Uploading photos to an online converter means sending your files to someone else's server, which raises privacy concerns and is simply slower for large batches since every file has to be uploaded before it's even processed.
Turbo Batch Image Converter Lite runs entirely on your own Windows PC. No file is ever uploaded, no internet connection is required to convert, and your images stay exactly where you put them.

- Click Convert; the app processes every file locally.
- Find your converted files in the output folder, never having left your PC.

- Works with no internet connection required

Does the app ever send my images anywhere?
No, conversion happens entirely on your PC and no image data is uploaded or transmitted.
Do I need an internet connection to convert images?
No, the app converts images fully offline once installed.
Is this safer for private photos than an online tool?
Because nothing is uploaded, offline conversion avoids the privacy exposure that comes with sending files to a third-party server.
