Choose a PDF, set the maximum size per part, and the document is split into consecutive parts that stay under the limit — for email attachments and upload caps. One honest exception: if a single page is bigger than your limit all by itself, it forms its own part and the result report flags it clearly (a page cannot be split further — compress it first if it must fit). Parts download as a ZIP (or a single PDF if everything fits in one part). Runs fully in your browser — nothing is uploaded.
Too big to email? Set the cap and get back tidy consecutive parts, each one under it, ready to send one by one.

Split a PDF into consecutive parts that stay under a size limit you set — for email attachment caps and upload limits. Parts come as a ZIP of PDFs, or a single PDF if it already fits. A single page that exceeds the cap on its own is flagged honestly in the result, never passed off as under it.
A 9 MB survey PDF must go through a form capped at 2 MB per file. Split at 2 MB, it becomes five sequential parts, each under the cap, each named and in order — five uploads later, the whole survey has arrived.
The splitter measures honestly: it test-builds each candidate part with the PDF library and weighs the actual bytes, rather than guessing from the input file — because a page’s share of a PDF is not its size divided by page count (shared fonts and images distort naive maths). A single page bigger than the cap goes into a part of its own and that part exceeds the cap by necessity; the packing still keeps every other part under.
Because pages are not equal: one photo page can outweigh thirty text pages. Only measuring real parts guarantees each file passes the upload check.
A single page in it exceeds the cap on its own, and a page cannot be split further. Compress that part (Compress PDF) or send it by another route.
Your file’s name plus -part-1, -part-2, … inside the ZIP (or as the single PDF when one part suffices), so they sort and send in order.
Yes — Merge PDF rejoins the parts in order into the original sequence.
No. Splitting happens in your browser.
