Split PDF by file size

Split the PDF into multiple copies according to the set file size. Set a 6MB PDF to be split into 1MB file sizes, and split it into 6 copies. Each copy will be as close as possible but not more than 1MB (if a single page of the PDF does not exceed 1MB). Turning on compression can prevent the split PDF files from being too large.

Split PDF by File Size

Efficiently manage your large documents with our Split PDF by file size tool. This specialized utility allows you to divide a single large PDF into multiple smaller copies based on your specific target size requirements. For example, if you have a 6MB document and set the limit to 1MB, our tool will intelligently partition it into 6 separate files. Each output file will be as close to the target size as possible without exceeding it, provided a single page does not naturally exceed the limit.

Frequently Asked Questions


How do I split a PDF into specific sizes?

Simply select your PDF, enter the desired maximum file size (e.g., 200KB or 2MB), and click "Start". The tool will group pages together until the size limit is reached for each segment.


What happens if one page is larger than the limit?

If a single page is inherently larger than your set limit, the tool will isolate that page into its own file. Enabling the compression feature can help bring such pages under the limit.
