How PDFEditly Protects Your Privacy

Most online programs need users to upload their documents to distant servers before carrying out any operation. Privacy is, therefore, breached since confidential information is processed through third-party servers. Unlike other software, PDFEditly uses a different process to work with its documents.

Protect PDF is a browser-based program that carries out operations without uploading documents to any distant server. Consequently, it does not have any way of accessing, storing, or even looking at the documents that you use for your operations.

This makes the local processing capability very crucial for handling sensitive files such as contracts, financial documents, tax forms, medical data, HR documentation, and ID cards.

The fact that your document is processed locally gives you an extra layer of privacy that is not available with many other applications.

Documents You Should Password Protect

It is not always necessary to use security for PDF files, but some documents do need to be kept confidential. Some examples of when it may be useful to use password secure PDF include the following:

  • Contracts
  • Non-disclosures
  • Proposals to clients
  • Financial reports
  • Taxes
  • Medical records
  • Insurance documents
  • Business plans
  • ID documents
  • Letters or correspondence

Using a password will make sure that only those who have permission can open the document.

Tips for Creating Strong PDF Passwords

One of the most important steps involved in PDF password protection is to create an effective password.

These are some suggestions:

  • A password should consist of a minimum of 12 characters.
  • A password should include both uppercase and lowercase letters.
  • Numbers and special characters should be added to the password.
  • No use of names or birthdates.
  • Passwords should never be repeated from another account.
  • The password must be stored safely.

Passwords must be updated periodically for highly confidential documents.

Protected PDF vs Unprotected PDF

All PDF files do not provide equal levels of security. If a PDF file is unprotected, then any individual who has access to the PDF file can view it, hence making confidential information available to those who should not have access to it. On the other hand, if the file is password-protected, an **individual **will need to enter the password to access the document.

The comparison clearly shows why many organizations choose to encrypt PDF documents before sharing them externally.

Protected PDF vs Unprotected PDF
