# Build a PDF from your scan — pages to one file, no upload

> Assemble your captured or imported pages into a single PDF with your choice of page size and margins, built locally with pdf-lib. No upload, no account.

Assemble your captured or imported pages into a single PDF, choosing the page size and margins. The document is built in your browser with pdf-lib, so it's never uploaded.

The point of scanning is usually one shareable file, and this step turns a stack of enhanced pages into exactly that — a clean multi-page PDF sized to A4 or Letter with sensible margins. Building it locally means the finished document, however sensitive, is created without a round-trip.

Order matters here, so arrange pages before building; margins and page size make the result print correctly rather than getting cropped by a printer.

If you need the text to be selectable, use Searchable OCR; to email it, run Compress scan; and to remove sensitive bits first, use Scrub & redact.

## How to

1. **Order pages.** Arrange your scanned pages into the final sequence.
2. **Set the page.** Pick a page size (A4, Letter) and margins.
3. **Build.** Combine the pages into one PDF locally.
4. **Download.** Save the finished PDF to your device.

## FAQ

### How do I combine several scanned pages into one PDF?

Put the pages in order, choose your page size and margins, and build — the tool merges them into a single multi-page PDF you can download.

### Can I choose A4 or Letter?

Yes. Set the page size and margins so the output matches your region's standard and prints correctly.

### Should I add a text layer?

If you want to search or copy from the document, use Searchable OCR instead, which produces a PDF with an invisible selectable text layer.

### Is the PDF built on a server?

No. It's assembled with pdf-lib in your browser, so your pages stay local from capture to finished file.
