More than 60 gems for Joomla 4 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 ❤️

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, it 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!

Txs me!

3.2.3. Yoast SEO

What about having SEO tips when you edit an Article?

Txs Firecoders!

3.2.4. SEO ❤️

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.!


3.3.1. 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!

Txs Nicholas!

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!


3.4.1. 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.

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

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:

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):

Note: in the case of multilingual websites, if those files in your Child Template do not “trigger” then simply make sure

Txs Dimitris!

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

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!

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 wp_posts WHERE ID = meta.meta_value) AS introimage
wp_posts p
wp_postmeta meta ON (p.ID = meta.post_id AND meta.meta_key = '_thumbnail_id')
p.post_type = 'post' AND p.post_status = 'publish';

2) 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
