Max File Upload Size

❓ What is the default maximum file size that can be uploaded to OpenSign?​

  • Self-Hosted Users: Maximum file size is 80 MB
  • Cloud Users: Maximum file size is 10 MB
    (Includes an additional +10 MB buffer to prevent signing failures when you add images during signing which increases the file size.)

❓ Can the file size limit be increased?​

  • Cloud Hosting: Yes — on request, the limit can be increased up to 90 MB for enterprise user
  • Self-Hosting: No — the limit is fixed at 80 MB and cannot be modified

⚠️ Note: There is a hard server-side limit of 100 MB, which cannot be exceeded.

❓ What happens if a file exceeds the maximum size?​

If a file exceeds the allowed limit:

  • The upload is rejected
  • A validation error message is returned to the user
