Conversion Process

1. Image Loading: The browser's File API reads the selected JPG files.
2. Canvas Rendering: Each image is drawn onto an HTML canvas element to ensure proper sizing.
3. PDF Generation: Using the jsPDF library, a new PDF document is created with each image added as a page.
4. Compression: Optional quality settings can be applied to reduce file size while maintaining readability.

Key Formulas

The tool calculates PDF page dimensions based on the image aspect ratio:

pdfPageWidth = imageWidth * (72 / imageDPI)

pdfPageHeight = imageHeight * (72 / imageDPI)

Where 72 is the standard DPI for PDF documents, and imageDPI is the resolution of the uploaded image.

Quality Preservation

The tool maintains image quality by:

• Preserving the original image dimensions
• Using lossless compression when possible
• Maintaining color depth and resolution
