Visionaire requires images in PNG or WebP file format. For the best optimization, we recommend using WebP due to the better compression and overall smaller file-sizes, which range from about 10-75% reduction depending on the export settings used.
Please note that some image editing applications still lack support for the WebP format, so you might have to use a converter tool and keep your original image files handy. You may always preview WebP images by opening them in your web browser.
QUICK NOTE: Depending on the export settings used for your PNG files, your images might not display correctly in Visionaire Studio. For instance in Adobe Photoshop, the recommended settings are: "Color mode: RGB color > 8 bit" and "Background contents: transparent".

Converting images to WebP
JPG-PNG2WEBP
This free batch tool by Dionous Games was developed specifically for use with Visionaire Studio. It is able to convert your project’s JPG or PNG art to lossless WebP and also edits your .ved file, replacing the old file extensions with ".webp" (note that the replacement does not work with compressed .veb project files). The batch file makes use of the WebP library provided by Google.
- Download JPG-PNG2WEBP (from Dionous Games)
- Download cwebp.exe (from Google)
XnConvert
The XnConvert application by XnView is a batch image processor/converter, that comes with loads of macro actions and support for lots of different image formats including WebP. Export/Conversion is fairly quick, whether you drag in an entire folder, multiple files or a single file.
