Extracting embedded images from a PDF

1

While we already know how to edit existing PDF files in Ubuntu, there are times when the requirement is to use all or some of the images contained in a PDF file. Manual copy-pasting is definitely an option, but it’s not a time-saving one, especially when the PDF file contains a large number of images.

A tool exists, dubbed PDFImages, that makes image extraction from PDF files a cakewalk. In this article we will discuss this tool using easy-to-understand examples. Note that all the examples used in the article are tested on Ubuntu 14.04 LTS using version 0.24.5 of the tool.

As already discussed, PDFImages is a command line tool that you can use to extract images from a PDF file. The tool’s man page says that it reads the input PDF file, scans it, and produces one Portable Pixmap (PPM), Portable Pixmap (PBM), or JPEG file for each image it encounters in the PDF file.

If the tool isn’t already installed on your Ubuntu box, you can download and install it using the...

I often use Inkscape for this. Load the page, and delete all the other stuff. The advantage is that you can get vector images in SVG and modify them as you choose.

With the Adobe Acrobat PDF Optimizer, you can reduce the file size of a PDF in a number of ways. For example, you can compress images, flatten PDF layers, remove document data and unembed fonts. When a font is embedded in a PDF, the exact font formatting is always used in the PDF. When you remove an embedded font, a substitute font is used for the PDF if the font is not installed on a computer on which the PDF is viewed. You can remove embedded font for Roman text and East Asian text.

Unembed Fonts

Step 1

Open the PDF in Adobe Acrobat, click "Advanced" and choose "PDF Optimizer."

Step 2

Click the "Fonts" check box in the left pane.

Step 3

Select the font you want to remove from the "Embedded fonts" pane. You can select multiple fonts by pressing down the "Ctrl" key as you select multiple fonts.

Step 4

Click "Unembed" and click "OK."

Step 5

Provide a name for the file, select where you...

The official PDF file format specification (published by Adobe) is large and complex. PDF files can be rich, dynamic documents, and getting to all of the interesting and useful parts of them (i.e. their content, text, metadata, etc) is a daunting task.

Further, Adobe's specification only provides normative descriptions of how PDF documents should be constructed. Experience shows that applications must often process PDF documents from multiple sources, each of which may (and do) generate PDF files that sometimes bend and often break the "official" PDF specification — similar to how web browsers are forced to support broken and malformed HTML documents as best as they can.

This is just one of the many reasons why continually supporting and maintaining PDFxStream is a never-ending task. Doing anything else would prevent us from guaranteeing maximum compatibility with all PDF document formats and variants...

Say someone sent you a Word document with a lot of images, and you want you to save those images on your hard drive. You can extract images from a Microsoft Office document with a simple trick.

If you have a Word (.docx), Excel (.xlsx), or PowerPoint (.pptx) file with images or other files embedded, you can extract them (as well as the document’s text), without having to save each one separately. And best of all, you don’t need any extra software. The Office XML based file formats–docx, xlsx, and pptx–are actually compressed archives that you can open like any normal .zip file with Windows. From there, you can extract images, text, and other embedded files. You can use Windows’ built-in .zip support, or an app like 7-Zip if you prefer.

If you need to extract files from an older office document–like a .doc, .xls, or .ppt file–you can do so with a small piece of free software. We’ll detail that process at the end of this guide.
