Frequently Asked Questions
Is my image uploaded to a server?
No. Everything happens securely inside your own web browser using HTML5 technology. Your image never leaves your computer, ensuring complete privacy.
What does "Overlap" mean?
Overlap adds a small duplicate strip at the edges of adjacent pages. This makes it much easier to align and glue or tape the sheets together without leaving white gaps. A 5 mm overlap is highly recommended.
How should I print the generated PDF?
When printing from Adobe Reader or your browser, make sure the scaling is set to "100%" or "Actual Size". Do NOT use the "Fit to Page" option, as it will shrink the margins and ruin the overlap alignment.
