Upload Guide
Document Upload Workflows
Signly supports multiple upload modes for different signing scenarios.
Upload Modes
Single Document
The simplest flow — upload one PDF, send to one or more signers:
- Click Upload Document
- Select your PDF
- Add signers with their email addresses
- Configure signing order (optional)
- Confirm credits and send
Bulk Upload
Upload multiple documents at once:
- Click Bulk Upload
- Select multiple PDFs (or drag & drop)
- For each document, assign signers
- Send all documents simultaneously
Sequential Signing
Documents can require signatures in a specific order:
- Upload your document
- Add multiple signers
- Set signing order for each
- Signer 1 signs first, then Signer 2 is notified, and so on
Example: Contract Approval
Manager signs → Director signs → CEO signs
Each signer is notified only when it's their turn.
Supported File Types
| Format | Max Size | Notes |
