Free JPG to OTA Converter

Free JPG to OTA Converter is a straightforward piece of software you can use to transform common image files with the JPG format into OTA file type compatible with Nokia mobile phones.
It doesn't include complicated options or customization preferences, making it suitable for all user levels, even those less familiarized with graphic conversion tools.

Pay attention to the installer

The app was developed with the aid of .NET Framework, so you must have this software framework to get it up and running without any issues. However, because Free JPG to OTA Converter is ad-supported, it also offers to download and install additional components that it doesn't actually need to work properly, as well as to make some changes to your browser settings. Unless you're interested in these offers, they can be declined to make a clean setup.
As far as the GUI goes, the software utility has a single window with a minimalistic appearance, where you can drag and drop JPEG files while navigating disk directories in Windows Explorer or another file navigator.

Easily convert JPEG files to OTA format

Worth noting is that batch processing isn't supported, so you can convert only one file at a time. On the other hand, you can preview the loaded image in the panel before proceeding with the conversion job. All you have to do is indicate the saving directory and name of the new file (Nokia SMS .ota format). Afterward, you can transfer the file to your Nokia device to open it and inspect quality results.

Evaluation and conclusion

Although Free JPG to OTA Converter doesn't have a particularly rich set of options and configuration properties, it delivers a straightforward solution for generating OTA files from JPG images to read them on Nokia devices. CPU and RAM usage was low in our tests.
