More than 60 gems for Joomla 4 & 5 I can’t live without

by Marc Dechèvre



Present slides


I am always very happy to pay Developers for Joomla Extensions because they deserve it.

Some extensions are widely known because they are available on the Joomla! Extensions Directory™ and have excellent reviews.

But there are also many gems out there which are less known, for example because they are only available on Github.

In this article I wanted to share with you my own list of those little extensions that I use on most of my Joomla 4 websites, together with a few tips & tricks.

The vast majority of these extensions are open source (in which case I encourage you to contribute!) or at least free of charge.

I have gathered them in 9 themes:


Have fun and enjoy Joomla! ❤️💙🧡💚

2 I love them all

I love each of the following extension of course.

But I have limited time for this session so I added a ❤️ on the ones I want to focus on.

3 The Gems


3.1.1 Allow SVG in the Media Manager ❤️

What about allowing the upload of SVG images in the Media Manager? All it takes is 30 seconds to adapt the Options.

Txs Brian!

3.1.2 Responsive Images ❤️ The Responsive Images plugin itself

What about generating automatically AVIF & WEBP images and creating source sets (ie creating different sizes of each image in order be totally responsive) ?

Txs Dimitris! A CLI to generate all the resized images at once

[ added on 2023.08.23 ]

In combination with the previous plugin, this CLI (Command Line Interface) allows to have all images “resized” at once (instead of slowing the site down when a page gets visited for the first time)

Txs Dimitris!

3.1.3 A different folder for each User in the Media Manager

What about restricting access to a specific part of the images folder (images/user/userName, where userName is either the real or a hashed version of the user name). The plugin could be enabled per user group.

Txs Dimitris!

3.1.4 FTP, Pixabay, Pexels, Emoji, Filters directly in the Media Manager ❤️

What about seeing not only local files but also distant files in the Media Manager? And having Filters and other additional features?

Txs Allon!

3.1.5 Allowing Documents -PDF etc- in the Custom Field of Type Media

Want to have a Custom Field of Type Media which would allow to select not only Images but also (for example) Documents?

The paid version of DP Media mentioned just above allows this (and many more things)

Txs Allon!


3.2.1 Open Graph - images used when sharing on social media ❤️

What about automatically generating Open Graph images for your site’s pages, superimposing text and graphics over an image or solid color background

Txs Crystal!

3.2.2 Sharing Buttons ❤️

What about having lightweight Sharing Buttons with no javascript and no tracking?

Txs me!

3.2.3 Yoast SEO

What about having SEO tips when you edit an Article?

Txs Firecoders!

3.2.4 4SEO ❤️

What about having an SEO extension that does it all (Open Graph but also structured data, sitemap, internal linking content writing assistance, broken links, error pages, redirections, …)? Given all these features (and I still discover new ones every time I use it), this is a paid extension.

Txs Yannick G.!

3.2.5 SEOInfo❤️

What about having a free browser extension for Firefox, Chrome and chromium-based browsers such as Edge or Brave, displaying SEO information about visited pages and alerts you of SEO and performance issues?

Txs Yannick G.!


3.3.1 More Types of Custom Fields ❤️

What about having 26 new Types of Custom Fields (videos, maps, …) on top of the 16 native ones

Txs Tassos!

3.3.2 Chained Fields

What having having the ability to create cascading dropdown fields that dynamically change based on the previous selection? That is 1 of the 7 extra Types of Custom Fields you get with the paid version.

Txs Tassos!

3.3.3 Fields inception

What about nesting Custom Fields of Type Subform (a repeatable list consisting of other Custom Fields)

Txs Nicholas!

3.3.4 Filtering ❤️

What about adding the following kinds of filters for each category displayed in the frontend of your site: Subcategory / Tags / Custom fields

Txs Nicholas!

3.3.5 Sort by field ❤️

[ added on 2023.08.30 ]

What about sorting the articles in a category by the value of a custom field.

Txs Nicholas!

3.3.6 Lite Youtube

[ added on 2023.08.30 ]

Renders faster than a sneeze. Provide videos with a supercharged focus on visual performance. This custom element renders just like the real thing but approximately 224× faster.

Txs Brian!

3.3.7 Synchronize CF and Creation Date

[ added on 2023.09.13 ]

When you use Smart Search (or JFilter which allows to filter on Custom Fields… and also uses the Smart Search view - you can only order by - Relevance - Title - (Creation) Date

So when you display Events (where each Event is an Article having a Custom Field of Type Calendar in order to select the Date+Time of the event) by default you cannot order them by Date of Event.

This plugin allows to “copy-paste” that Date+Time from the Custom Field to the Creation Date… so that ordering the Articles by Creation Date simulates ordering the Articles by Date of Event…

Txs Elisa!

3.3.8 Conditional fields - showon

[ added on 2023.09.13 ]

Using conditional fields (“showon”) has been a very developer centric feature and since Joomla 4.3, that notion is available for Custom Fields.

