Change image DPI to 72
Drop an image below and download it with its density metadata set to 72 DPI. The pixel dimensions stay exactly the same — what changes is the print-density tag, which is what portals and printers actually read.

Who asks for 72 DPI?
72 DPI has been the traditional standard for web graphics since the early days of computer monitors, and browsers still treat it as the default for on-screen images. Some older content management systems and web forms explicitly ask for images at this resolution before accepting an upload. It also works well for email attachments and social media posts, where physical print size never comes into play.
What changing the DPI really does
Changing the DPI to 72 only rewrites the density metadata inside the file — the pixel dimensions stay exactly the same. Many platforms that ask for 72 DPI are really just checking that one metadata tag, not measuring anything about actual image quality.
Frequently asked questions
Does this change the resolution or quality of my image?
The width and height in pixels stay identical. The image is re-encoded at high quality during processing, and the density tag (JFIF for JPG, pHYs for PNG) is written with the value you chose.
Which formats can carry a DPI value?
JPG and PNG. WebP and AVIF have no standard density field, so choose JPG or PNG as the output when a form asks for a specific DPI.
Is my photo uploaded anywhere?
No. Everything runs locally in your browser with WebAssembly — your image never leaves your device, which makes this safe even for ID photos and documents.
