Image DPI/PPI Changer for Printing

Change the DPI (Dots Per Inch) metadata of your images to 300 DPI. Ensure your photos are accepted by professional printing companies and publishers.

Pass Printing Requirements

When you submit artwork to a magazine or a print-on-demand service (like Redbubble), they often reject your file with the error: 'Image must be 300 DPI.' Web images default to 72 DPI. This tool alters the EXIF metadata of your image file, forcefully rewriting the header to 300 DPI without altering the actual pixel data, ensuring it passes the printer's automated checks.

Why Use Our Image DPI/PPI Changer?

  • Print Ready: Instantly satisfy strict 300 DPI commercial print rules.
  • Metadata Only: Does not unnecessarily re-compress or destroy your pixels.
  • Supports All Formats: Works on standard JPGs and high-quality PNGs.
  • Offline Instant: Metadata is rewritten in milliseconds.

How to Use the Image DPI/PPI Changer

1.

Upload the image that was rejected by your printer.

2.

Select your Target DPI (usually 300).

3.

Click 'Change DPI'.

4.

Download the updated file and resubmit it.

Frequently Asked Questions

Does changing the DPI make the image look better?

No! DPI is just a piece of text (metadata) telling the physical printer how tightly to pack the ink dots. It does not magically add resolution or pixels to a low-quality image.

My image is 800x600 pixels. Can I print it at 300 DPI?

Yes, but the physical print will be very small (about 2.6 x 2 inches). To print a large poster at 300 DPI, you need a massive amount of pixels (e.g., 6000x4000).
