Free Image to PDF Converter (JPG & PNG to PDF)
Convert multiple JPG, PNG, and WebP images into a single PDF.
How It Works & Calculation Method
Submitting photographic identity cards, expense receipts, medical bills, and academic portfolios frequently requires packaging individual photo files into a standardized, multi-page PDF document.
Our client-side Image to PDF converter embeds image bitmaps into standard PDF page containers locally, ensuring confidential medical and financial records remain 100% private.
The tool reads your selected image files, creates a blank PDF document using `pdf-lib`, and scales each image onto individual pages matching source aspect ratios.
It packages the compiled document binary for immediate download directly on your device.
Mathematical Formula
PDF Document = Sequential embedding of image bitmaps into calibrated PDF page containersWorked Example: Packaging 4 Receipts for Expense Reimbursement
An employee converts 4 smartphone photos of travel receipts into a single PDF file.
