HDR to WPG Converter
Processing entirely on your device — large files may take a moment.
HDR (Radiance RGBE) stores floating-point high-dynamic-range pixels — the format of lighting data and HDRI environment maps. Convert WPG drawings to PNG to move legacy WordPerfect archives into modern systems.
iLoveConverter processes everything locally on your computer, which makes it private and fast: no upload wait, no server storage, no limits. Add as many files as you like — batch conversion is built in.

About the HDR format
HDR (Radiance RGBE) is the veteran high-dynamic-range format of lighting research and 3D rendering: pixels stored as a shared 8-bit exponent plus per-channel mantissas, letting one file hold both a sun and a shadow with no clipping. HDRI environment maps for 3D scenes are almost always HDR files.
Standard image viewers show it badly or not at all, because the values can exceed what a screen can display. Converting HDR to PNG tone-maps the file into an 8-bit preview — good for quick inspection, though the floating-point original remains the render-grade master.
+Strengths
- ✓True high-dynamic-range values
- ✓The standard of HDRI environment maps
- ✓Compact for its precision
!Limitations
- −Not display-ready — needs tone mapping
- −Viewer support is scarce
About the WPG format
WPG is the graphics format of WordPerfect Office, the word processor that dominated North American law offices and government agencies through the 1990s. WPG files embed both vector line art and bitmaps, which is why they still surface inside archived legal filings and municipal records.
Nothing modern reads WPG natively. Converting WPG to PNG rescues those drawings into a format that drops into any document, wiki or image library without a WordPerfect installation.
+Strengths
- ✓Holds both vector and bitmap art
- ✓Compact for its era
- ✓Widely present in legal archives
!Limitations
- −Legacy format, no modern support
- −Vector data may rasterize on convert
Why convert HDR to WPG?
Converting makes sense where the strengths of WPG meet what HDR cannot give you. Holds both vector and bitmap art Meanwhile Not display-ready — needs tone mapping One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this HDR to WPG converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Will I lose quality converting HDR to WPG?
No — WPG is a lossless format, so every pixel of the converted image matches your original HDR file. You can also adjust the quality/size balance before converting when the target format supports compression.
Can I convert several HDR files at once?
Yes — drop as many files as you like into the tool and they are converted in one batch. When more than one file comes out, everything is bundled into a ZIP for a single download.
Will transparent areas survive the conversion to WPG?
Transparency is kept whenever WPG actually supports an alpha channel. If the target format has none (like JPG), transparent areas are flattened onto a white background — that is a property of the format, not of this tool.
