Create Professional Business Letters as PDF Create formal letters in PDF format with proper formatting.

The tool works by utilizing React to manage state and handle user input, storing values such as sender name, address, recipient details, date, subject, salutation, body text, and closing in useState variables. When the generate button is clicked, it triggers a callback function that imports pdf-lib, a JavaScript library for creating and manipulating PDF documents. The tool then creates a new PDF document using PDFDocument.create and embeds Helvetica fonts using doc.embedFont. It calculates page dimensions, margin, content width, font size, and line height to properly position text elements within the page.

The ensureSpace function checks if there is enough space on the current page for adding new text, and if not, it adds a new page to the document. The drawText function uses page.drawText to render text at specified coordinates with chosen font, size, and color. The wrapText function splits input text into lines that fit within the content width by calculating the width of each word using font.widthOfTextAtSize. This allows for proper wrapping of multi-paragraph body text.

The tool then populates the PDF document with user-provided data, including sender details, date, recipient address, subject line, salutation, body text, and closing. It uses a combination of font sizes, styles, and colors to achieve standard business letter formatting. Once all elements are added, the tool saves the PDF document as a blob using doc.save and creates a downloadable link for the user using URL.createObjectURL. The generated PDF file is formatted according to standard business conventions with proper spacing, alignment, and typography, making it suitable for formal correspondence.

The pdf-lib library handles low-level details of PDF creation, allowing the tool to focus on layout and content generation. By leveraging React for state management and pdf-lib for PDF creation, the tool provides a simple and efficient way to generate professional-looking business letters as PDF documents. The use of Helvetica font with specific sizes and styles ensures consistency in formatting, while features like automatic date formatting and customizable salutations and closings make it easy to create formal correspondence quickly and easily.
