About ChangeImageDPI.com
Our Mission
At ChangeImageDPI.com, our mission is to provide a simple, free, and privacy-focused tool for changing image DPI values. We believe that everyone should have access to professional-quality image tools without compromising their privacy or paying expensive subscription fees.

⚡ Fast & Easy

🌍 Multi-Language

Why We Built This
We noticed that many online image tools require users to upload their files to remote servers, raising privacy concerns. Additionally, professional software like Photoshop can be expensive and complex for simple tasks like changing DPI.
That's why we created ChangeImageDPI.com - a tool that respects your privacy by processing everything locally in your browser, while remaining completely free and easy to use.
How It Works
Our tool uses advanced JavaScript technology to process images directly in your web browser. When you upload an image:
- The image is loaded into your browser's memory (not uploaded to any server)
- We read the current DPI metadata from the image file
- We modify the DPI value according to your selection
- The updated image is created locally on your device
- You download the modified image directly from your browser
This client-side approach ensures that your images remain completely private and secure throughout the entire process.
Supported Formats
We support all major image formats including:
- JPG/JPEG: The most common photo format
- PNG: Ideal for graphics with transparency
- WebP: Modern web-optimized format
- BMP: Uncompressed bitmap images
