What Is DPI and Why Does It Matter?

DPI (dots per inch) defines the print resolution of an image. A higher DPI means better print quality. While images displayed on screens typically use 72 DPI, professional printing often requires 300 DPI or higher. Our free DPI changer lets you increase or decrease DPI online without needing Photoshop or any software installation.

How to Change Image DPI Online for Free?

  1. Upload your image (JPEG, PNG, or WebP).
  2. Select a DPI preset like 300 or 600, or enter a custom DPI.
  3. Click “Convert to DPI” and download your new image.

This DPI conversion is done 100% client-side in your browser. Your images never leave your device — it's safe, fast, and free.

When Should You Change DPI?

  • For printing: Convert 72 DPI to 300 DPI for better quality prints.
  • For scanning: Adjust scanned images to 600 DPI for archiving.
  • For design: Ensure DPI consistency across images in graphic design workflows.

Supported Formats

Our tool works with JPEG, JPG, PNG, and WebP files. Other formats may be added soon. The DPI metadata is embedded directly into your image file so it’s recognized by printers and PDF generators.

Is This Like Resizing?

No. Changing DPI does not resize or compress the image — it simply tells printers how densely to print the existing pixels. If you want to reduce image file size, use our Image Compressor tool.
