How to convert RAS to PNG
- Add your .RAS file - drop it in the box above or click to browse.
- Convert it to .PNG in a few seconds.
- Download your new .PNG file.
What to expect
- The conversion is lossless: all pixel values from the RAS image are preserved exactly in the PNG.
- PNG supports transparency, but a RAS source has none, so the output is a fully opaque image.
- File size reflects lossless compression - smaller than uncompressed raster data, but larger than a lossy format would be for photos.
Frequently asked questions
Does converting RAS to PNG lose any quality?
No. PNG uses lossless compression, so every pixel from the RAS bitmap is preserved exactly. This is the recommended target when you want the image data kept intact.
Why convert RAS to PNG?
RAS is an obsolete Sun Raster format with little modern support, whereas PNG is a lossless, patent-free format that opens in every browser, OS, and image app. It is the natural everyday replacement for RAS.
Where can I open the PNG afterward?
Everywhere - all modern operating systems, browsers, and image editors read PNG natively with a double-click, no plugin required.
Will the file get bigger or smaller?
It depends on the image. PNG's lossless compression usually beats an uncompressed RAS, but for photographic content PNG files can still be large compared with lossy formats. Detail is never sacrificed for size.
