Upload only the pages you need from a PDF before processing.

In Memo v8 and beyond, you can split a PDF during upload so your notebook only uses selected pages.

## **How to split pages**

1.  Open your notebook and go to the **Sources** panel.

2.  Click **Add source**.

3.  Upload your PDF (drag/drop or choose file).

4.  In **Selected files**, click **Split pages** next to the PDF.

5.  Choose pages:

    - Click page thumbnails to select/deselect.

    - Use **Start** + **End** and click **Select range** for a continuous range.

    - Use **Shift + click** to quickly select a range.

6.  Click **Apply page split**.

7.  Click **Add 1 source** (or **Add X sources**).

## **What happens in v8** and beyond

- Only the selected pages are uploaded and processed.

- If all pages are selected, Memo uploads the original PDF unchanged.

- Page order is preserved (ascending order).

- You can set different split selections for multiple PDFs in the same upload session.

## **Troubleshooting**

- **No “Split pages” button?**  
  Make sure you uploaded a PDF and it appears in the **Selected files** list.

- **“Apply page split” is disabled?**  
  Select at least one page.

- **Range error?**  
  Start/end must be whole numbers within the document page count.

- **Upload stuck on “Preparing split file…”?**  
  Wait for local split prep to finish, especially for large PDFs.
