Optimize · Browser-first processing
Set a target DPI for print-oriented software while retaining the original width and height in pixels.
Select a supported file or enter the requested values, then run the tool.
This browser tool does not upload the selected source to ImgNimble. Closing or refreshing clears the selected files and generated result from the page.
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.
DPI Metadata Changer validates the selected file before processing. Use JPG, JPEG, PNG, WEBP, GIF, HEIC, HEIF, SVG within the 40 MB per-file limit. Keep an untouched original for comparison.
The DPI Metadata Changer workflow runs in browser memory. ImgNimble does not receive the source file for this local operation; refreshing or closing the page clears the selected input and generated in-page result.
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.
