Frequently Asked Questions

Will my content be cropped if I resize to a smaller page?

No — content scales proportionally. If you want to crop instead, use the Crop tool.

Difference between Resize and Crop?

Resize changes the page dimensions (scales content). Crop changes the visible region without scaling.

Does this affect text quality?

Text is vector-based in PDFs, so it scales perfectly. Only embedded raster images can lose quality on extreme upscale.
