Why insert blank pages?
When compiling physical booklets or dual-sided corporate reports, formatting mandates often state that major sections must strictly begin on odd-numbered, right-hand side pages. If a prior section finishes on an odd page, continuing normally will break the print format rule.
By visually mapping your uploaded document within the browser viewport, FreeTools Blank Page Inserter allows you to strategically define exactly where whitespace is required in your document stream. You simply locate the gap and click the `+` axis. The internal `pdf-lib` script immediately instantiates a pure 595x841 pixel empty vector canvas in that spot when saving, bypassing any need for remote server uploads and mitigating IP interception vectors completely.
