How to insert image in PDF on computer

If you need to insert an image in PDF on a computer, my advice is to rely on LibreOffice: if you have never heard of it, it is a complete, open-source and free office suite, available for Windows, macOS and Linux, which includes a series of programs used to create and modify documents of various types. As for PDF documents, the component of the suite to rely on to edit them is LibreOffice Draw.

How to insert image in PDF on Windows

To download and install LibreOffice on Windows, connected to the suite home page, click on the Download xyz version button and wait for the software installation package to be copied to your computer. When the download is complete, start the file obtained and follow the wizard that appears on the screen: click on the Next button, put the checkmark next to the item  Typical, if not already there, press the Next button again and complete the setup, click on  Install,  Yes and  Finish.

After completing the installation of LibreOffice, start the program, click on the Open file button located in the left sidebar and, using the File Explorer window, choose the PDF document to act on. Within a few seconds, Draw should automatically open.

Now, to insert an image into the document, click on the Insert> Image … menu (in alo), choose the photo to include in the document, using the next screen and, having made your selection, drag it to the exact point where you want to insert it using the mouse.

If needed, you can change its size using the indicators that appear on the edges and act on parameters such as the level of transparency, the alignment of the text and other details of this type using the functions available in the right sidebar.

Unlike Word files, where text automatically adapts to images, in PDFs edited with LibreOffice you have to manually set the position and arrangement of the text; in fact, each line is treated as a separate block of text.

To work around this problem, move or resize the text blocks with the mouse (you can also select multiple blocks at the same time), change the font size or just go back and forth. It is not very comfortable, I know, but with a little practice I assure you that you can get excellent results.

At the end of the changes, to save your document in PDF format, click on the disk icon located at the top left (the white sheet with the red Adobe Reader logo) and choose the folder in which to export the file.

How to insert image into PDF Mac

The procedure to install LibreOffice on macOS is slightly longer than the one seen for Windows, since, in addition to the actual program, it is necessary to install the Italian translation package.

In any case, to proceed, connected to this website, click first on the  Download the xyz version button and then on the Translated user interface button, in order to download both the necessary files.

When the download is complete, launch the first downloaded file (eg  LibreOffice_xx_MacOS_x86-64.dmg ) and, using the window that appears on the screen, drag the LibreOffice icon to the Applications folder on the Mac. Then, access this folder, right-click on the icon you just copied and press  Open twice in a row, in order to overcome the restrictions imposed by Apple on non-certified developers.

After starting the program for the first time (and consequently creating the related folders and configuration files), close its main window by pressing the combination of keys cmd + q or by going to the LibreOffice menu  > Exit LibreOffice.

Then start the package containing the translated interface downloaded just now (eg LibreOffice_xx_MacOS_x86_64_langpack_it.dmg ), right-click on the executable you find inside and press Open twice to start it. At this point, click on the Install button, put the checkmark next to the item  / Applications / from the window that opens, click again on the Install button and, if necessary, click on Yes, identify me and type the password of the your user account on macOS, to install the language pack. If everything went well, you should have translated the LibreOffice interface into Italian.

Finally we are there: once the translation of the program is completed, start it, click on the Open file … button located in the left sidebar, choose the PDF document on which to act through the Finder window and wait for the Draw program to open the chosen file. From this moment on, you can proceed in an almost identical way to what we saw for Windows, as the interface is practically the same.

How to insert image in PDF online

If you don’t feel like installing new programs on your PC, you can insert image into PDF  using  PDFEscape, a free online service that allows you to edit PDF files directly in your browser. It works with all the most popular navigation programs, does not require registration and allows you to process any document with a maximum number of 100 pages and/or a maximum weight of 10MB.

To find out how it works, linked to its home page, click on  Upload PDF to PDFescape and drag the PDF to be edited into the browser window, or click on the Choose file button to select it manually.

Now, select the page where you want to insert the image, click on the Image button located in the left sidebar and drag the photo to add to the PDF in the box that opens or insert it manually using the Choose file button.
