1. Using Google Drive

Google Drive is the safest option to convert multiple images into a single PDF file on Android as it comes pre-installed on almost all Android phones. The drawback of this method is that you must capture new photos and convert those into PDF documents. You cannot use existing images and convert them into PDFs.

  1. Open the Google Drive app on your phone.
  2. Tap on the floating (+) add icon and select Scan from the menu.
  3. The Camera interface will open. Point the Camera towards the picture and hit the Capture button.
  4. If you are happy with the photo, tap on the Checkmark icon.
  5. You will get many editing and formatting options on the next screen. Here’s what each icon means:

Back Icon: Tap on this icon to discard the photo and capture a new photo.Color Palette: Use this icon to select the color mode for the photo, such as black and white, color, color drawing, or none.Rotate: This icon lets you rotate the captured image.Crop: Use the crop icon to crop the captured image.

Tap on the Add (+) icon to capture more photos for your PDF file. 6. Once you capture other photos, swipe right or left on the screen to view all the photos. You can edit them individually using the options mentioned in step 5. If you want to remove any photo, tap on the (-) Remove icon at the bottom. 7. When all your images are finalized, tap on the Save button. Name your PDF file and select the Google Drive account and folder to save the PDF file. Hit the Save button. 8. The PDF file will start uploading to Google Drive. If you want to download the PDF file to your Android phone, open the Google Drive app and go to the folder where you saved the PDF file. 9. Tap on the three-dot icon next to the PDF file and select Download. The downloaded PDF file will show up in the Downloads folder of your phone. Tip: Learn how to free up space in Google Drive.

2. Using Microsoft Lens

If you want to create a PDF file from multiple images present in your phone’s gallery, you should use the Microsoft Lens app. It lets you create PDF files both from the existing images as well as from Camera.

  5. You can then add more images, apply a filter to the image, crop, rotate, reorder, or add text to images. Finally, hit the Done button.
  6. Give a name to your PDF file and select the box next to PDF. Also, tap on the arrow next to the PDF option and choose save location from Phone storage or OneDrive. Lastly, tap on the Save button to download the PDF file.
