Frequently Asked Questions
Does uploading an image compress or resize my file?
No. The file is inspected entirely within your local browser memory using client-side JavaScript without altering or transferring your file.
Why does my image show different print sizes at different DPIs?
Because DPI defines dot density. At 300 DPI, each inch requires 300 pixels (smaller, sharper print). At 150 DPI, each inch requires only 150 pixels (doubles the physical width and height but with lower dot density).
