What is an Image DPI Checker?

An image DPI checker reads the metadata embedded in an image file to report its DPI (Dots Per Inch) or PPI (Pixels Per Inch) value. DPI describes how densely pixels are packed into a printed inch — higher DPI means sharper printed output.

This tool also reports pixel dimensions, megapixels, estimated print size in inches, and file size — giving you everything you need to decide if an image is ready for print or only suitable for screen use.

How to Check Image DPI Online

  1. Upload one or more images by clicking the upload area or dragging and dropping them.
  2. The tool instantly reads the DPI/PPI metadata from each image file.
  3. View the DPI, pixel dimensions, megapixels, estimated print size, and file size for each image.
  4. Use the DPI Reference Guide to understand if your image is print-ready.

If no DPI metadata is found, an amber warning is shown. This is common for PNG files and images exported for the web without DPI information embedded.

DPI vs PPI – Key Differences

DPI – Dots Per Inch

  • Refers to printer output quality.
  • How many ink dots a printer places per inch.
  • Used when describing print resolution.

PPI – Pixels Per Inch

  • Refers to digital image pixel density.
  • How many pixels fit in one inch of a digital image.
  • Used when describing screen or image resolution.

In everyday usage, DPI and PPI are used interchangeably for digital images. When you check the DPI of an image file, you are technically reading the PPI value stored in the image metadata.

When Should You Check Image DPI?

  • Before sending an image to a print shop or press.
  • When a designer or client requests "300 DPI" images.
  • Before printing business cards, brochures, banners, or posters.
  • When verifying if a downloaded image is suitable for print or only for web.
  • When checking photos from different cameras or sources for print consistency.

Is the Image DPI Checker Safe to Use?

Yes. This tool reads image metadata entirely in your browser using the JavaScript FileReader API and HTML5 Canvas. No image data is ever sent to a server — your files stay completely private on your device.

You do not need to create an account or provide any personal information. Upload your images, check the DPI, and you are done.

Frequently Asked Questions (FAQs)

What is DPI in an image?

DPI stands for Dots Per Inch. It describes how many dots or pixels are packed into one inch of a printed image. Higher DPI means sharper printed output.

What is the difference between DPI and PPI?

DPI (Dots Per Inch) refers to print output density, while PPI (Pixels Per Inch) refers to the pixel density of a digital image. They are often used interchangeably, but PPI is the correct term for digital images.

What DPI is good for printing?

300 DPI is the standard recommended resolution for high-quality print output. 72–96 DPI is standard for screen/web display. Images below 150 DPI may look blurry when printed.

Can I check DPI without uploading to a server?

Yes. This tool reads image metadata entirely in your browser using the FileReader API. No image data is sent to any server.

Why does my image show 72 DPI?

Many images saved for the web default to 72 DPI because that is the standard screen resolution. The DPI metadata does not affect how the image looks on screen — only how large it prints.

Can I check multiple images at once?

Yes. You can upload multiple images at once and this tool will display the DPI, dimensions, and file size for each one.
