Image to PDF Conversion - Complete Guide
Converting images to PDF format is essential for creating professional documents, portfolios, and shareable files. PDF (Portable Document Format) preserves image quality while providing a standardized format that can be viewed on any device. Our free online converter uses the jsPDF library combined with HTML5 Canvas to create high-quality PDF documents from your images, all processed locally in your browser.
How Image to PDF Conversion Works
When you upload images to our converter, each image is loaded onto an HTML5 Canvas element. The canvas converts the image to a data URL format that can be embedded in a PDF. We use the jsPDF library to create a new PDF document, add each image as a page, and apply your selected settings (page size, orientation, margins). The entire PDF is generated in your browser and downloaded directly to your device - no server processing required.

PDF Page Size Options
Our converter offers three page size options to suit your needs. A4 (210x297mm) is the international standard used in most countries. Letter (8.5x11 inches) is the North American standard. Fit to Image automatically sizes each page to match the image dimensions, preserving the original aspect ratio without any white space. Choose the orientation (portrait or landscape) that best fits your images.
