How to Merge JPG / JPEGs to one File

Have you had a challenge in getting pictures into one document, or to upload a document online and you are required to get it as one document? You need to merge it into one JPEG, PDF or Word as DOC/DOCX. Also, I will teach you how to do it in Windows 10 and in Mac OS X.

The easier is using Microsoft Word;  set margins to 0", cut and past each jpeg to a page, save as pdf.  not pretty but works.

OR, you can copy the images from MS Word to Paint and save.

Using Windows 10, Select them in the Finder, open them all in Preview, and then Export As PDF.

Using Use Automator. The first action should be "Ask for Finder items", followed by the "Combine images into PDF" action.

Also, to combine multiple JPEG format image to one JPEG/PDF, various techniques and technologies are available. It varies for windows and MAC OS X. Here, we are talking about MAC OS X. Several free and paid apps are available to do this task, but in MAC OS X the preview app can do it for free without any hassle.

Here are the steps to save multiple JPEGs into one JPEG/PDF on Mac OS

Step 1: Select all of the images you want in your PDF, right-click and choose open with Preview

Step 2: In Preview's Sidebar drag the images into the order you want them to appear in your PDF

Step 3: Select/highlight all the images to be included in the PDF document; otherwise only a single image may end up the PDF document

Step 4: Then from the "File" menu choose "Print Selected Images" (or "Print..." in recent OS X versions) and then "PDF > Save as PDF"

Another option is either:

1. Open the first image file in Preview then save it as a PDF. Open the side bar in Preview and you will see a thumbnail of that first image. Then drag and drop all other image files on top of that thumbnail, the icon will change to a multi-page document icon. Save the PDF file.
2. Download and install Imagemagick, for free. Open the Terminal and change to the folder containing your image files. Suppose the images are named in sequence, e.g. scan01.jpg, scan02.jpg, and so on. Then enter the following command: convert scan*.jpg output.pdf. That's it. This method is very fast and convenient, and it often produces smaller PDF files than Preview.

If you are a programmer, you can use MatLab/ R.
Here are some STEPS in MATLAB for combining images adjacent to each other:

1. Check the size of all the jpegs (images). You can use size function here. example: "A" is an image with size 100 x 100 x 3 and "B" is an image with size 50 x 50 x 3.
2. You may now initialize another Matrix variable C with an aggregate of columns from image A and image B and maximum of(row(A),row(B)) from both the images. In our case it would be 100 x 150 x 3. To initiate a variable in MATLAB use C=zeros(100,150,3). Note argument "100" is the maximum #of rows between Image A and Image B, whereas "150" is the sum of columns from Image A and Image B.
3. Use a loop to pull out the values from A and B and put them together in C. For this you need nested looping and few "if" conditions.
4. Once you get the pixel values in C. Save it as jpeg on disk.

Another way was using Microsoft Powerpoint, paste them into PowerPoint, group them, right-click/ctrl-click and "save as picture".


That's how to quickly create a pdf  from multiple photos using Preview app
Step 1 :
Go to the folder containing multiple photos and Select All (Command + A)

Step 2 : Double Click -> Open with Preview. You can change the order of photos just by dragging the thumbnails

Step 3 : Go to file -> Print (Command+P) 

Step 4 : Pdf ->Save as Pdf  -> Select Destination -> Save

You can change orientation and margins according to your convenience....Enjoy your pdf.
