How to Split PDF into Chunks
1. Upload your PDF document. The tool displays the total page count so you can decide on an appropriate chunk size.
2. Enter the number of pages per chunk. For example, enter 10 to create chunks of 10 pages each. A 47-page PDF becomes 5 files: four 10-page chunks and one 7-page chunk.
3. Click Split into Chunks to generate multiple PDF files. Download them as a ZIP archive. All processing happens locally without any uploads.
Example Use Cases

Frequently Asked Questions
How do you afford to run this chunk splitter without ads?
By not running servers that process your files. This chunk splitter runs entirely in your browser. Every split happens on your device. Since there are no server costs, there is no need to sell advertising or data to keep it running. We are an IT solutions company with enterprise clients.
What happens to my PDF during chunk splitting?
Your PDF stays on your device throughout the entire process. This chunk splitter handles all processing in-browser with JavaScript. Your document is read from your device, split in memory, and served as downloads. All without any server communication. We cannot see, store, or harvest your PDF.
What if the page count is not evenly divisible?
The last chunk will contain the remaining pages. For example, splitting a 47-page PDF into chunks of 10 produces five files: four 10-page chunks and one 7-page chunk. All pages are preserved.
Can I specify custom chunk sizes?
Yes. Enter any positive integer for the chunk size. Common sizes are 5, 10, 20, or 25 pages per chunk. Choose based on your needs such as email attachment limits or section organization.
Is there a maximum chunk size?
There is no maximum. You can enter any positive integer. However, very large chunk sizes may produce fewer output files. For a 100-page PDF, a chunk size of 50 produces 2 files, while a chunk size of 10 produces 10 files.
