What this tool does
Splitting a PDF cuts one file into parts of a fixed number of pages and packages them into a single ZIP, ready for batch sending or separate archiving.
Every part keeps the original page size and selectable text layer; nothing is re-encoded. It all runs in your browser — no upload.
How many pages per part? If the goal is beating an upload limit, estimate first: divide the original size by the number of parts and leave about 20% headroom, because each part repeats fonts and shared resources and the total usually exceeds the original. If the goal is sending a document chapter by chapter, choose page counts per chapter rather than a fixed number — chapters are usually bookmarks, so check the viewer for how many pages each one spans.

FAQ
Why a ZIP instead of separate downloads?
Browsers tend to block repeated downloads. One ZIP is more reliable and easier to keep organized.
Can I split by page ranges?
This tool splits by a fixed page count. For ranges like "only pages 3–8", use the extract-pages tool.
Are the parts still editable?
The text layer is preserved, so each part can be selected, copied and searched just like the original.
Can I split a protected PDF?
No. Password-protected files are rejected; this tool never cracks passwords.
Are the files inside the ZIP compressed?
No, the ZIP uses uncompressed store mode. PDFs and images are already compressed, so recompressing gains almost nothing and costs noticeable time.
What is the limit?
Up to 100MB per file. For larger files, compress them first, then split.
