Questions? We've got answers.

Can I split a password-protected PDF?

Yes, you can split a password-protected PDF in Adobe Acrobat after unlocking it using the correct password. Once the document is unlocked, you can proceed to split it into multiple files or extract specific pages. Be sure to save the new files after splitting to preserve your changes.

Is there a limit on the number of pages I can split in a PDF?

Adobe Acrobat allows you to split large PDFs into multiple smaller files, but the number of pages per file may vary depending on file size and system performance. While there’s no strict page limit, splitting extremely large PDFs may take longer. It’s best to split them into manageable sections to ensure optimal performance.

How do I split a PDF by bookmarks?

To split a PDF by bookmarks, open the document in Adobe Acrobat and choose “Organise Pages” > “Split.” Select “Top-level Bookmarks” as your splitting method to create separate files based on the bookmark structure. This is particularly useful for documents that contain clearly defined chapters or sections.

Can I split a PDF and keep the original file intact?

Yes, splitting a PDF does not modify the original file. The newly created documents are saved separately, ensuring that your original PDF remains intact. You can rename and organise the split files as needed after completing the process.

How do I split a scanned PDF document?

If the PDF is a scanned document, use Adobe Acrobat’s OCR (Optical Character Recognition) feature to convert it into editable text before splitting. Once converted, you can split the document using the “Organise Pages” > “Split” option. This process ensures that scanned content is accurately preserved in the split files.

Does splitting a PDF affect the quality of the document?

No, splitting a PDF does not compromise the quality or resolution of the original document. Each split file retains the same visual and text quality as the original. This ensures that your documents remain clear and professional after splitting.

Can I split a PDF into equal-sized files?

Yes, Adobe Acrobat allows you to split a PDF into equal-sized files by specifying the desired number of pages per file. You can define the page range to ensure each split file contains an equal number of pages. This is especially useful when you need to distribute content evenly across multiple files.

How can I split multiple PDFs at once?

To split multiple PDFs simultaneously, use Adobe Acrobat’s batch processing feature. This allows you to apply the split action to several documents in one go, saving time and effort. You can also customise how the documents are split, ensuring consistency across all files.
