The whole thing runs in your browser. Close the tab and every trace of your image is gone — there is no server that ever sees it.
Is your image high enough resolution to print?
"Resolution" mixes two things: pixel dimensions (how much detail) and DPI (how big it prints). This tool shows both, plus the physical print size at the file's current DPI, so you can tell whether an image will print sharply.
If the DPI tag isn't set, we assume 96 for the print-size estimate and flag it. To change the DPI, use the Change DPI tool.
Frequently asked questions
What DPI do I need to print?+
300 DPI is standard for sharp prints. This tool shows the current DPI and print size so you can check.
Why does it say DPI not set?+
Many images (especially screenshots and web images) have no DPI tag. Printers then assume a default. Use Change DPI to set one.
Is anything uploaded?+
No. Everything is read in your browser.
