The Best Image DPI & PPI Checker Online

When sending files to a professional printing service, ensuring your images have the correct DPI (Dots Per Inch) or PPI (Pixels Per Inch) is critical. Most high-quality print jobs require a minimum of 300 DPI to avoid looking pixelated or blurry.

Our Free Online Image DPI Checker uses advanced local browser scripts to scan the deep EXIF, JFIF, and pHYs metadata headers inside your JPG, PNG, and TIFF files. It instantly reveals the exact embedded resolution settings without requiring you to download heavy photo editing software like Photoshop.

Why Use Our DPI Analyzer?

Deep Metadata Scanning

We don't just guess based on file size. Our tool reads binary JFIF segments in JPEGs, EXIF resolution tags, and physical pixel dimensions (pHYs) inside PNG files.

100% Client-Side Privacy

Your private photos and confidential client artworks are never uploaded. The parsing happens directly in your browser's local memory instantly.

Batch Processing & CSV Export

Need to verify a folder of 100 images for a magazine print? Drag them all in and instantly export a CSV report detailing the DPI of every single file.

Lightning Fast Performance

Because we parse the binary headers directly via JavaScript ArrayBuffers, checking the DPI of massive 50MB print files takes less than a second.

Frequently Asked Questions

What is the difference between DPI and PPI?
PPI (Pixels Per Inch) refers to digital screens and the actual number of pixels in your digital image file. DPI (Dots Per Inch) is a physical printing term referring to the ink drops a printer puts on paper. However, in modern digital software and everyday conversation, the two terms are used completely interchangeably to refer to the image's embedded print-resolution density.
Why does my image say "Not Set / 72 DPI (Web Default)"?
If an image is created specifically for digital use (like a screenshot, or an image saved for web), graphic software typically strips out the DPI metadata to save file size. Without embedded metadata, standard operating systems and software assume a default legacy screen resolution of 72 DPI (or sometimes 96 DPI).
Can I use this tool to change my image to 300 DPI?
No, this tool strictly reads and checks the existing DPI. To actually change or overwrite the DPI of an image to 300 DPI for printing, you will need to use an Image DPI Converter tool or software like Adobe Photoshop.
