HDR data will be tone-mapped
Your HDR file may contain HDR (High Dynamic Range) data. PNG only supports standard dynamic range (SDR). Highlights and shadows will be compressed to fit the 8-bit range — subtle detail in very bright or dark areas may be lost.
在数字图像的世界里，HDR（高动态范围）文件以其惊人的细节和色彩深度，为我们呈现了超越普通屏幕所能捕捉的真实场景。它们是专业摄影师、电影制作人以及游戏开发者手中的利器，能够记录下从极亮到极暗区域的丰富信息。然而，当您想将这些视觉杰作分享给朋友，发布到社交媒体，或是在大多数设备上流畅查看时，HDR文件的巨大体积和特定的兼容性要求可能会带来一些不便。这时，将HDR转换为PNG就成了一个既高效又实用的选择。PNG格式不仅保留了图像的清晰度和色彩，更以其广泛的兼容性和无损压缩特性，确保您的作品能在各种主流平台和设备上完美呈现，让每一次分享都无需妥协画质。

在大陆地区，许多手游和摄影App导出的高动态范围图像，在直接分享到微信朋友圈时，常因兼容性问题导致色彩失真或无法预览。转换为PNG能有效解决这一痛点，确保图像以最佳状态呈现。
About HDR to PNG Conversion
Short answer: yes, you can convert HDR to PNG online for free, and some quality differences may occur depending on the format types. Just upload your .hdr file to CocoConvert, pick PNG as the output, and click Convert. The whole process takes seconds.
Now for the details. HDR (Radiance) is a high-dynamic-range image format used in lighting and rendering. PNG uses lossless compression and supports transparency, making it perfect for graphics, logos, and screenshots. Converting between these two formats lets you improve file compatibility across devices.
Full Name: HDR uses Radiance HDR Image, while PNG uses Portable Network Graphics. Compression: HDR uses Lossless, while PNG uses Lossless. Transparency: HDR uses No, while PNG uses Yes.
Your HDR file is decoded and re-encoded as PNG. Your HDR file may contain HDR (High Dynamic Range) data. PNG only supports standard dynamic range (SDR). Highlights and shadows will be compressed to fit the 8-bit range — subtle detail in very bright or dark areas may be lost.
CocoConvert runs entirely online — no software to install, no account to create. Your files are encrypted during upload (TLS), processed on isolated servers in Germany, and permanently deleted after 24 hours. It works in Chrome, Safari, Firefox, Edge, and all mobile browsers.
Need to convert more than one file? Free users can do 5 per hour. Pro gets 100 per hour with files up to 5 GB each.

What Happens When You Convert HDR to PNG
Your HDR image is decoded into raw pixel data, then re-encoded as PNG. No quality loss — pixel data is preserved exactly.
Your HDR file is decoded — the compressed/stored pixel data is expanded into raw RGB pixels
HDR data is tone-mapped to standard dynamic range (8-bit per channel)
Pixels are re-encoded using Portable Network Graphics's lossless compression
Metadata (EXIF, ICC profiles) is transferred where PNG supports it
The PNG file is saved and ready for download

Frequently Asked Questions
Is HDR to PNG conversion free?
Yes. CocoConvert offers free HDR to PNG conversion with generous daily limits — 25 minutes of processing time and up to 5 files per hour (250 MB each). Pro plans remove these limits.
How fast is HDR to PNG conversion?
Most files convert in 2–10 seconds depending on size. Large image files may take 30 seconds. Batch jobs process in parallel for maximum speed.
What happens to my files after conversion?
Your uploaded HDR file and the converted PNG file are both automatically deleted from our servers within 24 hours. They are never shared, sold, or analysed.
Does converting HDR to PNG lose quality?
Your HDR file may contain HDR (High Dynamic Range) data. PNG only supports standard dynamic range (SDR). Highlights and shadows will be compressed to fit the 8-bit range — subtle detail in very bright or dark areas may be lost.
Can I convert PNG back to HDR?
Yes, CocoConvert supports PNG to HDR conversion as well. However, if the original conversion involved lossy compression, converting back won't recover the lost data.
Versions are pinned in our worker Dockerfile and re-built via CI on every change.