Works also with Custom Fields of type Subform (“Repeatable” Custom Fields)

Txs to the contributors and txs Olivier for the presentation!


3.4.1 WYSIWYG ❤️

What about enabling true WYSIWYG for Joomla’s tinyMCE Editor?

By default it supplies only the required files for the Cassiopeia template but you can use it for any other template as well.

Txs Dimitris!

3.4.2 A different Edit Form per Category

What about customizing any back-end / front-end com_content Edit Form per Category?

What about improving the editing of articles in the front-end a little?

Txs Sigrid & Peter!

3.4.5 Better front-end edition

What about making editing content in the front-end of your Joomla 4 website distraction free?

Txs Brian!

3.4.6 Shortcuts in TinyMCE

What about having a set of keyboard shortcuts to use when creating content with Joomla 4 and the default editor (TinyMCE).

Txs Brian!

3.4.7 Customizing TinyMCE menus ❤️

This all started with a question I asked on the Joomla Facebook Group:

There are 2 ways to add Styles to the predefined menus of TinyMCE: - there is a native solution, playing with media.css (or editor.min.css) or its equivalent in a Child Template (note: make sure your classes are not set as .test but p.test for instance) - there is a better solution when using the above-mentioned

The WYSIWYG plugin adds ao the following 2 files - /media/templates/site/cassiopeia/js/style_formats.json - /media/templates/site/cassiopeia/js/formats.json

See more explanations about this (including the content of those files) at the bottom of

If you use a Child Template, you can simply put those file in your Child Template (which is handy and makes sure your files are never overwritten): - /media/templates/site/cassiopeia_MYCHILD/js/style_formats.json - /media/templates/site/cassiopeia_MYCHILD/js/formats.json

Note: in the case of multilingual websites, if those files in your Child Template do not “trigger” then simply make sure - that the Child Template is “default” for each language - and also that the Child Template is “default” (and not the Parent Template)

Txs Dimitris!

3.4.8 Customizing further TinyMCE ❤️

Wha about having a system plugin to customise TinyMCE beyond what Joomla lets you do?

Txs Nicholas!

3.4.9 Inserting Code in TinyMCE… with Code Highlighting ❤️

[ added on 2023.08.23 ]

If you want to use TinyMCE in Joomla! and its builtin “Insert/Edit code” feature, you need this plugin to have syntax highlighting on your site.

Txs Andre!


3.5.1 Translations with Deepl ❤️

What about translating all your content to other languages thanks to Deepl, directly from your Editor (so keeping all the HTML tags!)

Txs Pieter-Jan!

3.5.2 Artificial Intelligence with ChatGPT

Too lazy to create your own content? Want to use ChatGPT directly from your Joomla Editor?

What about creating Article or Categories in bulk, including the corresponding Menu Items?

Txs Alexandre!

What about importing/exporting your Articles in batch, including their Custom Fields, directly from a CSV file?

3.5.6 A super simple Form to let visitors -or administrators- create Articles from the front-end ❤️

This is just one example of what is possible with Convert Forms 4, I think only in the paid version.

Txs Tassos!

3.5.7 RO-CSVI in general ❤️

I have just mentioned 4 tools to import Articles in Joomla. It would not be fair not to mention the most complete tool afaik allowing import/export, being logically a paid extension.

Txs Roland!

3.5.8 RO-CSVI to import from Wordpress in particular

[ added on 2023.08.23 ]

Elisa shared this tip to import from Wordpress:

I just migrated a blog category so easily with RO-CSVI I am so happy.

  1. Exported the Wordpress Posts with:
    (SELECT guid FROM #__posts WHERE ID = meta.meta_value) AS introimage
    #__posts p
    #__postmeta meta ON (p.ID = meta.post_id AND meta.meta_key = '_thumbnail_id')
    p.post_type = 'post' AND p.post_status = 'publish';
  1. Imported with RO-SCVi

Everything is done!

NB: It seems Compojoom has a (paid) tool for J3 but the db export was enough for my usecase

In this section I mention tools which go beyond the Joomla realm but can be useful for Joomlers :)

3.9.1 php_grep

[ added on 2023.08.30 ]

This script will allow you to scan files of your website and search for a specific pattern; f.i. a word or a sentence.

Txs Christophe!

Txs Tom

3.9.3 aesecure_quickscan

[ added on 2023.08.30 ]

aeSecure QuickScan allows to scan your website for suspicious files: - red list: it recognizes more than 45.000 viruses - green list: it uses hashes to avoid to scan Joomla and WordPress native files (all versions)

In order to help users affected by the hack of a well-known extension, a 2.0 version has been released end of August 2023 which - is now compatible with PHP 8.2.9 - has now updated its green list with the hashes of all native & unchanged files of all Joomla versions up to 2023.08.30:

This will greatly accelerate the scan and reduce the number of false positives.

Txs Christophe!
