How to extract image from PDF file

Question

I currently use Foxit's PDF reader, and I recently downloaded an image from the Internet, but it is inside a PDF file. How do I extract this image?

Operating system is Windows 7.

your highest quality extraction will be to extract to whatever format the image is already stored in within the pdf. (at least i think that's how images-in-pdfs work.) — quack quixote, Apr 26 '10 at 17:06
I note not a single answer exists where you use an "easy" copy paste to retain a transparent background. All answers so far that functions are batch or command based. — CapnZapp, Dec 26 '19 at 13:59

If you download XPDF for Windows (here), you'll find a few .exe files inside. You can run them without "installation". Use pdfimages.exe like this:

pdfimages.exe -help

This displays the help screen.

pdfimages.exe ^
    -j ^
    c:\path\to\your.pdf ^
    c:\path\to\where\you\want\images\prefix\

This extracts all JPEGs as prefix-00N.jpg, and all the other images as prefix-00N.ppm (Portable PixMap).

[Edit by ComFreek: Please note the trailing slash in the destination path, which is important if you do not want to extract all images into its parent directory.] --
{Edit by KurtPfeifle: I do not agree with ComFreek's comment, but leave it to the readers to test and find out the differences in results themselves. My original parameter, not using a trailing slash, as ..\prefix will prefix the image names used for the extracted files.}

pdfimages.exe ^
    -j ^
    -f 11 ^
    -l 13 ^
    c:\path\to\your.pdf ^
    c:\path\to\where\you\want\images\prefix\

Same as before, but limits image extraction to pages 11 ('f' = first) to 13 ('l' = last).

Update:

In the meanwhile I prefer Poppler's version of pdfimages -- especially since it acquired this new feature: add -list to the commandline in order to just list (not extract) images contained in the PDF, plus some of their properties. Example:

pdfimages -list -f 7 -l 8  ct-magazin-14-2012.pdf

     8    14 image     344   364  gray    1   8  jpx    no      2079  0

Note again: this version of pdfimages is the one from Poppler (the one from XPDF does not (yet?) support this new feature), and the version must be v0.20.2 or newer.

The point of "This extracts all JPEGs ... and all the other images as Portable PixMap .PPM" is important. Sometimes you want a tool that can convert everything to one format – Ron Harlev Jun 23 '11 at 18:25
@harlev: if you want everything as PPM, just leave away the `-j` from the commandline. – Kurt Pfeifle Jun 23 '11 at 21:06
I want all as JPG. Can this tool do that? – Ron Harlev Jun 23 '11 at 21:46
@harlev: If you want all as JPEG, you can convert the PPMs to JPEG anyway. Remember, not all embedded images have initially been JPEGs in the first place, and hence were not embedded as such... – Kurt Pfeifle Jun 23 '11 at 21:57
@pipitas Will this tool convert the PPM to JPG? If not, do you know a free easy tool that will? – Ron Harlev Jun 23 '11 at 22:45

@harlev: Google for *ImageMagick*. It has a commandline tool that can convert anything to anything called `convert`. Available for Linux, Windows, MacOS X and what have you. Easiest use case for you: `convert some.ppm some.jpeg`. – Kurt Pfeifle Jun 24 '11 at 00:15

Note: XPDF isn't as actively maintained as the [poppler library](http://poppler.freedesktop.org/) which forked from it some time ago. Poppler provides `pdfimages` as well, and some people might prefer using that. – MvG Jan 29 '13 at 12:54
@MvG: in fact, since about 2 years my preferred kind of `pdfimages` also is the Poppler one. I updated the answer accordingly. Thanks for the hint! – Kurt Pfeifle Feb 24 '13 at 17:21
@RonHarlev: You may also try using [XnView](http://www.xnview.com/en/xnview/) (or [XnViewMP](http://www.xnview.com/en/xnviewmp/), or [XnConvert](http://www.xnview.com/en/xnconvert/)) to convert from PPM to JPG. You may also use one of the many other image viewers/converters; but XnView is full-featured and is the one I've used most. – Denilson Sá Maia Apr 22 '13 at 05:11

You can try importing the PDF into Inkscape, and work from there. Inkscape will only open one page at time, but will give you complete control over the page contents. You will be able to extract and manipulate vector graphics from the PDF quite easily.

However, if you want to extract raster images from the PDF, I'm pretty sure pdfimages from XPDF is easier (but you can still try using Inkscape after learning how to extract embedded images from SVG files).

