# DPI

Dots per inch: a figure stored in an image file that says how densely its pixels would be printed. On a screen it changes nothing.

Also called **dots per inch** · **PPI** · **pixels per inch**

A digital image is a grid of pixels. The dpi value does not add or remove any of them; it only tells a printer how many pixels to place along each inch of paper. The same file tagged with a low or a high value shows exactly the same picture on a product page, because a screen displays pixels one for one.

Some marketplace specifications still name a dpi value beside the pixel size, a habit carried over from print catalogues. Where both are given, the pixel dimensions are what decides sharpness and zoom, and the dpi value is a field in the file that an image editor can set without changing the picture.

Raising the dpi value does not make a small image larger or sharper. An image with too few pixels needs more pixels, either from a larger original or from upscaling, and an image with enough pixels passes whatever its dpi field says, as long as the marketplace does not check that field.

## DPI, answered.

**Does DPI matter for product photos online?**

No. A screen shows an image pixel for pixel, so the dpi value stored in the file has no effect on how sharp or how large the picture looks on a product page. What counts online is the number of pixels in width and height. The value matters only when the image is printed, or when a marketplace's upload check reads that field.

**How do I change the DPI of an image without losing quality?**

Change the value in an image editor with resampling switched off. The editor then rewrites only the dpi field and leaves every pixel as it was, so nothing is lost. With resampling switched on, the same setting adds or removes pixels to match the new value, which alters the picture and its dimensions.

## What marketplaces say about it.
