Unlike a text file, you cannot edit a PDF directly. There are several ways to create PDF files with text. But what if you want to go the other way around and convert PDFs to text files?
Fortunately, with Linux, you can easily change these files from the terminal. This article shows how to convert a PDF file to a text document on Linux.
Convert PDF to text from the terminal
Poppler is a software library for rendering and modifying PDF files. It includes a utility known as pdftotextwhich allows users to generate text files from PDFs. Since poppler-utils is not part of the standard Linux package, you have to install it manually using a package manager.
On Ubuntu and Debian:
sudo apt install poppler-utils
To install Poppler on Arch Linux:
sudo pacman -S poppler
Installation of the poppler-utils Package on CentOS, Fedora, and other RHEL-based distributions is easy.
sudo dnf install poppler-utils
sudo yum install poppler-utils
Convert an entire PDF file to text
The basic syntax of the pdftotext command is:
pdftotext (options) pdffile text file
…Where PDF file is the absolute or relative path to the PDF file and Text file is the name of the output file.
For example to convert lorem-ipsum.pdf to a text file:
pdftotext lorem-ipsum.pdf text.txt
If the file being converted contains watermarks or misaligned text, you can discard them in the output -nodiag Flag.
pdftotext -nodiag lorem-ipsum.pdf random.text
Process pages within a certain range
Use the -f and -l Flag if you want to convert pages that fall within a certain range. For example, to convert pages one through five to convert lorem-ipsum.pdf send someone an SMS:
pdftotext -f 1 -l 5 lorem-ipsum.pdf output.txt
To convert only the first page of the PDF file:
pdftotext -f 1 -l 1 lorem-ipsum.pdf output.txt
Convert password-protected PDF files to text
Pdftotext can even convert password-protected PDFs into text files. The -upw and -opw Flags that stand for User password and Owner password Take care of the authentication process as you convert the PDF files.
pdftotext -upw password lorem-ipsum.pdf output.txt
pdftotext -opw password lorem-ipsum.pdf output.txt
Make sure you replace password with the password of the PDF file.
You can also combine multiple flags to get the output you want. For example, to convert pages one to three of a password-protected PDF file to text:
pdftotext -f 1 -l 3 -upw password lorem-ipsum.pdf output.txt
Convert PDF graphically to a text file
If working at the command line isn't your thing, you can convert PDFs to text files using graphics software like Caliber. It is an e-book management application that allows you to view, organize, and modify PDF files on your system.
Caliber is available in the official Linux distribution repositories and can be downloaded by anyone with a package manager.

sudo pacman – caliber S.
On RHEL-based distributions like CentOS and Fedora, you can download caliber using either DNF or Yum.
sudo dnf install caliber
sudo yum install caliber

Working with PDF files on Linux
If you want to share a document with someone, the most efficient way to do this is to convert it to PDF before sharing. In the past, users had to install a dedicated PDF viewer on their system to view PDF files, but now almost every browser has a built-in PDF viewer.
You can find several applications that allow a user to easily view and edit PDF files. Many Linux installations come with LibreOffice, an office software suite that can be used as a PDF editor.
