About Convert Image to PDF

Master Merge converts a single image (JPG, PNG, or WEBP) into a PDF document. Useful for sharing receipts, ID scans, screenshots, or photos in a universally readable format.

The PDF page size adapts to the image dimensions, and quality is preserved at the original resolution. Conversion runs in your browser using pdf-lib, so even sensitive scans like passports stay private.
