Pixel dimensions and physical dimensions work together: the same image can be sharp at one size and soft at another.
Use the fit setting to make crop and border trade-offs visible, then copy the production pixel size for your printer or designer.
Frequently asked questions
What PPI should I use for printing?
300 PPI is a common target for detailed photographic prints. Larger viewing distances can tolerate less.
Does this upload my image?
No. The browser reads image dimensions locally; the image is not sent to a server.
What is bleed?
Bleed is extra image area beyond the finished edge, allowing a print to be trimmed cleanly.
