Need to turn a Radiance HDR file into a PPM file? This converter does it in seconds and downloads the result automatically. Drop in your Radiance HDR file (a .hdr) and download a ready-to-use PPM file (a .ppm) — no software to install, no account to create, and no watermark on the output.
Radiance HDR is an image format. Converting to or from it lets you use the same picture in apps and on platforms that expect a different format.
PPM is an image format. Converting to or from it lets you use the same picture in apps and on platforms that expect a different format.
The usual reason to convert Radiance HDR to PPM is file size or quality: PPM fits the job better, whether that means a smaller download, a cleaner edit, or broader support. Under the hood the conversion runs on libvips and ImageMagick — the same libraries that power image pipelines across the web — so colour, transparency and metadata are handled correctly wherever the target format supports them.
Typical uses: preparing assets for a website, attaching a file someone else can definitely open, or standardising a folder of mixed files into one format.
Privacy is the default here. Your Radiance HDR file is uploaded over an encrypted connection, converted, downloaded the moment it's ready, and then deleted automatically a short time afterwards. We never keep your files, never build a library of your content, and never make you sign up to download the result.
