About the Formats
☀️ What is HDR (Radiance)?
HDR (High Dynamic Range) format, also known as Radiance .hdr, stores floating-point pixel data capturing a wide range of luminance levels. It's commonly used in 3D rendering, lighting simulation, and high-end photography. HDR images require tone mapping for display on standard monitors.
All HDR conversion tools →📸 What is JPG (JPEG)?
JPG is the ubiquitous image format created in 1992. It uses lossy compression to achieve small file sizes with millions of colors. JPG is supported everywhere — from cameras to websites — and is ideal for sharing and previewing images.

💡 For archiving: keep HDR →Format Comparison
| Format | HDR | JPG |
|---|---|---|
| Compression | Lossless | Lossy |
| Transparency | No | No |
| File Size | Larger | Smaller |
Need to preserve the full dynamic range? Keep the original HDR file. For sharing and previews, HDR to JPG is ideal. For lossless 8‑bit output, try HDR to PNG.
💡 Pro Tips
- HDR images contain high dynamic range data. Our tone mapping converts this to a standard 8‑bit JPG that looks natural on any screen.
- Adjust exposure in advanced settings if the result is too dark or too bright.
- If your HDR is used for 3D rendering, you may want to keep the original for future compositing.
- Convert in batch mode — upload multiple HDRs and download all JPGs as a ZIP archive.
- We strip metadata by default for privacy, but you can keep EXIF by toggling the option before conversion (rare in HDR).
- For final delivery, always keep the original HDR master. Use JPG for previews and web sharing.
How HDR to JPG Conversion Works
HDR (Radiance) format stores pixel values as floating-point numbers, capturing a much wider range of light than standard 8‑bit images. This allows it to represent everything from deep shadows to bright highlights. JPG, by contrast, uses 8‑bit integers and is designed for standard dynamic range displays.
When you convert HDR to JPG, we first decode the HDR data, then apply tone mapping — a process that compresses the high dynamic range into the limited range of a standard JPG while preserving visual detail and contrast. You can control this process with exposure, gamma, and contrast sliders in advanced settings.
The result is a standard JPG file that faithfully represents your HDR image on any screen. All processing is done in memory, and your files are permanently deleted after 10 minutes.
HDR vs JPG: Key Differences
Dynamic range: HDR stores floating-point data with unlimited dynamic range; JPG is limited to 8‑bit standard range.
Use cases: HDR is used in 3D rendering, lighting simulation, and advanced photography; JPG is for sharing, web, and everyday use.
File size: HDR files can be large due to floating-point precision; JPG compresses aggressively, making it ideal for quick sharing.
When to Convert HDR to JPG
Convert HDR to JPG when you need to share your work with clients, post on social media, or create quick previews. JPGs are universally compatible and much smaller. Always keep your original HDR files for further editing or rendering.
For lossless 8‑bit output, consider HDR to PNG. If you need to preserve the HDR data, keep the original format.
