About BW (.bw)
BW in this toolchain usually labels a single-channel grayscale raster, often following SGI/IRIS naming where red/green/blue split files exist as siblings. The .bw file itself may lack a rich header—dimensions can live in a separate spec or companion file.
Treat samples as unsigned unless documentation states otherwise; 16-bit scientific dumps are common. Scaling to 8-bit display requires an explicit range map (min/max stretch, percentile clip, or physical calibration). Without metadata, aspect ratio and pixel aspect are unknown assumptions.
How to use
- From this hub, open “Any supported format” for the full picker, or pick a page such as “PNG image converter” for a focused SEO entry.
- On any child page, upload an image, choose the target format, then download the converted file.
- Watch transparency support because formats like JPG do not preserve alpha channels.
- Verify metadata, color profile, and visual output in your target app or browser.
