cwebp Runner

A minimal VS Code extension that batch-converts selected image files to WebP by calling the cwebp binary.

Features

• Convert one or many files from the Explorer context menu.
• Convert many files from the Command Palette via a file picker.
• Keep the original file basename and write filename.webp beside the source image.
• Configure the cwebp binary path and default arguments in VS Code settings.
• Optionally skip files when the target .webp already exists.
