-## Bash script to optimize your images and convert them in WebP
-
-![img-optimize](https://raw.githubusercontent.com/VirtuBox/img-optimize/master/img-optimize.png)
-
-### Prerequisite
-
-* jpegoptim
-* optipng
-* WebP
-
-Debian/Ubuntu :
-
-```bash
-sudo apt install jpegoptim optipng webp -y
-```
-
-Centos 7  :
-
-```bash
-sudo yum install optipng jpegoptim libwebp-tools -y
-```
-
----
-
-### Installation
-
-1) Download the script
-
-```bash
-git clone https://github.com/VirtuBox/img-optimize.git $HOME/.img-optimize
-```
-
-2) Add an alias in your bashrc
-
-```bash
-echo "alias img-optimize=$HOME/.img-optimize/optimize.sh" >> $HOME/.bashrc
-source $HOME/.bashrc
-```
-
-### Usage
-
-```bash
-Usage: img-optimize [options] <image path>
-  Options:
-       --jpg <image path> ..... optimize all jpg images
-       --png <image path> ..... optimize all png images
-       --webp <image path> ..... convert all images in webp
-       --nowebp <image path> ..... optimize all png & jpg images
-       --all <image path> ..... optimize all images (png + jpg + webp)
- Other options :
-       -h, --help, help ... displays this help information
-Examples:
-  optimize all jpg images in /var/www/images
-    img-optimize --jpg /var/www/images
-
-```
-
-### Update the script
-
-To update the script, just run :
-
-```bash
-git -C $HOME/.img-optimize pull
-
-source .bashrc
-```
-
-### Setup daily cronjob
-
-You copy the scripts to /etc/cron.daily :
-
-```bash
-cp $HOME/.img-optimize/crons/jpg-png-cron.sh /etc/cron.daily/jpg-png-cron
-cp $HOME/.img-optimize/crons/jpg-png-cron.sh /etc/cron.daily/webp-cron
-
-chmod +x /etc/cron.daily/jpg-png-cron
-chmod +x /etc/cron.daily/webp-cron
-```
-
-Then just edit your websites path set with the variables `sites` at the beginning of the cron scripts.
-
-### Warning
-
-Conversion process can take a while, you can use `tmux` to launch the script and be able to close your ssh connection without interrupting conversion. Then just use `tmux attach` to login back in your tmux session.
-
-### Credits
-
-WebP conversion script was inspired by this [DigitalOcean Community Tutorial](https://www.digitalocean.com/community/tutorials/how-to-create-and-serve-webp-images-to-speed-up-your-website)
+# Image optimization bash script
+
+![img-optimize](https://gitea.avc.cx/borekon/img-optimize/raw/branch/master/img-optimize.png)
+
+The changes from the [original repo](https://github.com/VirtuBox/img-optimize) is that the EXIF data is **preserved**.

+## Prerequisite
+
+- jpegoptim for jpg optimization
+- optipng for png optimization
+- cwebp for WebP conversion
+- go-avif for Avif conversion
+
+### From APT repositories
+
+Debian/Ubuntu :
+
+```bash
+sudo apt install jpegoptim optipng webp -y
+```
+
+Centos 7 :
+
+```bash
