Change Image DPI Online — Adjust PPI for Print Free

Print shops require 300 DPI, but your image is set to 72? The MyPDF Change DPI tool adjusts the DPI (dots per inch) metadata of your images for print, web, or specific submission requirements.

How to Change Image DPI

1. Upload your image (JPG, PNG, or TIFF).
2. Enter the target DPI value (e.g., 300 for print).
3. Download the image with updated DPI metadata.

Common DPI Settings

DPI	Use Case	Print Size (from 3000x2000 px)
72	Web/screen display	Not for print
150	Draft prints	20 x 13 inches
300	Professional print	10 x 6.7 inches
600	High-detail fine art	5 x 3.3 inches

Practical Tips

• Changing DPI alone does not add detail — it changes how many pixels map to a physical inch. A 72 DPI image set to 300 DPI has the same pixel count, just a smaller print size.
• To truly increase resolution, resize the image to more pixels first, then set the DPI.
• 300 DPI is the print standard — most professional printers require this minimum for quality output.

What is the difference between DPI and PPI?

DPI (dots per inch) technically refers to printer output. PPI (pixels per inch) refers to digital images. In practice, they are used interchangeably. This tool adjusts the PPI metadata stored in your image file.

Does changing DPI affect file size?

No. Changing DPI only modifies metadata — the pixel data remains identical. File size stays the same.
