How to Convert Image to PDF with Traditional Scanner
If the document or image you want to convert is not yet scanned, you can use your scanning machine to scan the file and save it as an image-based PDF. Nevertheless, if you don’t have a traditional scanner, there are other ways to scan your file. For instance, you can manually photograph the document using your smartphone’s back camera. However, using a camera will only let you save the image to JPEG or PNG format. So, suppose you want to know how to scan multiple images to PDF. In that case, we have created a basic tutorial on doing it with a traditional scanning machine. Of course, a conventional scanner is still best, especially in the digital industry. Still, the process will depend on the machine model you are using. Check the guide to edit scanned PDF or images and convert it afterward to searchable PDFs using a scanner.
User Guide:
- First, ensure your scanning machine is plugged in and turned “ON.” Then, clean the “scanner bed” and put the image or document face-down. After that, open the scanning software that comes with your scanner. Next, set the scan to “PDF” format and select your preferred scan resolution.
- If the software of your machine support adjusting the image settings, modify it quickly. You can change the brightness, saturation, quality, and contrast. Then, preview the file to make sure that it is properly aligned. You can crop the image depending on your requirement to remove unwanted borders.
