Joomla 3.9.21

I am working on a site that is very image heavy, most images are within the EasyBlog component and amount to approximately 8GB, the original administrators didn't optimise the images for web when uploading them.

I need to compress these images somehow so that they aren't taking up so much resources on the server, however I don't want to affect their dimensions or picture quality.

Rather than download all the images manually and bath process them in Photoshop and re-uplad I was looking for some ideas?

I know that Easyblog offer an image optimisation service but i'm wondering if I can somehow implement a similar reduction for free?

I'd go with a NodeJS approach because...why not, eh?

Step 1

Download all images and put them in a folder.

Step 2

Open your terminal (cmd, GitBash, etc) and navigate to your folder:

cd /path/my-folder

Step 3

Inside the folder, create a JS file (e.g compress.js) and add the following code:

const imagemin = require('imagemin')
const imageminWebp = require('imagemin-webp')
(async () => {
    await imagemin(['*.{jpg,png}'], 'compressed/images', {
        use: [
            imageminWebp({quality: 100})

Step 4

Run the JS file

node compress.js

Step 5

Run the following

npm install imagemin imagemin-webp
  • This looks great @Lodder thanks - what sort of reduction would you expect from this?

  • Well this converts the images to webp, which is a "next-gen" format, so you'll see quite a reduction. I'd suggest converting 1-2 images and adjusting the quality parameter, so you can guage the minimum. Please note I haven't tested this yet, so let me know if you run into any errors
