Image and QR tools
Resize an image, check its physical print dimensions or make a static QR code for a link or text.
A smaller file and a smaller print answer different questions. The resizer changes pixel dimensions and compression for a downloadable file. The print calculator leaves the file alone and shows how its existing pixels relate to a physical size at your chosen PPI. Changing a resolution label cannot restore missing detail.
For a QR code, preserve the white border and test a scan with the final size and material. The code stores your input directly, so there is no JKook tracking link to keep active. A linked website can still move or become unavailable. These tools do not establish permission to reuse an image or brand; check the source’s terms before publishing.
