Fast, secure HDR to TIFF conversion. No registration required.
Here is the short version — HDR is a raster image format with its own balance of compression, colour depth, and software support. Hence the need for TIFF. A HDR → TIFF operation is one of the simplest image jobs there is: same pixel grid, different wrapper. What genuinely changes is how lossy the codec is, whether alpha survives, and how large the final file ends up. KaijuConverter picks safe defaults for each of those and lets you override them under Advanced. Background. HDR is a raster image format with its own balance of compression, colour depth, and software support. Destination side, TIFF is the archival multi-page master format used in scanning, print and document pipelines.
Radiance HDR Image
Source formatHDR (Radiance) stores high dynamic range images for realistic lighting in 3D rendering.
TIFF Image
Target formatTIFF is a flexible, high-quality image format widely used in publishing, printing, and professional photography. It supports multiple compression methods and color spaces including CMYK.
Why convert HDR to TIFF
The real reason to move from HDR to TIFF is almost never picture quality — both raster formats store essentially the same pixels. It is about the tools downstream: which editors open the file natively, which CMSes upload it without transcoding, which social platforms accept it. Picking TIFF solves those edge cases at the cost of a short conversion step.
HOW TO CONVERT
HDR → TIFF
Provide the HDR
Click or drag to upload. We accept a single HDR file per job, with an optional queue of additional images for batch mode.
Encode to TIFF
The conversion decodes the HDR, resolves the colour space to sRGB and writes the TIFF container around the pixel data.
Save the TIFF
The download is streamed back over HTTPS. If you uploaded multiple files, a ZIP with all TIFF outputs is produced instead.
Common Use Cases
Share across platforms
Send TIFF files to anyone without worrying about whether they have the right software for HDR.
Embed in documents
Drop TIFF output into Word, Google Docs, PowerPoint, Notion or a website without conversion warnings.
Optimize size
TIFF often produces smaller files than HDR for web, email and storage.
Archive & future-proof
Store in a widely-supported format that will still open on future operating systems without legacy plugins.
HDR vs TIFF — Strengths and limitations
What each format does best, and where it falls short.
HDR Strengths
- True floating-point dynamic range in 32 bits per pixel.
- Simple format — easy to parse and generate.
- Standard for environment maps and lighting probes in 3D.
- 30+ years of continuous use in architectural rendering.
Limitations
- No compression — files are larger than OpenEXR or AVIF for equivalent quality.
- Only one channel set (RGB) — no alpha, no multi-layer like EXR.
- Not a web format.
TIFF Strengths
- Lossless by default — no generation loss on successive edits and saves.
- Supports any bit depth (1 to 32 bits per channel), any color model, any number of channels.
- Extensible tag system means vendor-specific data survives alongside standard tags.
- Multi-page containers are perfect for scanned documents, faxes, and DICOM-like stacks.
- Industry-standard for archival, museums, scientific imaging, and high-end print prepress.
Limitations
- File sizes are huge compared to JPEG/WebP/AVIF — often 10-30× larger.
- Not a web format — no browser displays TIFF natively.
- Ambiguous spec areas mean some TIFFs only open correctly in the tool that created them.

Quality & Compatibility
HDR-to-TIFF conversion does not change the visible content. Quality is capped by the HDR decode; re-encoding a lossy source at high quality cannot recover detail that was already discarded. For archival masters, keep the original HDR alongside the TIFF copy.
Tips for Best Results
- Large HDR files may look identical to small TIFF files for photographic content; pick quality based on end use, not headline megapixels.
- For print, export TIFF at 300 DPI minimum and check that the colour profile embedded matches the print shop specification.
- Batch-convert related HDR images in one pass so they share identical encoder settings and look consistent side-by-side.
Frequently Asked Questions
It depends on the codecs involved. If both HDR and TIFF are lossy, the pixels are re-encoded and a small amount of detail is discarded — invisible at default quality settings on photographs. If TIFF is lossless (PNG, TIFF, BMP) the output keeps every pixel of the decoded HDR exactly, but cannot recover detail that HDR had already compressed away.
Often yes, especially when TIFF is lossless. HDR tuned for efficient web delivery will usually produce smaller files than TIFF's default settings. If file size matters, drop the quality in Advanced or pick a more compressed target format instead.
KaijuConverter uploads over HTTPS, processes the image in an isolated container and deletes both the source and the output within two hours. No account is required, file contents are never logged, and we do not use uploads to train any model. For confidential material, the paid plan includes a data-processing agreement.
