Instantly Fix "Low Resolution" Errors for Printing & Visas

Facing rejection when uploading a photo for a US Visa, passport application, or Amazon KDP book cover? The issue is often invisible: incorrect metadata. Most digital cameras and phones save images at 72 DPI (screen resolution), but high-quality printers and government portals strictly require 300 DPI. This tool instantly adjusts that metadata value without reducing your image quality, ensuring your files are accepted every time.

Why DPI Metadata Matters for Acceptance

DPI (Dots Per Inch) is a communication instruction embedded in your image header (JFIF). It tells a printer or software how tightly to pack pixels together. While changing the DPI doesn't magically add new pixels (upscaling), it is a mandatory "key" to unlock acceptance on strict portals like the US Department of State or Print-on-Demand services. Without this specific metadata tag set to 300, automated systems will reject even the highest-quality photos.

Frequently Asked Questions

Does changing DPI to 300 improve image quality?
No, changing the DPI value is a metadata change, not a resolution enhancement. It changes the scale at which the image prints, but it does not add new detail or fix a blurry photo.

Why only JPG/JPEG formats?
The specific metadata standard used for printing density (JFIF) is native to JPEG files. PNG files handle resolution differently. For the best compatibility with government forms and printers, we process JPEG headers specifically.
