If a PDF file has too many pages, you can easily split it using the print function of a browser. Follow these steps:

1. Navigate to the PDF file you want to split in your file manager.

2. Right-click on the file and choose "Open with" from the context menu.

3. Select the browser you want to use to open the file.

1. In the PDF viewer of your browser, look for a printer icon at the top right. Click on it to open the print dialog.

2. In the print dialog, make the following changes:

1. Set the destination: Choose "Save as PDF" (or a similar option).

2. Select custom pages: Choose "Customised" for the page range.

3. Define the pages: Specify the range of pages to be included in the new PDF (e.g., 1-1999). Ensure that no document is split across two files.

3. Click "Save" and name the new file. Use a consistent naming pattern, such as <<OriginalFilename>>_1.pdf.

1. Repeat the previous step to create the next part of the PDF.

- This time, set the starting page for the remaining pages (e.g., 2000-∞, depending on the document length).

2. Save this section with a corresponding file name, such as <<OriginalFilename>>_2.pdf.
