Help improve UNQIRO
Allow anonymous usage statistics? UNQIRO would count only which tool was used, whether it finished and which links between the tools and the Format Lab were followed. Your files, text and results are never included, and this use is not counted.
What changes
Only the resolution value stored in the file (JFIF or EXIF in a JPG, pHYs in a PNG, EXIF in a WebP). The image data is copied byte for byte: no re-encoding, no quality loss, the same pixel dimensions.
Frequently asked questions
Does changing 72 DPI to 300 DPI improve quality?
No. The image keeps its pixels; it only prints smaller, about four times in each direction. For more or fewer pixels use Resize Image, for a smaller file Compress Image.
Does changing DPI remove metadata?
No. Camera details, date, GPS location and other metadata stay in the file. To remove them, use Image Metadata.
