File Size Constraints

• The maximum size of a single document is 16 MB. Smaller documents yield better performance — we recommend under 5 MB per document.
• If your organization uses Salesforce or Microsoft SharePoint connectors, the file size maximum is 5 MB per document.
• If your organization uses Salesforce connectors, the maximum number of documents that can be added to a transaction is ten (10).
• If you enable email delivery while configuring a recipient, attachments larger than 5 MB are not supported.

File Name Constraints

• Document file names should not contain any of the following comma-separated characters: *, /, \, :, <, >, |, ?, ".
• A document's name cannot contain the string esigned.

General File Constraints

• We recommend that you do not use PDF documents that make use of XML Forms Architecture. For more information, see XFA Support.
• Do not upload password-protected or corrupted documents. These will generate an error.
• OneSpan strongly recommends that you scan a PDF for syntax errors (e.g., by using Adobe's Preflight tool), and resolve any errors before you add the document to a transaction.
• PDFs with the NeedAppearances flag set to true are not currently supported.
