4 Best Tools for Creating Fillable PDF Forms on Linux

Brief: In this article, you will find the best applications that can be used to create PDF files with fillable fields, also known as interactive forms, on Linux.

If you need a powerful tool to create and edit PDF files on Linux, you have plenty of applications to choose from. They all make it possible to perform basic editing operations, like merging pages, cropping pages, and adding annotations, and even offer sometimes advanced functionality.

However, not all PDF editors can create PDF forms – editable PDF files with interactive fields that can be filled out by other users. Such documents come in handy if you need to create a questionnaire, an admission form, or a sales contract, for example.

The list below includes solutions that run on various Linux distributions and allow you to generate PDF forms for free in Linux.


ONLYOFFICE Docs is a full-featured online office suite that handles text documents, spreadsheets, presentations, and fillable forms. This suite is completely open source, and its local implementation in combination with advanced security features, like JWT, makes it a reliable choice for technology enthusiasts and users who care about the privacy of their data.

ONLYOFFICE Docs easily integrate with various document management platforms and services through official connectors, such as Nextcloud, Nuxeo, ownCloud, SharePoint, Alfresco, Confluence, Chamilo, etc. In addition, the suite comes with a desktop app for Linux, Windows, and macOS.

One of the biggest advantages of ONLYOFFICE Docs is that it allows you to make fillable PDF forms using its word processor, so the whole process is quite simple and intuitive.

The solution supports various field types, e.g. text fields, images, radio buttons, drop-down lists, checkboxes, complex fields, email addresses, etc., and offers different configuration parameters.

For example, when working with text fields, you can specify the symbols that can be entered by others and choose the required format – None, Digits, Letters, Arbitrary Mask, and Regular Expression. It’s also possible to assign tags to the inserted fields and save the ready-made forms as PDF files with interactive fields for free.

Importantly, ONLYOFFICE Docs allow you to co-author fillable forms in real time. In this case, you can share a form template with other users and co-edit it together using a set of collaborative features – Version history, two co-editing modes, Track changes, comments, user mentions, chat, etc. This significantly improves the process of form creation in teams.


2. LibreOffice

LibreOffice is a comprehensive open-source office suite whose native file format is the Open Document Format (ODF), a standard format that is widely used by governments and organizations all over the world. Apart from ODF, LibreOffice seamlessly opens and saves documents in other popular formats, including those used by various versions of the Microsoft Office suite.

LibreOffice is 100% free, and everyone can use and distribute it at no cost. Many of the features that are available as paid add-ons in other office suites (such as the creation of fillable forms) are free. There are no additional fees, and everyone can use, share, modify, and install LibreOffice in Linux without limitations.

LibreOffice includes a number of applications for creating and editing files of different types. To create fillable PDF forms, Writer, the word processing component of the LibreOffice package, is used. It allows you to add text input fields, drop-down lists, radio buttons, checkboxes, and export documents as PDF forms.

OpenOffice’s native format is ODF and it can work with files created with other common office software packages. The suite can be downloaded and used at no cost for any purpose.
