How to Convert JPEG Images to PDF

Turn a JPEG into a PDF with tools already on your computer or phone. Covers page size, fit, multiple images, and checking the output.

Changing a JPEG to a PDF is usually a print or export job, not a true conversion. Your system places the image on a PDF page, and the original file stays as it was. The steps below use tools that ship with common operating systems. Labels and layouts change between versions, so if a button reads slightly differently on your device, look for the closest equivalent.

Before you start

  • Keep a copy of the original JPEG. Most methods create a new PDF and leave the source alone, but a backup costs nothing.
  • Decide on the page layout. Choose whether you need one image per page or several images in one PDF, and whether the page should match a paper size such as A4 or Letter or follow the image's own shape.
  • Check the image's pixel dimensions and aspect ratio. A wide landscape photo on a portrait page will either shrink to fit or get cropped, depending on the setting you choose.
  • Know where the processing happens. Built-in print-to-PDF and export features on Windows, macOS, iOS and Android work on the device itself. Websites and some third-party apps upload your file to a remote server. For anything private, such as ID scans, receipts or personal photos, read the service's own statement on storage and deletion before uploading. Don't assume the file is removed automatically.

Step-by-step instructions

Windows: Microsoft Print to PDF

  • 1. Open the JPEG in the Photos app or another image viewer that can print.
  • 2. Open the Print dialog, either from the app's menu or with Ctrl+P.
  • 3. Choose Microsoft Print to PDF as the printer.
  • 4. Set orientation, paper size and the fit option. A fit option keeps the whole image visible, while a fill or crop option covers the page but can trim the edges.
  • 5. Select Print, then choose a name and folder for the new PDF when prompted.
  • 6. For several images, select them all in File Explorer, right-click, and choose Print if your Windows version offers it. You can then pick a layout and send the whole set to Microsoft Print to PDF as one file.

macOS: Preview

  • 1. Open the JPEG in Preview.
  • 2. Choose File, then Export as PDF, and save the new file.
  • 3. To combine several images, open them together in Preview and show the sidebar thumbnails. Arrange them in the order you want, then select them all and use the print dialog's PDF option to save a single document.
  • 4. If you need a specific paper size or margins, use File, then Print, set the options there, and choose to save as PDF from the PDF menu in the print dialog.

iPhone and iPad

  • 1. Open the photo, or select several photos, in the Photos app and tap the Share button.
  • 2. Choose Print.
  • 3. In the print preview, use the share option to save or send the result as a PDF, for example to the Files app. On some iOS versions you get the PDF by spreading two fingers apart on the preview thumbnail.
  • 4. Some versions also offer a direct PDF option in the share sheet. If yours does, you can skip the print preview step.

Android

  • 1. Open the image in your gallery or photo app and look for Print in the share or overflow menu.
  • 2. In the print screen, change the printer to Save as PDF.
  • 3. Adjust paper size and orientation, then tap the download or PDF button and choose where to save.
  • 4. Menu names vary by manufacturer and app. If you can't find Print, try opening the image in a different app that supports it.

Check the output

  • Open the PDF in a separate viewer and confirm the page count and image order.
  • Zoom in on fine detail such as text in a scanned document. If it looks softer than the original, the tool may have downscaled or re-compressed the image.
  • Compare file sizes. A PDF that is much smaller than the JPEG suggests extra compression was applied. One that is noticeably larger may contain added page data or a re-encoded image.
  • Check the edges for cropping and confirm the orientation. Photos taken with a rotated phone sometimes come out sideways if the rotation is stored only as metadata.
  • Remember that a JPEG has no transparency, so a PDF made from it will not have a transparent background either. Text inside the image stays an image. It is not searchable or selectable unless you run optical character recognition separately.

Common problems and next steps

  • Image is cut off: switch the scaling option from fill to fit, or change the page orientation to match the photo.
  • White borders around the photo: these are page margins. Choose a borderless or zero-margin option if your dialog offers one, or accept a small border for printing.
  • PDF is too large to email or upload: reduce the image's pixel dimensions before converting, or use a PDF tool with a compression setting. Check the result for quality loss afterward.
  • Pages are in the wrong order: rename the files so they sort correctly, or reorder the thumbnails before saving.
  • No print-to-PDF option appears: on Windows, check that Microsoft Print to PDF is enabled among the optional features. On other devices, try a different app that has a print function.
  • You need an editable document: converting a JPEG to PDF does not change the file format of the content inside, and the page remains a picture. Use a scanning or OCR tool if you need selectable text.
