What Is Certificate Generator?
A Certificate Generator is a software tool designed to create professional-looking certificates in PDF format, allowing users to customize various elements such as title, recipient name, and description. It is commonly used by educators, trainers, and event organizers who need to award certificates of completion or achievement to individuals. One specific problem it solves is the tedious process of manually designing and formatting certificates, which can be time-consuming and prone to errors.
The tool is different from other certificate makers in that it offers a high degree of customization, including the ability to choose between landscape and portrait orientation, as well as customize the font, size, and color of various elements. For example, the code allows users to embed specific fonts, such as Helvetica and HelveticaBold, and define custom colors like gold, dark, mid, soft, and faint. It also features a word-wrapping function for descriptions, ensuring that text is neatly formatted within the certificate template.
It generates certificates with elegant double borders, centered typography, and a sophisticated layout, making it perfect for creating completion awards, training achievements, or recognition documents. With its ability to create certificate PDFs instantly, without requiring an account, it is an ideal solution for users who need to generate unlimited certificates quickly and efficiently. The tool's features, such as the signature area and optional ID field, make it a versatile certificate template that can be used in various contexts, including awarding certificates of completion or recognition.

Technical Guide
The Certificate Generator utilizes the pdf-lib library to create PDF documents from scratch, allowing for precise control over the layout and design of the certificates. When generating a certificate, it embeds specific fonts such as Helvetica and HelveticaBold using the `embedFont` method, which enables the use of these fonts throughout the document. The tool then creates a new page with the specified orientation, either landscape or portrait, and defines the dimensions of the page based on the A4 format standards. It uses the `drawRectangle` method to render decorative double borders around the certificate, with carefully chosen colors such as gold, dark, mid, soft, and faint. The recipient's name is rendered in large bold font using the `drawText` method, which allows for precise positioning and styling of the text.
The tool also employs a word-wrapping algorithm to ensure that descriptions fit neatly within the certificate template. This involves splitting the description into individual words and then iterating through them to determine when to wrap the text to the next line, based on the maximum allowed width of the page. The `widthOfTextAtSize` method is used to calculate the width of each word at a given font size, allowing the algorithm to make informed decisions about when to wrap the text. Optional fields such as the description, issuer, date, and ID are conditionally rendered based on user input, using the same precise layout control and styling options as the rest of the certificate. The final PDF document is then saved as a blob and made available for download using the `URL.createObjectURL` method.
