5 Best Practices When It Comes to Faxing PDFs

Faxing a PDF online through efficient fax services can indeed be a highly convenient and effective method to transmit documents. Here are five essential best practices to consider when faxing PDFs:

Use high-quality PDFs. Make sure to fax high-quality PDFs. Low-quality PDFs can be difficult to read and may become illegible when faxed, resulting in a failed transmission.
Compress PDFs. PDFs can be quite large, which can cause problems during transmission. Compressing these files can reduce their size, which can help expedite the faxing process.
Use a cover page. When faxing a PDF online, consider using a cover page. The cover page acts as an additional layer of security, preventing anyone from accidentally viewing the contents of your fax.
Encrypt sensitive PDFs. If you’re faxing a PDF that contains sensitive information, it’s a good idea to encrypt the file before sending it. An encrypted file will be much harder to intercept as it will be unreadable to anyone with unauthorized access.
Confirm receipt. Once you’ve faxed a PDF, confirming receipt with the recipient is always a good idea. This way, it will be easier for you to resolve any issues before they turn into something serious.
