Understanding DPI for High-Resolution Printing
DPI (Dots Per Inch) controls how dense image detail appears on paper. Pixel count alone does not guarantee good print output. DPI decides how those pixels map onto physical size.
Choosing 500, 600, or 1000 DPI
500 DPI is commonly used for fingerprint workflows, 600 DPI is a strong default for high-quality print, and 1000 DPI is useful for forensic-level detail.

Frequently Asked Questions
Does this tool upscale my image?
No. It uses your original pixels and changes print density/physical size according to DPI.
Can I upload PDF files directly?
Not in this version. It currently accepts JPG and PNG and exports DPI-controlled PDFs.
