Most image converters assume you're always online, but that's not always true — you might be working on a flight, in a location with unreliable or restricted internet, or on a secured computer that's intentionally kept off the network for security reasons. In any of these situations, an online image converter simply isn't an option, no matter how good it might otherwise be.
A desktop converter installed ahead of time solves this directly: once it's on your computer, it doesn't need to reach the internet at any point to actually convert images, since everything happens using your own machine's processing power.
- Install Turbo Batch Image Converter Pro on your Windows PC while you still have an internet connection, since the installer itself requires downloading.
- Once installed, the app is fully functional offline — no further internet access is needed for any conversion task.
- Open the app and load your images or folder, even on a fully disconnected machine.
- Choose your input and output formats and configure any resizing or quality settings you need.
- Click Convert. The entire process runs locally, with no network connection required at any step.
- Works on flights, in remote locations, or anywhere internet access is unreliable
- Compatible with secured or air-gapped machines that are intentionally disconnected
- No dependency on a server being available or responsive
- Conversion speed depends only on your own hardware, not connection quality
- Once installed, no further downloads or updates are required to keep converting
- Supports 25 standard formats plus 47 RAW camera formats entirely offline
Do I need internet access at any point after installing the software?
No, once installed, the app converts images entirely offline. An internet connection is only needed for the initial download and installation.
Can this be used on a computer that's intentionally kept off the network?
Yes, since the software doesn't require any network access to function, it's suitable for secured or air-gapped machines where connectivity is restricted by design.
Will conversion be slower without an internet connection?
No, since the software never relied on the internet for the conversion process itself, speed depends entirely on your computer's own hardware, regardless of connectivity.
