Frequently asked questions
Are my files uploaded to a server?
No. Everything is processed entirely inside your browser. Your files never leave your device or get sent anywhere.
What is DPI?
DPI (dots per inch) tells a printer how large to render each pixel. 300 DPI is standard for sharp photo prints; 72 DPI is typical for screens.
Does changing DPI change the pixels?
Only if you enter a print size. Leave width and height blank to keep the same pixels and just tag the DPI; enter a print size to resize to exactly that size at your DPI.
