file contains. DPI affects print quality, while pixel resolution affects the detail of the image.
Can changing DPI improve the quality of a low-resolution image?
Changing the DPI does not create or modify the pixel data itself. It only modifies the metadata that tells the printer how to process the image. While it won't drastically improve the quality of low-resolution images, it ensures the correct physical size and density for optimal printing.
Does changing the image size (pixels) reduce quality?
Yes, enlarging an image (e.g., 1000px → 2000px) can make it look blurry. Reducing the size (e.g., 2000px → 1000px) decreases file size with minimal visual quality loss. The resolution change on this site uses the browser's canvas function.
