How to Combine Images into One PDF (JPG, PNG, Any Format)

You have ten photos of receipts, five scanned pages, or a set of screenshots that need to become a single document. Sending them as individual image files is messy — some get lost, the order gets scrambled, and the recipient has to open each one separately.

Combining images into one PDF gives you a single, ordered file that opens identically on every device. Here is how to do it in your browser in seconds.

Combine images into a PDF in three steps

1. 1Open the JPG to PDF tool in your browser.
2. 2Drag in all your images. They can be JPG, PNG, or a mix of formats.
3. 3Arrange them in the order you want. The first image becomes page one.
4. 4Click Convert. The result is a multi-page PDF with one image per page.

The conversion runs entirely in your browser — no files are uploaded to any server. The original image quality is preserved because the image data is embedded into the PDF without re-encoding.

How to order the images correctly

The order you add images is the order they appear as pages. If your images are named with numbers — scan_01.jpg, scan_02.jpg, and so on — sort them by name before uploading. Most file browsers let you sort by name with a single click.

If you need to rearrange after adding them, drag and drop the thumbnails within the tool to set the correct page order before converting.

Page size and orientation

By default, each image is fitted to a standard page size — usually A4 or US Letter. This means:

• Landscape images get landscape pages automatically
• Portrait images get portrait pages
• Images that do not match the page ratio get white borders
• Very small images may appear centered with large white margins

If you need the PDF page to exactly match the pixel dimensions of your image — for example, when printing a photograph at its native aspect ratio — check for an option to use image dimensions as the page size.

Combining images on iPhone or Android

The browser-based tool works on mobile devices. Open it in Safari or Chrome, select images from your camera roll or file manager, arrange them, and download the PDF. The process is identical to desktop.

On iPhone, you can select multiple photos directly from the Photos app. On Android, select multiple images from your gallery or file manager.

When to use PDF instead of sending images directly

• When you need images in a specific order — PDFs enforce page sequence
• When submitting to a form or portal that requires PDF
• When printing — a PDF with images prints as a document, not as separate files
• When archiving — a single PDF is easier to store and search than dozens of image files
• When emailing — one attachment is cleaner than twenty

PDF file size after combining images

The resulting PDF is approximately the sum of all the individual image files, plus a small amount of PDF overhead. If the combined file is too large, compress it after combining to reduce size without losing visible quality.
