Some metadata may not survive
Your ARW file may contain EXIF, MakerNote, XMP metadata. HDR has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
Die Umwandlung von ARW-Dateien in HDR-Formate ist im professionellen Umfeld, insbesondere in Bereichen wie Ingenieurwesen und CAD, von großer Bedeutung. ARW-Dateien, als Rohdatenformate von Sony-Kameras, enthalten eine Fülle an Bildinformationen, die durch die Konvertierung in HDR-Formate optimal genutzt werden können. Dies ermöglicht eine detailreichere Darstellung von Licht und Schatten, was für technische Visualisierungen und Präsentationen unerlässlich ist. Unser Dienst bietet Ihnen eine präzise und effiziente Lösung, um die volle Dynamik Ihrer Aufnahmen zu entfalten. Dabei legen wir größten Wert auf Datensicherheit und die Einhaltung europäischer Datenschutzstandards, damit Ihre sensiblen Projektdateien jederzeit geschützt sind. Vertrauen Sie auf eine spezialisierte Konvertierung, die den hohen Anforderungen Ihrer Branche gerecht wird.
- Architekturvisualisierungen
- Qualitätssicherung in der Fertigung
- Digitale Produktentwicklung
In der DACH-Region wird bei der Archivierung und Weitergabe von technischen HDR-Bilddaten oft auf die Einhaltung spezifischer Dokumentenstandards geachtet, um Interoperabilität und langfristige Lesbarkeit zu gewährleisten.
About ARW (SONY) to HDR Conversion
Short answer: yes, you can convert ARW to HDR online for free, and quality is well preserved with the right settings. Just upload your .arw file to CocoConvert, pick HDR as the output, and click Convert. The whole process takes seconds.
Now for the details. ARW is Sony's RAW photo format preserving the full dynamic range captured by the sensor. HDR (Radiance) is a high-dynamic-range image format used in lighting and rendering. Converting between these two formats lets you convert between formats quickly.
Full Name: ARW uses Sony Alpha RAW, while HDR uses Radiance HDR Image. Compression: ARW uses Lossless, while HDR uses Lossless. Transparency: ARW uses No, while HDR uses No.
Your ARW file is decoded and re-encoded as HDR. Converting ARW to HDR 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 ARW (SONY) to HDR
Your ARW image is decoded into raw pixel data, then re-encoded as HDR. No quality loss — pixel data is preserved exactly.
Your ARW file is decoded — the compressed/stored pixel data is expanded into raw RGB pixels
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
Is ARW to HDR conversion free?
Yes. CocoConvert offers free ARW to HDR 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 ARW to HDR 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 ARW file and the converted HDR file are both automatically deleted from our servers within 24 hours. They are never shared, sold, or analysed.
Does converting ARW to HDR lose quality?
Converting ARW to HDR maintains high quality with CocoConvert's optimised encoder settings.
Can I convert HDR back to ARW?
Yes, CocoConvert supports HDR to ARW 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.
