How to Combine JPG Images into One PDF

When this is the right job

A few common situations where combining JPGs into one PDF is the right move:

• You photographed a multi page document and need to send it as one file
• You have a collection of receipts or invoices to file together
• You want to share a photo album in a format that opens on any device
• You need to submit images to a portal that only accepts PDFs

Email, government portals, and many job application sites prefer PDFs over loose images. One PDF is also easier for the recipient to scroll through than a folder of files.

The quick way

Open the Image to PDF tool, drop in your JPGs, drag them into the right order, and click create. Download the new PDF and you are done.

The whole process takes under a minute even for 20 or 30 images. Everything runs in your browser, so the images are not uploaded anywhere.

Step by step

1. Open the Image to PDF tool.
2. Drop your JPG files into the upload area, or click to select them. You can select multiple files at once.
3. Once they appear as thumbnails, drag to reorder. The order in the list is the page order in the final PDF.
4. Choose a page size. A4 works for most documents. Letter is common in the US. "Fit to image" preserves the original image dimensions.
5. Pick orientation if your page size is fixed (portrait or landscape).
6. Click Create PDF and download the result.

Picking the right page size

A4 and Letter are the safe defaults. Use them when the recipient will print the file or view it as a document.

"Fit to image" is useful when:

• The images are not standard document proportions
• You want zero white space around each image
• The PDF is for viewing on screen and printing does not matter

Mixing portrait and landscape images on fixed page sizes can result in some images being scaled down. If this is a problem, either rotate the images first or use "Fit to image" mode.

Quality and file size

The tool encodes images as JPEG inside the PDF, which is efficient but slightly lossy. For most photos this is invisible. For sharp documents or text scans, the difference is also usually unnoticeable.

If your source images are very large (5 MB or more each), the output PDF can become huge. Use the Compress Image tool first at 85 to 90 percent quality to bring file size down before creating the PDF.

A common gotcha with PNG transparency

If you mix PNG files with transparent backgrounds into the workflow, transparency is not preserved in the output. Transparent areas appear white in the PDF. This is a JPEG encoding limitation, not a tool bug.

If you need to preserve transparency, the workflow does not support that. Use a different output format or add a solid background to the PNGs before converting.

After creating the PDF

Common next steps:

• Add this PDF to a larger document with Merge PDF
• Add a password with Protect PDF before sharing sensitive content
• Remove your author name from the file properties using PDF Metadata

When to consider an alternative

If you only have one or two images and you need them in PDF form quickly, you can also print to PDF from your operating system's built in print dialog. The Image to PDF tool is better when you have multiple images, need control over order, or want a consistent page size across the document.
