Canonical: https://helpers.aibrush.co/en/add-margins

## When to use it

Add Margins helps when a PDF needs extra room for a binder edge, handwritten notes, stamps, or a signature area.

## Local processing

Your PDF is rebuilt in the browser. Selected pages are processed locally, and the file is not uploaded to AiBrush Helpers.

## How to add margins

1. **Upload** — Choose the PDF that needs margin space.
2. **Set margins** — Use one uniform margin or custom top, right, bottom, and left values.
3. **Choose pages** — Apply margins to all pages or select pages in the page rail.
4. **Download** — Save the PDF with margins from your browser.

## Add Margins FAQ

### Will this cut off existing content?

No. Expand page size keeps content at full scale, while keep-page-size mode scales content inward.

### Can I add margins to selected pages only?

Yes. Choose Selected pages and pick the pages in the rail before saving.

### Are my PDF files uploaded?

No. Margin changes run locally in your browser.
