Frequently asked questions
What page sizes are available?
A4, US Letter, A3, A5, and Legal are available as target page sizes. Portrait and landscape orientations are both supported.
Will content be distorted?
No. Content is scaled proportionally — aspect ratio is preserved, so there is no stretching or distortion. Margins adjust to accommodate the new page size.
What is the difference between Scale and Crop?
Scale changes the page size and scales the content to fit. Crop changes the visible area without rescaling content — it hides edges. Use Scale to standardize page sizes; use Crop to remove unwanted borders.
Are my files private?
Yes. Scaling happens entirely in your browser using pdf-lib. Your PDF never leaves your device.
