Questions
What is the difference between splitting and extracting?
Splitting breaks the whole document into several files at once — one per page, or in fixed chunks. Extracting pulls out a specific range and gives you one file. Use Extract PDF Pages if you only want pages 4–7.
Why is the output capped at 200 files?
Each split page becomes a separate PDF built in memory, and browsers get unhappy holding hundreds of blobs at once. If you need more, split in chunks first, then split each chunk.
Are the resulting files smaller?
Each file is smaller than the original, but the total across all of them is usually slightly larger. Every PDF has to carry its own copy of any shared fonts and resources.
