Set JPG or PNG DPI metadata without changing image pixel dimensions.
How to use
Choose an image, select JPG or PNG and a DPI value from 1 to 1200. Download the result and inspect its resolution metadata.
Limitations
Up to 25 MB and 24 megapixels. Changing DPI does not add detail or pixels. Images are re-encoded; JPG quality may change and original metadata may be removed. PNG pixels-per-metre rounding may cause a tiny difference in reported DPI.
