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.
您手中的TIFF图片，承载着丰富的细节和高质量的色彩信息，是专业图像处理的基石。然而，当您希望这些精彩瞬间在最新的高动态范围显示设备上焕发新生，或是想在社交媒体上以更生动的方式分享时，TIFF的传统呈现方式可能无法完全发挥其潜力。将TIFF转换为HDR，不仅仅是格式的转变，更是视觉体验的升级。它能让光影对比更鲜明、色彩层次更丰富，带来更接近真实世界的视觉冲击力。无论是为了在高清屏幕上享受无与伦比的画质，还是为了让您的创作在数字世界中脱颖而出，这项转换都将是您不可或缺的工具。

在华语地区，尤其是在移动社交和游戏领域，对高动态范围内容的需求日益增长。许多智能手机和显示器已支持HDR，但传统TIFF文件若不转换为HDR，便无法充分利用这些设备的显示能力，影响最终的视觉效果。
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.

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.

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.
