Split PDF by Size
Split a large PDF into smaller parts, each under a size you choose.
Your file is ready.
DownloadHow it works
- Choose a PDF file.
- Set the maximum size per part.
- Download each part separately.
Parts are split page by page: pages are added to a part until adding another page would exceed your size limit. The size of a part is measured after saving, so parts may be slightly under your limit.
