Frequently Asked Questions
Will content stretch?
No. Content is centered and preserves its aspect ratio, possibly leaving margins. Forms and annotations become static page content.
How does resizing differ from cropping?
Resizing proportionally fits content onto a new sheet and may add margins. Cropping changes the visible boundary rather than scaling the whole page.
What units and custom sizes are supported?
Width and height are in millimeters, with a 10–2000 mm input range. Choose a preset or custom size and check landscape versus portrait orientation.
Does enlarging the paper sharpen a blurry scan?
No. A larger sheet cannot recover missing scan detail and can make blur more visible. Use a clearer original or an appropriate display size.
Can I resize only some pages?
Selected pages are resized; unselected pages retain their size. A result may contain mixed paper sizes, so check the selection and all-page preview.
