Multiple Signatures PDF — Multi-Signer & Team Signing

Board resolutions and MSAs need more than one name. Emailing an editable PDF around is how pages get swapped. Premium routing coordinates order; each person still signs in their own Web Worker. This is not a folder of unrelated files being “batch signed” on a VPS, and it is not a PKI ceremony.

Multi-signer routing and collaborative PDF signing require Pro. Upgrade via Lemon Squeezy for team signatures, sequential counter-signing, and unlimited bulk workflows.

One document, several people, still local per pass

Search results for “batch sign” often mean stamping the same PNG on 200 PDFs. That is not this page. This page is collaborative: one agreement, sequential or parallel counterparties, Premium routing links. The master file is not parked in our vault.

Free vs Premium

You signing once is free. Asking three directors to sign in order is Premium. Lemon Squeezy unlocks routing and bulk volume — not a different flatten engine.

Do not mix this with OCR batches

There is no “OCR a folder then sign.” Encrypted PDFs need Unlock first (with a password you know). Compress after if emailing the final packet.

Audit trail honesty

We coordinate links; we do not keep a DocuSign-style certificate log of the PDF bytes. Keep your own records of who signed when.

How it works

  1. 1

    Prepare the PDF locally

    Your first mark still happens in pdf-lib, no upload.

  2. 2

    Upgrade for routing

    Premium sends counterparties through their own local pass.

  3. 3

    Each signer flattens

    Marks merge into one file without us storing a cloud original.

Use cases

Board resolutions

Several directors, one governance PDF.

Partnership agreements

Sequential partners instead of email ping-pong.

Sales plus counsel plus client

Shared order without a central vault of the contract.

Vendor MSAs

Procurement teams that need more than one internal mark.

Problems we solve

Editable copies in email

Anyone can swap a page. Routed flattening keeps a controlled order.

Per-seat envelope fees

Premium routing via Lemon Squeezy is the Convertify4u answer — not enterprise envelope pricing.

Manual scan merges

Photographing each signature page destroys structure. Flattened routing keeps one PDF.

Trust & privacy

Premium routing

Multi-person collection is the paid collaboration feature.

Local per signer

Each pass is still a Web Worker. We do not host the master file.

Flattened final

All marks become page content in one output.