GIMP (http://gimp.org) is another graphic design tool that can import and manipulate PDFs. Not sure however how GIMPs capabilities contrast with those in Inkscape. – Nov 11 '15 at 16:09
@coderworks: GIMP will rasterize the imported PDF page into a given resolution. In other words, it is slightly better than using "Print Screen". Inkscape, on the other hand, will preserve the original vector data as well as the original raster images. – Denilson Sá Maia Nov 11 '15 at 22:50

Without installing any software, you can switch to PDF-XChange Viewer (select Portable Version) which has this ability already build-in

exports all or selected pages as image
output format: PNG, JPG, TIFF, BMP
choose DPI, compression level, gray-scale
can save multiple pages as multi-page TIFF

^{click to enlarge}

Please be aware while this method converts whole PDF pages into images, the method explained from @Laurenz using Sumatra PDF is superior if you want to extract images from a PDF page with mixed content (image + text) to only get the image.

@MarkSeemann I cannot follow. "Without installing any software" means in this context that there is a portable version available. Portable software could not be "installed" per definition. You just download, extract and start it. – nixda Nov 01 '15 at 11:41

The fact that you need to "Chose the DPI" defeats the purpose. You are resizing raster images (array of pixels), and any resize of a raster image results in a loss of quality and information. – anthony Oct 26 '16 at 23:54

The quick way if you don't require original pixel resolution of the image is to just press ALT and Print Screen buttons. Then choose paste where ever you want the image.

The other way to preserve the resolution is to open the PDF in an image editing program such as Adobe Photoshop and work with it there.

Opening a PDF document in Photoshop causes the 'Rasterize Generic PDF Format' dialog to appear, so the resolution cannot be preserved. Tested with PS7. Are newer versions of Photoshop different? – AffineMesh Apr 27 '10 at 06:55

as you said, [alt]+[prnscr] does not preserve the original pixel resolution (it uses whatever resolution your current screen/monitor uses). – Kurt Pfeifle Jul 29 '10 at 15:18

@studiohack, @UserSuUserDo: Not only will you miss the original resolution if you use [alt]+[prnscr], but you'll get the complete PDF viewer window as a picture. This may be 'good enough' for many use cases. But sometimes you want the graphic as is embedded in the PDF page only. Here `pdfimages.exe` comes in handy. – Kurt Pfeifle Jul 29 '10 at 15:21

Or use the snipping tool built into W7 to capture the area you want. – Moab Jul 29 '10 at 15:22

MuPDF is a new (created in 2006) multiplatform (desktop and mobile) PDF viewer released under AGPL license. It is maintained by the same people of Ghostscript.

It contains a command-line tool to extract images from a PDF:

mutool extract [options] file.pdf [object numbers]

The extract command can be used to extract images and font files from a PDF. If no object numbers are given on the command line, all images and fonts will be extracted.

-p password
       Use the specified password if the file is encrypted.

-r     Convert images to RGB when extracting them.

use pdftocairo from poppler toolkit. It can extract and convert images of pdf to any desired format. It always generate images and never generate ppm or some craps like that. Following command covert the pdf pages to jpg images of it:

pdftocairo.exe -jpeg "my.pdf" "my"

You can get it from here for windows: http://blog.alivate.com.au/poppler-windows/

It's available on Linux too.

With Affinity Publisher 1.9+ you can open the pdf, and then go to Document → Section Manager. Inside it, you select the image (or even all the embedded images with Ctrl a or a similar method, which is quite useful) and you click Collect.... It will ask for a folder, and after that you will find (all) the selected picture(s) inside it.

normally I extract the embedded image with 'pdfimages' at the native resolution, then use ImageMagick's convert to the needed format:

$ pdfimages -list fileName.pdf
$ pdfimages fileName.pdf fileName   # save in .ppm format
$ convert fileName-000.ppm fileName-000.png

this generate the best and smallest result file.

Note: For lossy JPG embedded images, you had to use -j:

$ pdfimages -j fileName.pdf fileName   # save in .jpg format

UPDATE: On recent "poppler-util" (0.50+, 2016), pdfimages has an option "-all" to extract lossless compressed bitmap as .png and lossy compressed bitmap as .jpg, so a simple:

$ pdfimages -all fileName.pdf fileName

extract always the best possible quality content from PDF.

On little provided Win platform you had to download a recent (0.68, 2018) 'poppler-util' binary from: http://blog.alivate.com.au/poppler-windows/
