About XPM to HDR Conversion

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

Now for the details. XPM is a widely used file format. HDR (Radiance) is a high-dynamic-range image format used in lighting and rendering. Converting between these two formats lets you convert between formats quickly.

Your XPM file is decoded and re-encoded as HDR. Converting XPM to HDR 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.

Your uploaded XPM file and the converted HDR file are both automatically deleted from our servers within 24 hours. They are never shared, sold, or analysed.

Does converting XPM to HDR lose quality?
