Image DPI Viewer

Quickly check the DPI (dots per inch) metadata stored inside an image file's header. Important for print, scanning, and pre-press workflows.

What it reads

  • PNG: parses the pHYs chunk and converts pixels-per-meter to DPI
  • JPEG: parses the JFIF APP0 segment density fields (DPI or DPCM)

Notes

  • Many images have no DPI metadata; in that case the browser defaults to 96 DPI on screen.
  • EXIF resolution fields are not parsed here — JFIF takes priority.

Use cases

  • Verify print-ready resolution
  • Diagnose print sizing issues
  • Pre-press quality checks
  • Photo scanning workflow validation
