Create a single pdf from multiple text, images or pdf files

Question

I have a bunch of text files, images and pdf files which I want to convert into a single pdf file. How do I do it?

Answer 1

If you're willing to use a terminal, you can use ImageMagick. Install it with

sudo apt install imagemagick

then you can do:

convert image1.jpg image2.png text.txt PDFfile.pdf outputFileName.pdf

or as another example:

convert *.jpg outputJpgFiles.pdf

It worked for me, but the problem is it converts the text.txt file into an image, so you can't highlight the text in the resulting pdf.

Answer 2

Install pdftk

sudo apt-get install pdftk

Pdftk

If PDF is electronic paper, then pdftk is an electronic staple-remover, hole-punch, binder, secret-decoder-ring, and X-Ray-glasses. Pdftk is a simple tool for doing everyday things with PDF documents.

You can create pdf files from text or images with Libre Office then to stitch these togeter with other pdf files

pdftk 1.pdf 2.pdf 3.pdf cat output 123.pdf

It can also

• Split PDF Pages into a New Document

• Rotate PDF Pages or Documents

and a lot more besides

Answer 3

Try PDF Chain:

PDF Chain is a graphical user interface for the PDF Toolkit (PDFtk). The GUI supports all common features of the command line tool in a comfortable way.

You can install it either from the default repos, or get the latest and greatest from PDF Chain PPA.

sudo apt-get install pdfchain

Or PDF Mod:

PDF Mod is a simple application for modifying PDF documents.

You can reorder, rotate, and remove pages, export images from a document, edit the title, subject, author, and keywords, and combine documents via drag and drop.

sudo apt-get install pdfmod

Answer 4

For multiple files inside a directory and its subdirectories with different extensions I couldn't find a neat answer, so here it is

convert -quality 85 `find -type f -name '*.png' -or -name '*.jpg' | sort -V` output.pdf

I used command substitution to pass the selected items returned by find command as an argument to convert command. Unfortunately sort -n didn't sort my files correctly so I tried -V option and it did the trick. Also make sure the name of your files and directories are in natural sort order in advance. For example dir1, dir2, dir3 not dir1, dir_2, dir3.

Answer 5

This is the solution i used to convert multiple TIFFs to PDFs.

I had to create more than 6.000 PDFs starting from 30.000 tiffs. convert estimate time: 6 to 7 hours.
I used tiffcp and tiff2pdf, they took few seconds.

$ tiffcp 1.tiff 2.tiff ... multi.tiff
$ tiff2pdf multi.tiff > final.pdf

This way is really fast because images are not converted, just packed.

Maybe there are some tiff formats that doesn't work so easily, for me it worked perfectly.

Hope it helps.

Answer 6

Install Master PDF editor. The tool offers creating, merging and extracting PDF files. Check here for details about master PDF editor and installing it on Ubuntu

Answer 7

I use PDF-Shuffler for this kind of use, it works great.

sudo apt-get install pdfshuffler

It is a graphical tool. You simply load all the pdf files you want to fuse. You can change the page order as you wish.

Answer 8

I can't believe nobody has mentioned latex (tex) yet. It is specifically designed for producing documents, and can combine text, images, and PDFs into a 'master' document (without any degradation of quality). It is a full suite of libraries and an extensible markup language, basically - it's been around since forever and highly used in the scientific community, still.

Technically, it's a typesetting language.

Answer 9

Try LaTeX with pdflatex.

I had never used it before but it took me about 10 minutes to start making .PDFs with it and about 40 minutes to get them customized exactly as I wanted. I included the best formatting guides I found, at the end.

sudo apt-get install pdflatex && sudo apt-get install texlive

Basically you create one .tex file - for example hello.tex - with the LaTeX language, then run pdflatex hello.tex on that file and it will generate the PDF. The basics of the language can be found here: http://www.maths.tcd.ie/~dwilkins/LaTeXPrimer/

Here is a barebones example .tex file:

 \documentclass[a4paper,10pt]{article}

 \begin{document}

 {\footnotesize
 YOUR TEXT HERE

 YOUR TEXT HERE
 }

 \end{document}

To change page size and margins when using pdflatex: \usepackage[pass,paperwidth=148mm,paperheight=210mm,margin=5mm]{geometry}

Answer 10

Adding on the community answer above, you can do convert 'ls *.jpg -tr'. To force the PDF file to have the images in chronological order.

Answer 11

There is series of utilities in package texlive-extra-utils wrapped on pdfjam. To join pdfs use

pdfjoin -o out.pdf 1.pdf 2.pdf 3.pdf

Unlike convert it directly manipulates on pdf without converting them to images.

Also on 18.04LTS (Bionic Beaver) at this moment package pdftk is not supported. I would recommend pdfjam if someone prefers to use command line.

Answer 12

Using Gimp, import as layers, export as pdf:)

Gimp version: 2.10.8

Answer 13

1. Images to PDF

A tool I wrote called pdf2searchablepdf can combine many images into a single PDF. It is particularly good if you want the final PDF to have searchable text in it, as my tool performs OCR (Optical Character Recognition) on the images using a program called tesseract in order to bundle them into a single PDF.

Installation instructions are here: https://github.com/ElectricRCAircraftGuy/PDF2SearchablePDF#install

Since pdf2searchablepdf is a wrapper around tesseract, it accepts any image format supported by tesseract, which includes bmp, pnm, png, jfif, jpeg/jpg, and tiff. Gif is not supported. See https://coptr.digipres.org/index.php/Tesseract-ocr:

Any image readable by Leptonica is supported in Tesseract including BMP, PNM, PNG, JFIF, JPEG, and TIFF. GIF is not supported http://www.leptonica.com/library-overview.html.

To convert all images into a PDF, they need to be all in the same folder and with nothing else in that folder. So, assuming you have img1.jpg, img2.jpg, and image3.jpg, you could do this:

# Create an `images` dir and move all images into it
mkdir -p images
mv *.jpg images  # use `cp` instead of `mv` to copy instead of move the images

# Now combine all of these images into 1 pdf
pdf2searchablepdf images

That's it! You'll now have a searchable PDF file called images_searchable.pdf in the directory you were in when you ran the pdf2searchablepdf command.

Note: to go the opposite direction and convert a PDF file into a bunch of image files, I like to use pdftoppm as I explain here.

To convert a non-searchable pdf named input.pdf into a searchable pdf named input_searchable.pdf, do:

pdf2searchablepdf input.pdf

See pdf2searchablepdf -h for the full help menu, including options and other examples.

Answer 14

For multi-page pdf:
Convert all files to pdf, then join using a pdf writer eg. pdftk, pdfill, Microsoft Print to PDF, CutePDF, etc

For single-page pdf:
Convert all files to images eg. PNG, named in sequence. Then join to one page with image converter eg. imgconv

imgconv.exe -append *.png out2.pdf (for vertical)
imgconv.exe +append *.png out2.pdf (for sideways)

if you're not on Win 10 WSL, load ImageMagick:

sudo apt-get install imagemagick

The converter, installed as part of imagemagick converts to one pdf:

convert "*.{png}" -quality 100 combined.pdf

If you already have single page pdfs, merge them with pdftk:

pdftk *.pdf cat output combined.pdf
