TIFF Won't Open? Convert to HDR Instantly
Fast, instant TIFF to HDR conversion. No signup required. Just drop your .tiff file and get .hdr in seconds.
Batch Settings
Transparency will be lost
TIFF supports transparency, but HDR does not. Transparent areas will be filled with a solid color (typically white). If you need transparency, consider converting to PNG or WebP instead.
Layers will be flattened
TIFF supports multiple layers, but HDR does not. All layers will be merged into a single flat image. Keep your original TIFF file if you need to edit individual layers later.
Some metadata may not survive
Your TIFF file may contain EXIF, IPTC, XMP, ICC metadata. HDR has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
CMYK → RGB color conversion
Your TIFF file uses CMYK color space (designed for print). HDR uses RGB. Colors will be converted — some print-specific colors (especially deep blues and vivid oranges) may shift slightly. For critical color matching, use a calibrated ICC profile.

About TIFF to HDR Conversion
Dealing with a TIFF file that won't open on your device? You're not alone — TIFF compatibility issues are one of the most common reasons people search for a file converter. TIFF is an uncompressed or losslessly compressed format favoured in print, publishing, and professional photography.
The fix is simple: convert your TIFF to HDR. HDR (Radiance) is a high-dynamic-range image format used in lighting and rendering. This conversion lets you convert between formats quickly, solving the problem in seconds rather than hours of troubleshooting.
Full Name: TIFF uses Tagged Image File Format, while HDR uses Radiance HDR Image. Compression: TIFF uses Lossy & Lossless, while HDR uses Lossless. Transparency: TIFF uses Yes, while HDR uses No. TIFF supports transparency, but HDR does not. Transparent areas will be filled with a solid color (typically white). If you need transparency, consider converting to PNG or WebP instead.
CocoConvert processes your TIFF file on secure servers in Germany — upload, convert, download. Your files are encrypted via TLS and automatically deleted within 24 hours. No account needed, no software to install, and it works on any device with a browser.
This conversion is ideal when you When you specifically need a HDR file for your workflow. Common misconception: ""My file's transparent background will carry over to HDR"" — in reality, hdr doesn't support transparency. transparent areas become solid (usually white). save as png or webp if you need transparency.
The conversion engine behind CocoConvert uses FFmpeg, Sharp, and qpdf — the same open-source libraries trusted by Netflix, YouTube, and enterprise platforms. Pro users can batch convert up to 100 files at once.

What Happens When You Convert TIFF to HDR
Your TIFF image is decoded into raw pixel data, then re-encoded as HDR.
Your TIFF file is decoded — the compressed/stored pixel data is expanded into raw RGBA (with alpha channel) pixels
Transparency is resolved: transparent pixels are composited onto a white background
Pixels are re-encoded using Radiance HDR Image's lossless compression
Metadata (EXIF, ICC profiles) is transferred where HDR supports it
The HDR file is saved and ready for download

Frequently Asked Questions
Why won't my TIFF file open?
TIFF files may not open if your device lacks the right codec or application. Converting to HDR — a more widely supported format — usually resolves this. HDR (Radiance) is a high-dynamic-range image format used in lighting and rendering.
Is it safe to convert TIFF to HDR online?
Yes. CocoConvert encrypts your file via TLS, processes it on isolated servers in Germany, and permanently deletes it within 24 hours. Your files are never shared or analysed.
Will I lose quality converting TIFF to HDR?
TIFF supports transparency, but HDR does not. Transparent areas will be filled with a solid color (typically white). If you need transparency, consider converting to PNG or WebP instead. CocoConvert uses high-quality encoder defaults to preserve as much fidelity as possible.
How large can my TIFF file be?
Free users can convert files up to 250 MB each. Pro users get a 5 GB limit per file, and Business API users have custom limits.
Can I convert TIFF to HDR on my phone?
Absolutely. CocoConvert works in any modern browser — iOS Safari, Android Chrome, and all desktop browsers. No app required.
Versions are pinned in our worker Dockerfile and re-built via CI on every change.
