What is Image to PDF Converter?
An image to PDF converter combines one or more images into a single PDF document. PDF (Portable Document Format) is the universal standard for sharing documents across all devices and operating systems. Converting images to PDF is useful for creating portfolios, combining scanned documents, packaging photos for email, creating multi-page reports, and submitting forms that require PDF format.
Altairys's Image to PDF tool handles JPG, PNG, WebP, GIF, and BMP images, and lets you control page size, orientation, margin, and the order of pages. You can reorder images by dragging before converting, ensuring the final PDF is arranged exactly as you need. The conversion is performed entirely in your browser using the pdf-lib library — no files are uploaded, no account is required, and there's no limit on the number of images or the size of the output PDF.
Converting multiple scanned pages, photos from different devices, or graphics into a single unified PDF is one of the most common document tasks in offices and homes worldwide. Whether you're sending a signed contract, submitting an assignment, creating a digital album, or preparing a print-ready document, this tool converts your images to a professional-quality PDF in seconds.
