How to Convert Images to PDF

When converting images to PDF makes sense

Images and PDFs serve different purposes. An image stays an image — it has no concept of pages, no consistent print dimensions, and opens differently in different apps. A PDF is a document: pages, consistent layout, predictable behavior when printed or shared.

Converting to PDF is useful when:

• You photographed paper documents and need to share them as a proper file
• An online form requires a PDF but you only have a JPG
• You want to combine multiple images into one document instead of sending several files
• You need a portable version of a screenshot or diagram with consistent page dimensions

Supported image formats

PDFDistrict’s Image to PDF tool accepts JPG, PNG, and WebP files, along with other common image formats. Each image becomes one page in the resulting PDF.

The original image is not modified. The PDF is created as a new file, and your image files remain unchanged on your device.

How to convert images to PDF

1. 1 Open the Image to PDF tool at pdfdistrict.com/img-to-pdf/ and click “Select Images to Convert.”
2. 2 Add your images — drag and drop them onto the tool or click to browse. You can add multiple images at once; each will become a separate page in the PDF.
3. 3 Choose a page size: Fit to image (the page matches the image dimensions exactly), A4, or US Letter. Then click “Convert to PDF.” The PDF downloads instantly.

Choosing the right page size

The page size option determines how the image is framed on each page of the PDF.

• Fit to image — the page dimensions match the image. Good for digital-only sharing where print margins don’t matter.
• A4 — standard European/international document size (210×297 mm). Use this if the PDF may be printed or shared in a professional context.
• US Letter — standard North American size (8.5×11 in). Use this for documents destined for a US audience.

Whichever page size you choose, the aspect ratio of your images is always preserved. The image is centered within the page; no cropping occurs.

Converting multiple images at once

You can add as many images as you need in one go. Each image becomes one page, in the order you added them. The result is a single multi-page PDF containing all your images.

This is useful when you’ve scanned a multi-page paper document as separate JPEG files, or photographed each page of a form individually.

What to do with the PDF after converting

Once you have the PDF, you can work with it like any other PDF file. If you need to combine it with other existing PDFs — for example, adding a photo of a signed signature page to a contract — the Merge tool lets you combine them into one document.
