Batch Rotate 4+

With just three clicks, thousands of your photos can be rotated or flipped at a time.

As a batch processing app, batchROTATE pays more attention to the original files' security and EXIF data. Instead of directly rotating them, your pictures will be processed and copied to a destination folder of your choice beforehand. Neither the geographic tag nor any EXIF data of your photos will be erased or rewritten during the process, so they won't be ruined during the process.

Part of dragonBTV's batch series, batchROTATE surely inherited the tradition of handling original files' security and the app's execution efficiency.
