Generation loss — quality may degrade
JPEG uses lossy compression and EXR typically uses lossy mode. Converting means decoding and re-encoding — each cycle can permanently degrade quality. Convert from the original source file whenever possible.
Some metadata may not survive
Your JPEG file may contain EXIF, IPTC, XMP, ICC metadata. EXR has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
您是否曾遇到这样的情况：一张张精心拍摄的JPEG照片，在需要进行深度后期处理、制作电影特效，或是融入游戏场景时，却显得力不从心？JPEG虽然方便分享，色彩信息却有所局限。而EXR格式，凭借其高动态范围（HDR）和无损特性，能够承载远超普通图像的色彩与亮度数据，为您的创意作品提供无限可能。从细致入微的光影调整，到复杂的三维渲染，EXR都能确保图像细节的完整保留。现在，无需繁琐的专业软件，我们的工具能帮助您轻松将JPEG转换为EXR，让您的视觉内容焕发新生，满足各种专业级应用的需求。让每一次转换都成为您作品质量的飞跃。

About JPEG to OPENEXR Conversion
Dealing with a JPEG file that won't open on your device? You're not alone — JPEG compatibility issues are one of the most common reasons people search for a file converter. JPEG uses lossy compression optimised for photographic content, balancing quality against file size.
The fix is simple: convert your JPEG to EXR. EXR (OpenEXR) is a high-dynamic-range format used in VFX, film, and 3D rendering pipelines. This conversion lets you convert between formats quickly, solving the problem in seconds rather than hours of troubleshooting.
Full Name: JPEG uses JPEG Image, while EXR uses OpenEXR Image. Compression: JPEG uses Lossy, while EXR uses Lossy & Lossless. Transparency: JPEG uses No, while EXR uses Yes. JPEG uses lossy compression and EXR typically uses lossy mode. Converting means decoding and re-encoding — each cycle can permanently degrade quality. Convert from the original source file whenever possible.

Once done, download your .exr file. For batch jobs, download all at once as a zip.
What Happens When You Convert JPEG to OPENEXR
Your JPEG image is decoded into raw pixel data, then re-encoded as EXR.
Your JPEG file is decoded — the compressed/stored pixel data is expanded into raw RGB pixels
Pixels are re-encoded using OpenEXR Image's lossless compression
Metadata (EXIF, ICC profiles) is transferred where EXR supports it
The EXR file is saved and ready for download

Frequently Asked Questions
Why won't my JPEG file open?
JPEG files may not open if your device lacks the right codec or application. Converting to EXR — a more widely supported format — usually resolves this. EXR (OpenEXR) is a high-dynamic-range format used in VFX, film, and 3D rendering pipelines.
Is it safe to convert JPEG to EXR 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 JPEG to EXR?
JPEG uses lossy compression and EXR typically uses lossy mode. Converting means decoding and re-encoding — each cycle can permanently degrade quality. Convert from the original source file whenever possible. CocoConvert uses high-quality encoder defaults to preserve as much fidelity as possible.
How large can my JPEG 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 JPEG to EXR 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.
