Change image DPI to 300
Drop an image below and download it with its density metadata set to 300 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 300 DPI?
300 DPI is the long-standing industry standard for print, used by professional print shops, photo labs and publishers because it renders fine detail without visible pixelation at normal viewing distance. It is also the resolution most consulates and government portals require for passport and visa photo uploads. Magazines, brochures and photo books are typically produced at this density by default.
What changing the DPI really does
300 DPI is the most requested value precisely because so many government and visa portals check for it, yet the check is almost always limited to the metadata tag rather than the actual pixel count. Setting it correctly can be the difference between an upload being accepted or rejected, even though the pixels themselves are unchanged.
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.
