Best Practices for Signing PDFs Digitally
While signing a PDF is quick and simple using your cell phone, maintaining some best practices ensures your documents are professional, secure, and error-free:
- Create Password Protection for Sensitive Files
Add a password to the document containing personal, legal, or financial information. This adds a layer of privacy.
- Add a Date if Needed
For document or contract signatures required by time, place the date next to your signature. This makes it clear and official when the document is signed.
- Check First Before Signing
Double-check the information in the PDF before signing. Verify for any mistakes, blank fields, or outdated details so you don’t accidentally sign something incorrectly.
- Have a Clean and Consistent Signature
Sign your signature as cleanly as possible, especially if you are finger-signing. Use a stylus if it is available, for better precision. After saving, use the same signature to ensure consistency on all documents.
- Place the Signature in its Proper Position
Click on the proper spot where the signature should go—presumably at the end of the form or in a specific field. Resize or move it so that it appears natural and can be read.
- Save a Copy Before Sending
Upon signing, save a signed copy of the PDF. It is advisable to retain both signed and original (unsigned) copies for your reference.
- Name the File Clearly
Use descriptive and professional file names such as Signed_Contract_JohnDoe.pdf rather than jumbled characters. It is easy to identify and appears more professional when shared.
By following these best practices, you create your signed PDFs neat, professional, and secure to deal with—just like in a conventional office environment, but quicker and without paper.
