The Images tool in cPanel does three things to images already on your server: creates thumbnails, resizes them, or converts between formats. It runs across an entire directory at once, so it’s built for batch jobs, not one-off edits.
Open it from cPanel home → Files → Images.
Thumbnailer
Generates thumbnails from every image in a folder. Useful for galleries that need consistent preview sizes. Originals stay untouched; thumbnails save into a sub-folder.
Scaler
Resizes images in a folder. Pick a width or height and Scaler updates the files in place.
Scaler overwrites originals. Make a backup of the directory first if you want to keep the unscaled versions.
Converter
Changes the file format of every image in a folder. Classic example: convert a folder of .jpg files to .png. Original files are replaced with the new format.
When to use which
| You want to | Use |
