Fast, instant JPEG 2000 to OPENEXR conversion. No signup required. Just drop your .jp2 file and get .exr in seconds.
Batch Settings
Some metadata may not survive
Your JP2 file may contain EXIF, 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.
About JPEG 2000 to OPENEXR Conversion
Short answer: yes, you can convert JP2 to EXR online for free, and quality is well preserved with the right settings. Just upload your .jp2 file to CocoConvert, pick EXR as the output, and click Convert. The whole process takes seconds.
Now for the details. JP2 (JPEG 2000) offers wavelet-based compression with better quality than JPEG at the same bit rate. EXR (OpenEXR) is a high-dynamic-range format used in VFX, film, and 3D rendering pipelines. Converting between these two formats lets you convert between formats quickly.
Full Name: JP2 uses JPEG 2000, while EXR uses OpenEXR Image. Compression: JP2 uses Lossy & Lossless, while EXR uses Lossy & Lossless. Transparency: JP2 uses Yes, while EXR uses Yes.
Your JP2 file is decoded and re-encoded as EXR. Converting JP2 to EXR maintains high quality with CocoConvert's optimised encoder settings.
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 JPEG 2000 to OPENEXR
Your JP2 image is decoded into raw pixel data, then re-encoded as EXR.
Your JP2 file is decoded — the compressed/stored pixel data is expanded into raw RGBA (with alpha channel) 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
Is JP2 to EXR conversion free?
Yes. CocoConvert offers free JP2 to EXR 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 JP2 to EXR 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 JP2 file and the converted EXR file are both automatically deleted from our servers within 24 hours. They are never shared, sold, or analysed.
Does converting JP2 to EXR lose quality?
Converting JP2 to EXR maintains high quality with CocoConvert's optimised encoder settings.
Can I convert EXR back to JP2?
Yes, CocoConvert supports EXR to JP2 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.
