In Deutschland, Österreich und der Schweiz wird das RAS-Format häufig in spezialisierten Ingenieur- und Geoinformationssystemen verwendet, wo es für die Darstellung von Rasterdaten in älteren oder proprietären Anwendungen von Bedeutung ist. Es ist hierbei oft eine Brücke zwischen modernen Bildformaten und etablierten, aber nicht mehr weit verbreiteten Systemen.

About PNG to RAS Conversion

Short answer: yes, you can convert PNG to RAS online for free, and quality is well preserved with the right settings. Just upload your .png file to CocoConvert, pick RAS as the output, and click Convert. The whole process takes seconds.

Now for the details. PNG uses lossless compression and supports transparency, making it perfect for graphics, logos, and screenshots. RAS is a widely used file format. Converting between these two formats lets you convert between formats quickly.

Your PNG file is decoded and re-encoded as RAS. Converting PNG to RAS maintains high quality with CocoConvert's optimised encoder settings.

CocoConvert runs entirely online — no software to install, no account to create. Your files are encrypted during upload (TLS), processed on isolated servers in Germany, and permanently deleted after 24 hours. It works in Chrome, Safari, Firefox, Edge, and all mobile browsers.

Need to convert more than one file? Free users can do 5 per hour. Pro gets 100 per hour with files up to 5 GB each.
