The Acrobat Split PDF online tool lets you quickly split and separate PDF pages into up to 20 new PDF files without the need to download additional software. First, select a PDF of 1,500 pages or less, and sign in to Acrobat. Then insert as many as 19 divider lines to determine the number of pages desired in each split PDF file. Finally, click Save. Acrobat will split your PDF based on the divider lines and save your new split PDF files to a folder of your choice.

Although splitting PDF pages does not necessarily reduce the quality of your document, you can use Adobe Acrobat and follow these steps to get quality document resolution after you split the pages:

1. Open the PDF in Acrobat.
2. Select Tools > Organize Pages > Split.
3. In the Split dropdown menu, you can specify if you want to split the PDF file by number of pages, maximum file size, or top-level bookmarks.
4. Select Output Options to specify a target folder for the split PDF files, and set file labeling preferences.
5. Click OK > Split to start the process.
6. Name the new PDF file and click Save.

When using the PDF splitter tool, the quality of the new PDF will remain the same.

Take these steps to split a PDF on your Mac using Preview:

1. Open your PDF in the Preview app.
2. Open the thumbnail view and select the page or pages you would like to separate.
3. Drag and drop the pages to your desktop or to another folder.

You can continue to split the PDF by repeating the last two steps. You now have new PDFs created from your old one, and you can share or save them as needed. If you need to edit your PDF even more, consider using Acrobat online services.

You can split single PDFs with a file size of 1GB or less into separate PDF files using Acrobat online PDF tools. Simply drag and drop files into the PDF splitter tool using the instructions above.

After you select pages and set up separator lines, click Save. Acrobat saves the split PDFs in an Adobe cloud storage folder within your Acrobat account. You can rename, download, or share the new PDFs with others.

If you need to do more with PDFs beyond splitting files, you can start an Adobe Acrobat Pro 7-day free trial on Mac or Windows. The Acrobat PDF editor tools let you edit PDFs, merge PDFs, reorder individual pages, extract pages, delete pages, rotate PDF pages, reduce file size, set passwords and permissions, and add bookmarks. You can also convert images like PNGs or JPGs and convert PDFs to and from Microsoft Word, PowerPoint (PPT), and Excel.
