How to Batch Convert Images to PDF in 2026

Published on February 18, 2026 · 5 min read

Need to convert 50, 100, or even 500 images to PDF at once? Batch conversion saves hours of manual work. This guide shows you the fastest ways to convert multiple images to PDF simultaneously — for free, without any software installation.

What is Batch Image to PDF Conversion?

Batch conversion means converting multiple image files to PDF in a single operation instead of one by one. Instead of uploading and converting each image separately, you select all your images at once and get one or multiple PDFs in seconds.

  • Time saving: Convert 100 images in the same time it takes to convert 1
  • Consistent output: All PDFs use the same settings (page size, margins, orientation)
  • Merge or separate: Combine all images into one PDF, or create individual PDFs per image
  • Any format: Mix JPG, PNG, WEBP, and GIF files in the same batch

Method 1: Free Online Batch Converter (Recommended)

The fastest method — no software, no signup, works on any device.

Step 1: Upload All Your Images at Once

Go to imagetopdf.space and click "Select Images". In the file picker, press Ctrl+A (Windows) or Cmd+A (Mac) to select all images in a folder, or hold Ctrl/Cmd and click to select specific files.

Pro Tip: You can also drag and drop an entire folder of images directly onto the upload area. Supports JPG, PNG, WEBP, GIF, and HEIC formats.

Step 2: Arrange and Configure

After uploading, drag images to reorder them. Choose your settings:

  • Merge all into one PDF — perfect for photo albums, reports, portfolios
  • Individual PDFs — one PDF per image, downloaded as a ZIP
  • Page size: A4, Letter, Legal, A3, A5
  • Orientation: Portrait or Landscape
  • Margins: None, Small, or Large

Step 3: Convert and Download

Click "Convert to PDF". All processing happens in your browser — no upload to any server. Your PDF(s) download instantly. For large batches, the conversion still takes only a few seconds.

Method 2: Using Windows (Microsoft Print to PDF)

  1. Select all your images in File Explorer (Ctrl+A)
  2. Right-click → Print
  3. Select "Microsoft Print to PDF" as the printer
  4. Choose layout and click Print
  5. Name your file and save

Limitation: Windows creates one page per image but the layout options are very limited compared to online tools.

Method 3: Using Mac Preview

  1. Select all images in Finder (Cmd+A)
  2. Right-click → Open With → Preview
  3. In Preview, go to File → Print
  4. Click PDF → Save as PDF

Limitation: Preview doesn't let you control page size or margins easily, and the order depends on filename sorting.

Best Practices for Batch Conversion

Name Files in Order

Name your images 001.jpg, 002.jpg, 003.jpg so they sort correctly when uploaded. This ensures the PDF pages are in the right order.

Use Consistent Image Sizes

For the cleanest PDF, use images with the same aspect ratio. Mixed portrait and landscape images can look inconsistent in a single PDF.

Choose the Right Page Size

A4 is standard for documents. Use "No margin" setting to make images fill the entire page for photo albums.

Preview Before Downloading

Use the "Preview PDF" button to check the result before downloading, especially for large batches.
