PDF Merge

Combine 2–20 PDFs into one document

Merge multiple PDF files into a single document in one API call. Upload 2–20 files, optionally reorder them with an index list, and receive the merged PDF binary. Response headers tell you total pages and per-file page counts.

How it works

Accepts multipart file uploads, merges them in order (or the specified order), and returns the combined PDF binary.
