📄 About PDF

PDF (Portable Document Format) is a file format developed by Adobe to present documents, including text formatting and images, in a manner independent of application software, hardware, and operating systems. Each PDF file encapsulates a complete description of a fixed-layout flat document, including the text, fonts, vector graphics, raster images, and other information needed to display it.

The main advantages of PDF include: maintaining document formatting consistency, cross-platform compatibility, security (can be password-protected and have permissions set), and suitability for printing and professional sharing.

⚙️ How Conversion Works

Image to PDF conversion in this tool is performed entirely in your browser using JavaScript, primarily relying on the powerful jsPDF library.

  1. Image Selection and Reading: After you select one or more image files using the button above, the browser uses JavaScript to read the data of these image files.
  2. Order Adjustment: You can adjust the order of the selected images to determine their arrangement in the final PDF.
  3. PDF Document Creation: When you click "Convert to PDF", jsPDF creates a new, blank PDF document in your browser's memory.
  4. Image Embedding: The reordered images are processed one by one. Each image's data is read, and jsPDF functions are used to draw it onto a new page in the PDF document. The tool attempts to automatically resize images to fit standard PDF pages (like A4) while preserving the original aspect ratio as much as possible.
  5. PDF Generation and Download: Once all selected images have been added to the PDF document, jsPDF compiles this in-memory PDF document into the final .pdf file and automatically triggers the browser's download action, allowing you to save it locally.
