How to Combine Multiple Images Into One PDF

The Fastest Method: JPG to PDF Tool

Our JPG to PDF tool converts multiple images to a PDF in one step:

1. Open JPG to PDF
2. Upload all your images at once (JPG, PNG, or both)
3. Drag to put them in the correct page order
4. Click Convert
5. Download the multi-page PDF

Each image becomes one page in the output PDF. 10 images = 10 pages.

If Your Images Are Different Types

If you have a mix of JPG and PNG files, they can all be uploaded together to the JPG to PDF tool — it accepts both formats.

Step-by-Step for Large Batches

For more than 20 images, this workflow is most reliable:

1. Name all images sequentially before uploading: page-01.jpg, page-02.jpg, etc.
2. Upload to JPG to PDF
3. The tool sorts by filename by default — sequential naming means the order is already correct
4. Download and verify the page count

Managing File Size

The resulting PDF will be approximately the total size of all source images. If it is too large:

1. Run the PDF through Compress PDF with Medium compression
2. For submission portals with tight limits, use High compression
3. If still too large, use Split PDF to break it into sections

Combining With Other PDFs

If you also have existing PDF files and want to combine everything into one document:

1. Convert your image groups to PDF first (using JPG to PDF)
2. Then combine all PDFs using Merge PDF

This gives you full control over page order across different source formats.
