About this conversion
Easily convert your Sony ARW RAW image files to the FITS format with Convert2.co's powerful and free online tool. ARW, Sony's proprietary RAW image format, captures unprocessed sensor data. FITS (Flexible Image Transport System) is the standard astronomical data format, essential for scientific imaging and analysis. This converter ensures that your ARW data is accurately transformed into a FITS file, preserving critical information for astrophotography, scientific research, and image processing. Whether you're a professional photographer or an amateur astronomer, our ARW to FITS converter provides a seamless solution. Experience high-quality conversions without complex software installations. Simply upload your ARW files and get your FITS files ready in minutes.

ARW
ARW (Alpha Raw) is the proprietary RAW image file format used by Sony digital cameras. It contains minimally processed data directly from the camera's image sensor, offering greater editing flexibility than JPEGs. ARW files typically store 12-bit or 14-bit color depth, preserving a wide dynamic range and color information. This makes them ideal for professional photographers wanting to achieve specific looks in post-processing. ARW files are uncompressed or losslessly compressed, ensuring maximum image quality.
FITS
FITS (Flexible Image Transport System) is a widely used digital file format in astronomy and scientific imaging. Developed by the International Astronomical Union (IAU), it's designed to store, transmit, and process scientific data, including images and multi-dimensional arrays. FITS files can store extensive metadata, such as observation parameters, telescope settings, and calibration information, within their header. This makes them invaluable for reproducible scientific research and data sharing among astronomers and researchers.
Why Convert ARW → FITS?
Converting ARW to FITS is primarily beneficial for astrophotographers and scientific researchers. While ARW captures high-quality RAW data from Sony cameras, FITS is the industry standard for astronomical data. This conversion allows users to leverage powerful astronomical software (like PixInsight, IRAF, or DS9) that natively supports FITS. It enables detailed analysis, stacking, and processing of celestial images captured with Sony cameras, integrating them into standard astronomical workflows. For scientific applications, FITS ensures that all critical observational metadata is preserved alongside the image data, facilitating accurate analysis and publication.
ARW vs FITS
ARW files are camera-specific RAW files designed for general photography, offering extensive editing latitude with high bit depth and dynamic range. They are proprietary to Sony and primarily intended for post-processing in photographic software. FITS, conversely, is a universal standard in astronomy, optimized for storing scientific data and crucial metadata. While both formats capture detailed image information, FITS excels at including header information vital for scientific analysis, whereas ARW focuses on photographic flexibility. Converting ARW to FITS makes your Sony camera's captured data accessible and compatible with specialized astronomical tools and research pipelines.
❓ Frequently Asked Questions
How do I convert ARW to FITS?
To convert ARW to FITS, simply upload your ARW file(s) to our online converter. Select FITS as the output format, click 'Convert', and download your FITS file once the process is complete. It's a straightforward, multi-step process designed for ease of use.
Is the ARW to FITS conversion free?
Yes, Convert2.co offers a completely free online service for converting ARW to FITS files. You can convert as many files as you need without any hidden costs or subscriptions.
What is the quality of FITS output?
Our ARW to FITS converter is designed to maintain the integrity and quality of your original image data. While FITS is optimized for scientific data, the conversion aims to preserve resolution, color depth, and other critical attributes from the ARW source.
Can I convert multiple ARW files at once?
Currently, our ARW to FITS converter handles individual file uploads. For batch conversion needs, you may need to upload and convert your ARW files one by one. We are continuously working to improve our features.
