TIFF to HDR Converter
Processing entirely on your device — large files may take a moment.
TIFF is the standard format of the scanner, fax and print industries. It stores very high quality — usually lossless — and can hold multiple pages in one file, at the cost of large file sizes. Converting HDR to PNG produces a tone-mapped preview usable in any image viewer.
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.
How TIFF compares to HDR
| TIFF | HDR | |
|---|---|---|
| Compression | Lossless (LZW/ZIP) or none | RGBE (RLE runs) |
| Transparency | Supported (alpha channel) | Not supported |
| Animation | Not supported | Not supported |
| Metadata | Rich tag system (EXIF, GeoTIFF) | Radiance comments |
| Best for | Print, scanning, archival | Lighting data, environment maps |

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
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
Why convert TIFF to HDR?
There is a concrete reason this conversion exists: Very large files, even compressed HDR sidesteps that — True high-dynamic-range values If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this TIFF to HDR 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 TIFF to HDR?
No — HDR is a lossless format, so every pixel of the converted image matches your original TIFF file. You can also adjust the quality/size balance before converting when the target format supports compression.
Will transparent areas survive the conversion to HDR?
Transparency is kept whenever HDR 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.
What happens to EXIF data and other metadata?
Conversions here re-encode the image, and re-encoding generally does not carry the original metadata over. If the EXIF data of your TIFF files matters (camera model, GPS, timestamps), keep the original file as the master and treat the converted copy as the shareable version.
