Maximum File Size & Page Limits

To ensure reliable fax transmission, VoltFax applies upload and transmission limits.

Limits may vary depending on your subscription plan.

Typical limits include:

• Maximum file upload size per fax
• Maximum number of pages per transmission
• Maximum number of attachments

If your fax exceeds your plan’s limits, consider:

• Splitting large documents into multiple faxes
• Compressing PDF files
• Removing unnecessary pages
• Upgrading your subscription for higher limits

If a transmission exceeds the allowed limits, VoltFax will notify you before the fax is sent.
