Split the PDF using Adobe Acrobat Organize Pages tool

Use Adobe Acrobat's built-in feature to split the document by the number of pages, file size, or top-level bookmarks.

Open the Organize Pages tool

Open your large PDF in Adobe Acrobat. Go to the top menu and choose 'All tools', then select 'Organize pages'.

Select the Split option

Click the 'Split' button located in the secondary toolbar.

Choose your split criteria

A dropdown menu will appear. Select your preferred split method, such as by 'Number of pages', 'File size', or 'Top-level bookmarks', and specify the exact parameters.

Save and upload

Click 'Split' to process the document and save the smaller PDFs to your computer. You can now upload each part to the conversion service separately.

Frequently Asked Questions

Why does my online PDF converter say the file is too large?

Free online conversion services often restrict processing power and server load by capping file sizes (e.g., maximum 10MB) or page counts (e.g., maximum 50 pages). Splitting the file helps bypass these limitations.

Will splitting my PDF reduce its text or image quality?

No, splitting a PDF simply divides the existing pages into separate files. It does not compress the document or alter the resolution of the text or embedded images.

Can I split a PDF for free without Adobe Acrobat?

Yes, you can use free desktop alternatives like WPS Office to split PDFs. Mac users can also use the built-in Preview app to drag and drop specific pages into a new document.

How do I recombine the files after converting them to Word?

Once you have converted the smaller PDFs to Word documents, open the first document, place your cursor at the end, and go to Insert > Object > Text from File to merge the remaining Word documents together.
