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?

20Well, you can do `convert image1.jpg image2.png text.txt PDFfile.pdf outputFileName.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. – Alaa Ali Jun 04 '13 at 08:46

4@Alaa you should post this as an answer rather than a comment. Simple, concise and on the money. – LAFK says Reinstate Monica Dec 14 '13 at 02:10

1gscan2pdf Is a GUI version also in case the command 'convert' fails and worked for me. (from ifoss.com): Once gscan2pdf is opened, you can select all the required files in it by clicking on the Open Files. By default it is arranged in alphabetical order but you can drag and drop to reorder the images as per your choice. then click on the Save icon to save the files to PDF. if you just want a PDF file, hit the save . Since by default the output file is PDF, you don’t need to bother a lot here. Just choose where to save the converted file. Save the converted images to pdf, That’s it. – Bran Sep 08 '14 at 00:05

@AlaaAli, you can take your resulting PDF and make it searchable again using my `pdf2searchablepdf` tool I wrote, [which I describe here](https://askubuntu.com/a/1385947/327339). It's a wrapper around the `tesseract` OCR engine. – Gabriel Staples Jan 08 '22 at 07:11

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.

5ImageMagic `convert` reduces quality and increases size in my experience. Try `pdftk`. But not sure how you add images there. – akostadinov Sep 22 '14 at 12:22
-
6You can tweak with `-quality` flag to increase or decrease the resulting PDF file size. Example: `convert -quality 50 image1.jpeg image2.jpeg image3.jpeg outputFileName.pdf` – RajaRaviVarma Feb 04 '15 at 18:36

6Be aware that convert uses ghostscript under the hood and gs will decode and reencode JPEGs which result in a loss of quality, even if speciiy a high quality. – tobltobs May 04 '15 at 09:28

6I had to create more than 6000 pdfs starting from 30000 tiffs. `convert` estimate time ~6-7 hours. I used `tiffcp` and `tiff2pdf`, they took few seconds. – j.c May 04 '17 at 10:15

You can install it via `sudo apt install imagemagick`. Otherwise you don't have the convert command. – Melroy van den Berg Aug 13 '18 at 18:50

3@Garret. No but there are several ways of converting an image to pdf, using covert for example or just print to pdf from many programs. Once the image is a pdf then you can use pdftk to join them together. – Warren Hill May 29 '14 at 07:22

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.

Works great for me, the only issue I had is some files are rotated. Is it possible it removes some metadata? – karizma Jan 04 '23 at 22:08
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.

1Hrm, my input tif files are 160M, but the pdf generated by tiff2pdf is about 820M. Not sure if this is really "just packing" things. – markasoftware Sep 08 '18 at 01:09

@markasoftware - In my case 90 MB multi.tiff was converted to a 365 MB pdf. Looking into it with `pdfimages -list`, under image type is listed `image`, which may mean uncompressed, with width/height `4600 /6408`. - Shrinking it to 300 dpi gave a 30 MB pdf with no sensible decrease of quality. – cipricus Jan 17 '22 at 14:17

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.

The OP is asking how to convert image1.tif image 2.tif image 3.jpg to images.pdf – Lexible Apr 25 '19 at 17:12
-
Not exactly. OP also wants merge pdf files with images. It is better to create pdf files from images using `img2pdf` command, since it creates pdf containing original image, and then use `pdfjoin`. – kubus Apr 27 '19 at 11:28
-
`pdftk` in 18.04: https://askubuntu.com/a/1165823/925128 (CLI only, as `pdfchain` is not available in 18.04 afaik) – cipricus Dec 04 '19 at 12:34

`pdfjoin` will also create pdfs from images, e.g. `pdfjoin -o images.pdf *.png` – David C. Rankin Sep 09 '21 at 18:10
I use PDF-Shuffler for this kind of use, it works great.

3I would downvote, but have not enough rep. PDF-Shuffler accepts only PDF files. Question also included image files and text files. – borisdiakur Jan 31 '14 at 12:17
-
With Libreoffice you can convert text files to pdf. As it is also possible to insert image files in Libreoffice, then convert in pdf. Once everything is in pdf, Pdf-Shuffler can do the job. But I don't think one software can do all the job at once. – cochisebt Jan 31 '14 at 15:24
-
As of 22.04, `pdfshuffler` (which has been renamed as "PDF Arranger") can do what the OP asked. I needed a multi-page PDF, consisting of two `jpg` images: just dragged them into a new blank canvas in PDF Arranger, saved as new PDF and voilà... – sxc731 Sep 11 '22 at 11:22
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.

This is interesting. OP, could you please demonstrate it with some sample code? – Nav Feb 06 '21 at 04:15
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}
Optional extra formatting:
To add images: https://www.sharelatex.com/learn/Inserting_Images
For different font sizes: https://www.sharelatex.com/learn/Font_sizes,_families,_and_styles
For different fonts: https://www.sharelatex.com/learn/Font_typefaces
To change page size and margins when using pdflatex:
\usepackage[pass,paperwidth=148mm,paperheight=210mm,margin=5mm]{geometry}

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.

This is the best answer in my case because one of the images was itself a PDF that required additional processing and `convert` was unable to properly, uh, convert it. I didn't expect GIMP to handle PDFs so well. Thank you! – Andy Mikhailenko May 24 '21 at 19:49

How is that done exactly? There is no gui option to export as pdf but the extension can be modified manually. At 260 pages as tif files it crashed though. – cipricus Jan 17 '22 at 13:20

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.

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
