- Making a document print correctly on paper it was not laid out for.
- Main limitation
- Content is scaled to fit the new page, so a change of aspect ratio leaves margins on two sides rather than cropping.

Why use iBuildPDF
A merged bundle of scans, exports and downloads often contains three different page sizes, which makes it print badly and look unfinished. One consistent size fixes both.
How it works
Each page is placed on a new page of the target size and scaled to fit, keeping its aspect ratio and centring it. Content is never stretched — a landscape page on a portrait sheet gets margins rather than distortion.
Frequently asked questions
Does text stay selectable?
Yes. Pages are embedded as scaled objects rather than re-rendered, so text remains live and searchable.
What happens to landscape pages?
They are scaled to fit the target page and centred, keeping their shape. If you would rather they rotate to fill the sheet, use Rotate PDF first and then resize.
Which sizes can I choose?
A4, Letter, Legal, A3 and A5, each as portrait or landscape — or keep each page's orientation, which sets portrait and landscape pages separately so a document that mixes both stays that way at one paper size.
Why does my content have white bands down the sides?
Because the page you started with is a different shape from the one you chose. The content is scaled to fit and centred rather than stretched, so a mismatch in proportions becomes margins. Stretching would fill the sheet and make every diagram on it wrong.
Does resizing crop anything?
No. Everything on the page is kept and scaled as one block. If you want the edges removed rather than shrunk — a scanner border, for instance — Crop PDF is the tool for that.
Will the file get bigger?
Usually not by much. Pages are embedded as scaled objects rather than re-rendered, and fonts and images are shared across the whole document instead of being copied once per page, so the result is normally close to the original in size.
Will it print correctly now?
The page size recorded in the file is what a printer reads, so you should no longer need fit to page in the print dialogue. A reader set to shrink oversized pages will still do so until you turn that setting off.
