![]() If no output is specified, the output will go to stdout. Printf modifiers are supported, for example "d". Embed %d in the name to indicate the page number (for example: "page%d.png"). The output format is inferred from the output filename. Use the specified password if the file is encrypted. The supported output text formats are: plain text, html, and structured text (as xml). The supported output vector formats are: svg, pdf, and debug trace (as xml). The supported output image formats are: pbm, pgm, ppm, pam, png, pwg, pcl and ps. The supported input document formats are: pdf, xps, cbz, and epub. The draw command will render a document to image files, convert to another vector format, or extract the text content. There are several sub commands available, as described below. Mutool is a tool based on MuPDF for dealing with document files in various manners. Print the outline (table of contents) of a PDF: mutool show input.pdf outline.Extract all images, fonts and resources embedded in a PDF out into the current directory: mutool extract input.pdf.Query information about all content embedded in a PDF: mutool info input.pdf.Concatenate two PDFs: mutool merge -o output.pdf input1.pdf input2.pdf.Convert pages 2, 3 and 5 of a PDF into text in the standard output: mutool draw -F txt file.pdf 2,3,5.Convert pages 1-10 into 10 PNGs: mutool convert -o image%d.png file.pdf 1-10.Learn also: How to Extract Images from PDF in Linux.All purpose tool for dealing with PDF files Examples (TL DR) In this tutorial, we have passed by some methods to do that.įor me, I would go for the pdftotext option we showed as the first choice in this tutorial, good luck with your project! Windows has many software solutions for such cases, but Linux has a more robust command shell. While manually extracting some links from a pdf file is easy to do, the issue becomes more complex when the pdf file has hundreds of pages or multiple documents. You can also use it as a Python library or in a bash script. There are many options to use, such as the -v flag for having all references, not just the PDFs, and -t flag to extract the pdf text, and -c flag to detect the broken links. Now let’s use the previous command on this PDF document: $ pdfx -v | sed -n 's/^- \(http\)/\1/p' To use it, simply pass the PDF path on your machine or the remote URL of the PDF document, as it’ll automatically download it: $ pdfx If you already have Python installed, you simply use easy_install to install it: $ sudo easy_install -U pdfx Pdfx has many features and options that deserve to try, such as finding broken hyperlinks (using the -c flag), outputting the result as JSON, and online pdf files directly without downloading them. But you need to install it firstly with easy_install or pip, or you will get a “command not found” message: $ pdfx -v file.pdf | sed -n 's/^- \(http\)/\1/p' ![]() Using pdfxĪnother alternative would be pdfx. However, as you can see, we will miss many URLs the first method is the preferred one. You can also use the pre-built strings command and grep to do the same thing: $ strings somePDFfile.pdf | grep http Related: How to Convert PDF Files to Images in Linux Using Strings If you want to test the above command but don’t have an example PDF document, you can download a sample here. You still need to merge it with some options and other commands such as grep, like this: $ pdftotext -raw "filename.pdf"
