Step-by-Step
- Upload your image.
- Enter the target DPI value — commonly 300 for print submission requirements.
- Convert and download the result.
What Actually Changes
This process rewrites a specific metadata field inside the image file — the DPI (or PPI) tag — without touching the actual pixel grid. The file's width and height in pixels stay exactly the same before and after; only the recorded "intended print density" number changes.
What Doesn't Change
The image looks identical on screen before and after, since screens and browsers render based on pixel dimensions, not the DPI tag. File size typically stays about the same too, since no image data was added or removed — just a small metadata value.
Verify It Worked
Check the image's properties (right-click → Properties on Windows, or Get Info on Mac) after converting to confirm the DPI value shows the number you set. If a specific submission system rejected your file for DPI, re-uploading the converted version with the correct tag should satisfy that specific check.
