What Is a DPI Checker?
A DPI Checker is an online tool that helps you check the DPI (Dots Per Inch) of an image along with its resolution, dimensions, file size, and estimated print size. Whether you want to verify a photo for printing, publishing, passport applications, or professional design work, our free DPI Checker provides detailed image information within seconds.
This tool works with popular image formats such as JPG, JPEG, PNG, WebP, BMP, and TIFF. Simply upload your image, and the tool will analyze its pixel dimensions, available DPI metadata, and print size calculations. If the image does not contain embedded DPI information, the tool will notify you while still estimating the printable size using standard values.
How Does the DPI Checker Work?
Our free image DPI Checker analyzes your uploaded image directly in your browser. The image is never uploaded to a server, making the process fast and privacy-friendly.

JPG vs PNG DPI Information
Many users search for a PNG DPI Checker or JPG DPI Checker. While JPEG images often store DPI information inside their metadata, PNG images may not always include printable DPI values. If your image contains embedded DPI metadata, this tool will display it automatically. Otherwise, the tool estimates print size using standard calculations.
Why Is 300 DPI Important?
A resolution of 300 DPI is widely considered the industry standard for high-quality printing. Magazines, brochures, business cards, books, posters, and photographs are commonly printed at 300 DPI to ensure sharp text and detailed images. If you’re wondering whether your image meets professional printing standards, this DPI Checker helps you verify it in seconds.
Frequently Asked Questions
What is DPI?
DPI stands for Dots Per Inch. It measures how many printed dots fit into one inch of an image when printed.
What is the difference between DPI and PPI?
DPI refers to print resolution, while PPI (Pixels Per Inch) describes the pixel density of digital images displayed on screens.
How can I check image DPI?
Upload your image using our free DPI Checker. The tool reads available metadata, calculates print size, and displays image information instantly.
Can I check JPG DPI?
Yes. JPEG images commonly contain DPI metadata, which this tool attempts to detect automatically.
Can I check PNG DPI?
Yes. PNG images can be analyzed for dimensions and file information. However, many PNG files do not contain embedded DPI metadata.
Is 300 DPI good for printing?
Yes. A 300 DPI image is generally considered suitable for professional-quality printing.
Why does my image show “Metadata Not Found”?
Some images do not store DPI information. In these cases, the tool estimates print size based on standard assumptions while still displaying the image dimensions.
Does resizing an image change its DPI?
Not always. Resizing changes pixel dimensions, while DPI changes only if the image metadata or print settings are modified.
Disclaimer
This DPI Checker reads image metadata when available and calculates estimated print dimensions using standard formulas. Some image formats may not store DPI information, so results may vary depending on how the image was created or exported. This tool is intended for informational purposes and should not replace professional print verification for commercial projects.
