Change an image to 300 DPI
Print shops, publishers and photo-contest systems reject anything not at 300 DPI. Your image is fine pixel-wise — only the metadata says 72. Fix the number, not the image.

Frequently asked questions
Will changing DPI improve print quality?
No — DPI metadata describes how densely pixels are printed, not how many you have. If your image lacks pixels for the print size, you need a higher-resolution source. This tool fixes the metadata declaration.
How do I verify the result?
Photoshop: Image → Image Size (uncheck Resample) shows the DPI. On macOS, Get Info; on Linux, `identify -format "%x x %y"`. Our pipeline itself verifies the written DPI before delivering.
Which formats are supported?
JPG, PNG, WebP in; JPG/PNG/WebP/TIFF out. TIFF is recommended for professional print workflows.
When this tool is not the right choice
Your image genuinely lacks pixels for the target print size.
Reshoot or find a higher-resolution source — no metadata change can add real detail.

You need the image resized for screens (web, email).
