Filling in the pdf was great, however when I saved the file using "Save As" the text was not spaced out in the boxes but overwritten making it difficult to read.

The best security practices for protecting PDF files on a Macbook include using passwords for encryption, setting permissions for editing and printing, and using trusted software like pdfFiller. To implement password protection, use the 'Encrypt' feature during the PDF export process in Preview or upload your files to pdfFiller for advanced security options.

If you're using pdfFiller, you can easily manage PDF permissions through their platform, allowing for a more streamlined document workflow.

If you forget your PDF password on Macbook, consider using a dedicated PDF unlocking tool. Unfortunately, Preview won’t help in these cases. Tools like pdfFiller can assist in PDF recovery, but remember to use such services responsibly. Always keep a record of your passwords and store them in a secure password manager to avoid future issues.

Password protection restricts access to the document, while encryption transforms the content into a scrambled format that is unreadable without the proper key.

Always opt for PDF tools that support both features to maximize your document security.
