Convert OTB to ART

Understanding the otb and art file formats

OTB (Over The Air Bitmap) files are simple monochrome image files commonly used in older mobile phones for storing small icons or graphics. These files are compact and optimized for devices with limited display capabilities.

ART files, on the other hand, are most often associated with AOL's proprietary image format, used primarily for compressing graphics for faster web loading. ART files use a unique compression algorithm and are not widely supported outside of AOL software.

How to convert otb to art

Converting an OTB file to an ART file requires first converting the OTB image to a more common format (such as BMP or PNG), then converting that file to ART. Direct conversion tools are rare due to the niche nature of both formats.

Recommended software for otb to art conversion

• XnConvert: This free, cross-platform batch image converter supports OTB as an input format. You can use it to convert OTB to BMP or PNG.
• IrfanView (with plugins): IrfanView can open OTB files and export them to BMP or PNG. To do this, use File → Open to load your OTB file, then File → Save As and choose BMP or PNG.
• AOL ART Converter: Once you have a BMP or PNG, use a legacy tool like Graphic Workshop Professional or ReaConverter (older versions) to convert to ART. Note that ART support is limited and may require older software versions.

Step-by-step conversion process

1. Open your OTB file in XnConvert or IrfanView.
2. Export the image to BMP or PNG using File → Save As.
3. Open the BMP or PNG in a tool that supports ART export, such as Graphic Workshop Professional.
4. Save the file as ART using File → Save As and selecting the ART format.

Tips and considerations

• ART is a legacy format; modern software may not support it. Consider if conversion is necessary.
• Quality may be affected due to compression differences between OTB and ART.
• Always keep backups of your original files before conversion.
