FAQs about Changing DPI of Images
What is DPI?
DPI is abbreviated from dots per inch, which means the number of ink dots a printer deposits per inch. DPI works when images need to be read by some devices like printers. Changing DPI of images directly impacts print sharpness and detail.
Higher DPI means more dots per inch, which can make pictures clearer and sharper. While lower DPI can decrease file loading time, better for web pages; but it will also lower quality when enlarged for a widescreen or printed at a larger size.
How to increase the DPI of an image?
You can increase the image DPI using image editors like Photoshop, but our online DPI converter enables you to increase the DPI simply — upload your image, select a DPI value, and download it. For example, to increase the 96 DPI of an image, choose the file and set the popular 300 DPI, click the download button to save it.
How to choose the right DPI?
Match the specific DPI to different purposes. Here are some main DPI uses:
- 300 DPI is commonly used for standard printing.
- 150 or 200 DPI is used for smaller prints like posters/flyers.
- 600 or higher DPI is used for higher quality printing, like larger images or longer viewing distance (exhibition-quality artwork).
This DPI converter supports you in selecting all the above DPI values as a preset or setting a custom one.

Is DPI the same as image resolution?
DPI is the density of printed dots per inch, written as 300 DPI; Resolution, also PPI (pixels per inch), is the number of pixels, like 1920 * 1080 pixels. DPI especially refers to print quality. Resolution describes digital image quality on any screen display. For example, using high-resolution and a standard 300 DPI ensures printing quality; Prioritize image resolution over DPI when sharing photos on social media, emails, etc.
How to check the DPI of an image?
Here are the steps to check the original DPI on your computer: Right-click the image > Select Properties (Windows) or Get Info (Mac) > Find the Details tab > Scroll down to view DPI. While there is no direct way to check the DPI on mobile, you can only view the resolution via the Photos/Images app.
