Change Image DPI Online for Print

Print shops and some templates ask for 300 DPI. DPI Changer updates the resolution metadata on an image so exporters and printers see the value you need.

DPI is not the same as pixel count. A small 400 × 400 photo labeled 300 DPI still prints tiny. If you need more pixels, Resize first; then set DPI for print workflows that read the tag.

When to change DPI

• Prepare files for a print shop that requires 300 DPI
• Match a design template that expects 72 or 150 DPI tags
• Align exports between web (often 72) and print (often 300)
• Fix a scan whose DPI tag is missing or wrong

Step-by-step

1. Open DPI Changer.
2. Load your JPG or PNG.
3. Set the target DPI (for example 300 for many print jobs).
4. Confirm pixel dimensions still meet the print size you need.
5. Download the updated file.

If the print size in inches is too small at 300 DPI, you need more pixels — resize or reshoot — not a higher DPI label alone.

FAQ

Does changing DPI add detail?

No. DPI tags tell printers how to interpret existing pixels. More detail requires more pixels or a new capture.

What DPI should I use for web?

Many web uses ignore DPI and care only about pixel size. For screen, Resize to the display width you need.

Is 300 DPI always required?

Common for photo print, not universal. Follow the shop or template spec.

Do I need an account?

No.
