## What is Image DPI Changer?

Change the DPI metadata of your photos for print-ready files.

This app does not resize your images. It updates only the DPI metadata stored in JPEG, PNG, and HEIC files. It is not an image upscaler or enhancer.

WHO IT'S FOR

• Print submissions that require 300 DPI
• Research papers and reports with image requirements
• Checking print size before photo printing

HOW IT WORKS

1. Choose a photo or image file
2. Select the target DPI (such as 300)
3. Convert, then save or share

FEATURES

• Presets: 72, 96, 150, 300, 350, and 600 DPI
• Custom DPI input
• JPEG, PNG, and HEIC support
• Before/after DPI and print size preview (cm / inch)
• Pixel dimensions stay unchanged
• Batch conversion for multiple images
• Save to Photos, export files, and share

PRIVACY

Image processing runs on your iPhone. Your photos are not uploaded to a server for DPI conversion.

This app uses Google AdMob for ads.

No account is required.
