Flatbed scanners are fast, but many only scan one side at a time. The result: a PDF of all the odd pages and a separate PDF of all the even pages — and now you need to weave them together into a single document in the right order. Interleaving pages by hand in a PDF editor is tedious and error-prone. The Alternate Mix tool does it automatically: upload both PDFs and it produces a single merged file where page 1 comes from the first document, page 2 from the second, page 3 from the first again, and so on. This pattern — called alternating or interleaved merge — is the standard solution for single-sided scanner workflows. It also applies beyond scanning. Publishers combining right-hand and left-hand page layouts, teachers merging question and answer sheets, and engineers assembling alternating sections of a technical specification all face the same structural problem. A generic PDF merge tool appends documents end-to-end, which is not what you need. Alternate Mix understands the page-interleave pattern and handles it in a single operation. The tool supports both forward and reverse interleaving. If your back-scan PDF came out in reverse order — a common behaviour with sheet-fed scanners that flip the stack — you can tell dokk.ai to reverse the second document before mixing. This single checkbox saves you from manually reordering dozens or hundreds of pages before combining them. Output quality is identical to the source documents. No rasterisation occurs; the PDF structure is rebuilt by combining page objects from both input files, so text, vectors, annotations, and embedded fonts are all preserved exactly. The result is a valid, standards-compliant PDF that opens correctly in any reader. When your workflow requires further steps — such as applying OCR after combining scans, compressing the merged file for email, or reordering a few pages that were placed incorrectly — dokk.ai's Merge PDF, Split PDF, and Reorder Pages tools are available alongside. Files are processed over TLS and deleted within 60 minutes, keeping your scanned documents private and compliant with GDPR requirements.
