Frequently Asked Questions

Why is it important to flatten a PDF form?

Flattening a PDF locks the entered data, preventing accidental or malicious modifications by the recipient. It also ensures the document displays consistently across different devices and PDF readers that might not properly render interactive fields.

Can I unflatten a PDF once it is saved?

No, flattening is an irreversible process. Once the interactive fields are converted to static text, they cannot be restored to editable form fields. This is why it is highly recommended to keep a backup of the original interactive file.

Does flattening a PDF change its file size?

Flattening may alter the file size, but usually not significantly. Its primary purpose is not compression, but rather security and display consistency by converting layers and interactive elements into basic static text and graphics.

Are digital signatures preserved when flattening a PDF?

Generally, flattening a PDF invalidates digital signatures because the structure of the document changes. If your document requires a digital signature, you should sign it after the flattening process is complete.
