About the Photo DPI Converter
The Photo DPI Converter is built to modify the print resolution metadata of your photos and scanned documents. Portals like Kerala PSC (Thulasi) and various passport application frameworks demand photographs scanned at exactly 150 DPI, 200 DPI, or 300 DPI.
Changing the DPI (Dots Per Inch) updates the EXIF header segment of the image without resizing pixel coordinates or cropping your face. All metadata injections occur locally in your browser, maintaining full image privacy.

Troubleshooting & Helpful Tips
DPI check shows original value: Windows File Explorer sometimes cache metadata. To verify the DPI change, use our Image Upload Validator or right-click the file, go to Properties > Details, and check horizontal/vertical resolution.
Pixel dimensions changed: Changing the DPI alone will not modify pixel counts. If you need to change pixel bounds, use our main Photo Resizer first.

Frequently Asked Questions
Does changing DPI change the image pixels?
No, changing DPI only changes the metadata instructions that tell a printer how dense to print the dots. Pixel dimensions remain identical.
Why does Kerala PSC require 150 DPI?
It ensures that if the ID card is printed physically, the resolution is high enough to look clear. Low DPI uploads cause pixelated print ID badges.
How can I verify the DPI of my downloaded image?
Right-click the image on Windows, choose Properties, click the Details tab, and inspect the Horizontal/Vertical Resolution fields.
