Common questions
DPI Metadata Changer reads the selected input into browser memory and performs its documented operation on this device. It does not submit the source file to ImgNimble while using this browser-first workspace.
A JPEG with updated JFIF density or a PNG with an updated pHYs metadata chunk.
DPI metadata does not add detail. Physical print size changes only in software that reads the density field, and uncommon files may need a specialist editor.
Practical checks
Set a target DPI for print-oriented software while retaining the original width and height in pixels.
Keep the source, download the DPI Metadata Changer result as a new file, and verify dimensions, transparency, colour, metadata and visual detail before replacing any production asset.

Resize images to exact pixels or a percentage while optionally preserving the original aspect ratio.
Align and size a portrait using adjustable visual guides and common document-photo canvas presets.
