Technical Specification
JPEG Image Compilation & PDF Document Assembly Engine
Overview
The ToolsForges JPG-to-PDF converter compiles multiple JPEG images into a single, properly formatted PDF document entirely within the browser. Upload your images, arrange them in the desired order, configure page size and orientation, and receive a downloadable PDF that preserves image quality and aspect ratios.
Feature Specifications
- Multi-Image CompilationUpload and combine multiple JPEG images into a single PDF document, with each image occupying a separate page maintaining its original aspect ratio and visual quality.
- Page Size ConfigurationSelect from standard page sizes — A4, Letter, Legal, and custom dimensions — with portrait or landscape orientation to match your output requirements.
- Image Arrangement ControlDrag and reorder uploaded images to control the page sequence in the final PDF, ensuring documents follow the intended narrative or organizational flow.
- Margin and Spacing OptionsConfigure page margins and inter-image spacing to produce professionally formatted documents with appropriate whitespace for readability and print compatibility.
Architecture
The converter uses the browser's Canvas API for image rendering and the jsPDF library for PDF assembly. Each image is loaded into a canvas element, scaled to fit the selected page dimensions, and appended to the PDF document as an image stream.
Frequently Asked Questions
What image formats are supported besides JPEG?
The primary input format is JPEG. PNG images with transparency are also supported, with transparent areas rendered as white in the PDF output.
Can I add text or headers to the PDF?
The current implementation compiles images into PDF pages without additional text overlay. Text addition is planned for a future release.
What is the maximum number of images?
The tool handles practical numbers of images (up to several hundred) efficiently. Very large batches may experience processing delays depending on individual image sizes.
Is my image data stored?
No. All uploaded images and generated PDF files are processed entirely within your browser. No image content is transmitted to external servers.
