JPG to PDF

About the JPG to PDF Converter

The JPG to PDF Converter is a free online tool that allows you to combine one or more images into a single PDF document directly in your browser.
Whether you need to compile photographs into a portfolio, convert scanned documents into a shareable PDF, or package multiple images for printing, this tool handles the entire process without uploading your files to any server.

Supporting both JPEG and PNG image formats, the converter gives you full control over page sizing, image ordering, and layout. The generated PDF preserves your original image quality while providing a universally compatible document format.

Key Features

• Multiple Image Support:
  Upload and combine as many JPG and PNG images as you need into a single PDF document. Add more images at any time before generating the final file.
• Drag-and-Drop Reordering:
  Rearrange the order of your images by simply dragging and dropping thumbnails. The final PDF will follow the exact order you set.
• Flexible Page Sizes:
  Choose from multiple page size options including Fit to Image (which matches each page exactly to the image dimensions) and standard paper sizes from A1 through A10.
• Smart Image Scaling:
  When using a fixed page size, images are automatically scaled down to fit within the page boundaries while maintaining their original aspect ratio. Smaller images are centered on the page without being stretched.
• Image Deletion:
  Remove individual images from the queue before generating the PDF, giving you precise control over the final document contents.
• Client-Side Processing:
  The entire conversion process runs in your browser using the pdf-lib library. Your images are never uploaded to any server, ensuring complete privacy and data security.
• Instant Download:
  Once the PDF is generated, it downloads automatically to your device without any waiting or additional steps.

How to Use the JPG to PDF Converter

1. Upload Images:
   Drag and drop your JPG or PNG files into the upload area, or click to browse and select files from your device. You can upload multiple images at once.
2. Arrange the Order:
   Review the uploaded image thumbnails and drag them into your preferred order. The first image will become the first page of the PDF.
3. Select Page Size:
   Choose a page size from the dropdown menu. Select "Fit to Image" to match each page to its image dimensions, or pick a standard paper size like A4 for uniform pages.
4. Add or Remove Images:
   Use the "Add More Images" button to include additional files, or click the delete button on any thumbnail to remove it from the queue.
5. Generate PDF:
   Click the "Generate PDF" button to create and download your PDF document.

Best Practices

• Use High-Resolution Images:
  For the best results when printing, use images with a resolution of at least 300 DPI. The converter preserves your original image quality in the output PDF.
• Choose the Right Page Size:
  Use "Fit to Image" when you want each page to match its image exactly, which is ideal for digital viewing. Select a standard paper size like A4 when you plan to print the PDF.
• Organize Before Converting:
  While you can reorder images after uploading, it helps to name or number your files beforehand so you can quickly identify them in the thumbnail grid.
• Check Image Orientation:
  Ensure your images are oriented correctly before uploading. The converter places each image as-is onto its respective PDF page.
• Use PNG for Transparency:
  If your images contain transparent areas, upload them as PNG files. JPEG files do not support transparency and will display a white background.

Common Use Cases

• Document Scanning:
  Compile scanned pages or photographs of documents into a single, organized PDF file for archiving or sharing.
• Photo Portfolios:
  Create professional-looking PDF portfolios by combining your best photographs into a single document.
• Receipts and Invoices:
  Consolidate photographs of receipts, invoices, or other paperwork into a single PDF for expense reporting or record keeping.
• Presentations and Reports:
  Convert image-based slides, charts, or diagrams into a distributable PDF format.
• Print Preparation:
  Package images with specific page sizes for professional printing or submission to print services.
