Solution:

Webp format is not supported by PHP installation

It means your PHP GD library is installed, but WebP support is NOT enabled inside GD.

You are using:

/opt/lampp/htdocs/lucknoworbit.com

So this is XAMPP on Linux (LAMPP).

Step 1 — Check if WebP Support is Enabled

Run this command:

/opt/lampp/bin/php -i | grep -i webp

If you see:

WebP Support => enabled

Then it’s fine.

If nothing appears ❌ → WebP is not compiled in GD.

Step 2 — Check GD Details

Run:

/opt/lampp/bin/php -i | grep -i gd

Or create a phpinfo file:

<?php phpinfo(); ?>

Then open:

http://localhost/phpinfo.php

Look for:

GD Support => enabled
WebP Support => enabled (or disabled)

If WebP Support = disabled → this is your problem.

FIX OPTION 1 (Recommended) — Install WebP for GD

Since you’re using XAMPP (LAMPP), WebP support usually requires system libraries.

Install required libraries:

sudo apt update
sudo apt install libwebp-dev
sudo apt install libgd-dev

Then reinstall PHP GD extension

If you’re using system PHP:

sudo apt install php-gd

If using LAMPP bundled PHP → it may not have WebP compiled.

👉 In that case, easiest solution is:

FIX OPTION 2 (BEST & EASIEST) — Use Imagick Instead of GD

Imagick supports WebP much better.

Step 1: Install ImageMagick

sudo apt install imagemagick
sudo apt install php-imagick

Step 2: Restart Apache

sudo /opt/lampp/lampp restart

Step 3: Modify Intervention Image

In your Laravel config:

config/image.php

Change:

'driver' => 'imagick',

Instead of:

'driver' => 'gd',

Step 4: Test

/opt/lampp/bin/php -r "print_r(gd_info());"

OR test WebP save again.

Why This Happens

GD must be compiled with:

--with-webp

XAMPP often ships without WebP compiled in GD.

So GD exists ✔
But WebP support inside GD ❌

Best Practice for Production

For production servers:

✔ Use Imagick
✔ Avoid GD for modern formats
✔ Use WebP or AVIF

Imagick is more stable for:

• WebP
• Large images
• Memory efficiency
• Better compression

Quickest Solution For You

Since you are already using:

$manager = new ImageManager(["driver" => "imagick"]);

Just make sure:

php -m | grep imagick

If not found:

sudo apt install php-imagick
sudo /opt/lampp/lampp restart
