Change image DPI to 150
Drop an image below and download it with its density metadata set to 150 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 150 DPI?
150 DPI sits comfortably between screen and professional print, delivering results that look sharp on a home inkjet or laser printer without demanding a huge source file. It is a common target for internal reports, flyers printed at home and draft proofs before sending a file to a professional printer. Many office and school printing guidelines settle on 150 DPI as the practical middle ground for everyday documents.
What changing the DPI really does
As with any DPI change, setting the value to 150 rewrites the density tag stored in the file metadata, leaving the pixel dimensions exactly as they were. The result prints at the physical size the tag specifies, but no detail is added or removed.
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.
