Change Image DPI Without Compromise
Changing an image's DPI means you are editing a piece of metadata (information about the image) that tells a printer how densely to place the pixels on a physical page. It does not change the actual pixel dimensions of the image itself.
It's a measurement of print resolution. It specifies how many individual dots of ink a printer will place within one linear inch of paper.

Frequently Asked Questions
Find quick answers to common questions about our Converter.
What is DPI?
DPI (Dots Per Inch) is a measurement of printing resolution. It refers to the number of individual dots of ink a printer can place within a one-inch line. In a digital context, it's often (and sometimes incorrectly) used interchangeably with PPI (Pixels Per Inch), which defines the pixel density of a digital image on a screen.
What image formats does your compressor support?
Our tool supports all major image formats including JPG, PNG, GIF, and WebP. We use format-specific optimization algorithms to ensure the best results for each file type while maintaining quality.
Will increasing the DPI make my low-resolution image look better for printing?
No. This is the most critical point to understand. If you have a small, low-resolution image (e.g., 500x500px) and you change its DPI from 72 to 300 without resampling, you are just telling the printer to print those 500 pixels in a very small space (~1.6 inches). If you enable resampling to make it print at a larger size, the software will invent new pixels (interpolation), resulting in a blurry, blocky, and low-quality print. You cannot create detail that was never there.
What does a DPI converter actually do?
When you use a simple DPI converter, it primarily changes a number in the image's header information. It does not add new detail or information to the image.
How do you ensure my images remain private?
All processing occurs in your browser - we never upload your images to our servers. Your files stay entirely on your device during compression. We use Web Workers for secure, sandboxed processing that can't access other files or data on your computer.
