HDR to TIFF Converter
Processing entirely on your device — large files may take a moment.
Convert to TIFF when submitting scans or print-ready artwork where maximum fidelity is required. If your files are still in HDR format, this page is the shortcut: HDR (Radiance RGBE) stores floating-point high-dynamic-range pixels — the format of lighting data and HDRI environment maps.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.
How HDR compares to TIFF
| HDR | TIFF | |
|---|---|---|
| Compression | RGBE (RLE runs) | Lossless (LZW/ZIP) or none |
| Transparency | Not supported | Supported (alpha channel) |
| Animation | Not supported | Not supported |
| Metadata | Radiance comments | Rich tag system (EXIF, GeoTIFF) |
| Best for | Lighting data, environment maps | Print, scanning, archival |

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 TIFF format
TIFF, introduced by Aldus in 1986 and maintained by Adobe since, is the workhorse of the scanning, printing and archiving industries. It is a tag-based container: baseline RGB, CMYK, grayscale and indexed color, compressed with lossless LZW or ZIP (or not at all), with 8- or 16-bit depth and even multiple pages in a single file. A scanned contract or a print-ready magazine page lives in TIFF.
Its historical weakness is dialect fragmentation: the tag system is so flexible that exotic TIFFs — GeoTIFFs, fax TIFFs, certain 16-bit CMYK variants — still trip up careless readers. Files are huge, and no browser displays TIFF natively, so it never escaped its professional niches.
+ Strengths
- ✓Lossless with up to 16-bit-per-channel depth
- ✓Multipage support — one file, many scans
- ✓CMYK and print-industry color handling
- ✓Rich, extensible tag metadata for archiving
! Limitations
- −Very large files, even compressed
- −Dialect fragmentation trips up simple readers
- −No native browser display
Why convert HDR to TIFF?
There is a concrete reason this conversion exists: Not display-ready — needs tone mapping TIFF sidesteps that — Lossless with up to 16-bit-per-channel depth If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this HDR to TIFF 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 TIFF?
No — TIFF 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 TIFF?
Transparency is kept whenever TIFF 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.
