Images are compressed in your browser, one at a time. Nothing is uploaded. WebP is selected by default so PNG images become materially smaller; their filename extension changes to .webp.

Questions

Are my image folders uploaded?

No. Images are compressed locally in your browser and are never uploaded to ToolDesk.

Are subfolders included?

Yes. The folder picker finds supported images recursively and recreates their relative folder paths inside the ZIP.

Will image filenames or formats change?

Folder paths and filename stems are preserved. WebP is the default for meaningful size reduction, so converted files use the .webp extension. You can choose JPG or keep each original format instead. Already-optimized files remain unchanged when conversion would make them larger.
