RB to PNG conversion is the process of transforming an RB eBook or document file into a PNG image file, producing one or more raster images that represent pages or graphics from the RB source. This conversion extracts page visuals, preserves layout and typography as images, and outputs lossless or compressed PNGs suitable for web display, screenshots, thumbnails, or archival use.

While RB files might store specialized data, PNG files prioritize image quality and web compatibility. Converting RB to PNG unlocks easier accessibility and broader usability for your images.
Keep source pages to under 2,000×2,000 pixels when possible to balance quality and processing time; very large page sizes increase memory use and conversion time.
To preserve text sharpness, export at a higher DPI (300+ for print, 150–300 for high-quality screenshots) rather than upscaling later.
Use PNG-8 with palette reduction for simple graphics to reduce file size; use PNG-24 for complex pages or photographs to avoid banding.
For large libraries, perform batch conversions with per-page file naming and ZIP packaging to streamline downloads and organization.
