Images to PDF Converter

PDF (Portable Document Format) was created by Adobe in 1993 as a universal format for document exchange that preserves layout and appearance across devices and operating systems. A PDF file contains a structured tree of objects defining pages, content streams, resources, and metadata.



This converter creates a PDF by generating a page for each uploaded image. Using the jsPDF library (a JavaScript PDF generation library), it creates a new PDF document, calculates the optimal page dimensions to fit each image, and draws the image data into the PDF content stream. Images are embedded as compressed XObject streams within the PDF's internal structure.



The page size can match the image dimensions exactly (creating a PDF where each page is the same size as the image), or images can be fitted to standard paper sizes (A4, Letter) with appropriate scaling. The resulting PDF contains the images as embedded raster graphics. All processing happens in your browser—your images never leave your device.

1. Document Scanning and Archiving
When scanning physical documents with a phone or flatbed scanner, individual page scans are saved as images. Converting these to a multi-page PDF creates a proper document archive that is easier to share, email, and store than a folder of individual image files. PDFs also support text layer addition through OCR tools if needed later.



2. Sharing Photos as a Coherent Document
Portfolio presentations, insurance claim photo documentation, real estate inspection reports, and event photography collections are easier to share as a single PDF than as individual image files. Recipients can view all images in sequence without needing to download a zip archive and open multiple files.



3. Regulatory and Compliance Submissions
Many regulatory portals, insurance platforms, and government forms accept only PDF submissions. Converting required documentation photos (ID documents, receipts, medical records) to PDF format meets these requirements without needing specialized software.



4. Print-Ready File Creation
Creating print-ready files from photos requires combining multiple images in the correct order and dimensions. Converting images to PDF with specific page sizes (A4, Letter) creates files that print predictably from standard print dialogs, with consistent margins and scale.



5. E-Book and Photo Book Assembly
Simple photo books, travel diaries, and illustrated documents can be assembled from individual image pages. Converting images to PDF provides a shareable, printable format that maintains the visual sequence and quality of the original images.

• Arrange images before converting: The page order in the PDF will match the image order you upload. Review and drag to reorder images before converting to avoid creating a PDF that needs rearranging afterward.



• Compress images first for smaller PDF size: PDF files embedded with full-quality images can be very large. Compressing images with the Image Compressor tool before converting produces significantly smaller PDFs without noticeable quality loss.



• Choose appropriate page dimensions: For document scanning purposes, matching page size to the image dimensions gives the most authentic result. For print use, fit images to standard paper sizes (A4 or Letter) with appropriate margins.



• Consider OCR for text documents: If your images contain text (scanned documents, receipts, handwritten notes), converting to PDF only creates a raster PDF. For searchable, selectable text, run the PDF through an OCR service afterward.



• Use consistent resolution: When combining multiple images from different sources, images with very different resolutions will appear at different sizes unless scaled consistently. Resize images to consistent dimensions before combining.
