When to convert ARW to BMP
Use this conversion when your destination needs BMP and you have a ARW source. Keep the original so you can compare the result or try another supported format.
Color, transparency, bit depth, frames and metadata may change. A lossless destination does not guarantee identical data or recover lost detail. Processed images cannot recreate camera RAW sensor data.

How to Convert ARW to BMP
Follow these simple steps to convert your file in seconds.
Choose a ARW file
Select or drop one file up to 100 MB. Its extension must match this converter. Availability is checked before transfer.
Convert to BMP
Color, transparency, bit depth, frames and metadata may change. A lossless destination does not guarantee identical data or recover lost detail. Processed images cannot recreate camera RAW sensor data.
Download and check the result
Use Download after conversion completes. Open the result and check its content, quality and formatting before sharing it. Download links expire one hour after upload finishes. Uploaded and converted files are removed automatically by regular cleanup. Files may become unavailable sooner when the service restarts.
Tips for Converting ARW to BMP
Practical advice to get the best results from this conversion.
Why this conversion is worth doing
Sony Raw Image has a known limitation: proprietary format with no publicly available specification. BMP Image addresses this with a key advantage: completely lossless with no compression artifacts. Converting from ARW to BMP is most worthwhile when this specific trade-off matters for the way you intend to use the file.
Match the format to the actual workflow
Sony Raw Image is most commonly used for professional photography with sony alpha series cameras, while BMP Image is the standard for windows system graphics and clipboard operations. If your workflow is closer to the second pattern, converting makes sense. If you are still working in a context where ARW is the norm, converting may create unnecessary compatibility friction with collaborators or tools that expect the source format.
Watch for this limitation in the BMP output
BMP Image has its own limitation worth understanding before you commit: very large file sizes due to lack of effective compression. After the conversion completes, open the BMP file and verify that this limitation does not affect your specific use case — for some workflows it is irrelevant; for others it can be a deal-breaker.
Choose the right format for your content type
ARW and BMP suit different image types. Lossy formats like JPG work well for photographs with gradual color transitions, while lossless formats like PNG, BMP, and TIFF are better for graphics with sharp edges, text overlays, or flat areas of color. Picking the wrong format can introduce artifacts or unnecessarily inflate file sizes.
Understanding ARW and BMP Formats
Learn about the source and target file formats to understand what happens during conversion.
Source Format
Sony Raw Image
image/x-sony-arwARW (Alpha Raw) is Sony's proprietary raw image format used by Sony Alpha mirrorless and DSLR cameras. Based on the TIFF specification, it stores unprocessed 12-bit or 14-bit sensor data with complete metadata. ARW files can be either uncompressed or use Sony's lossy or lossless compressed raw encoding.
Advantages
- Preserves full unprocessed sensor data for maximum post-processing latitude
- Supports both compressed and uncompressed raw storage options
- Well-supported by major photo editing applications including Lightroom and Capture One
Limitations
- Proprietary format with no publicly available specification
- Large file sizes, especially in uncompressed mode
- Requires raw-capable software for viewing and editing
Common Uses
- Professional photography with Sony Alpha series cameras
- Raw photo editing and non-destructive development
- High-quality archival of photographic captures
Target Format
BMP Image
image/bmpBMP (Bitmap) is an uncompressed or minimally compressed raster image format developed by Microsoft. It stores image data pixel by pixel with no quality loss, supporting color depths from 1-bit monochrome to 32-bit with alpha. BMP files are typically very large because most implementations store raw pixel data without compression.
Advantages
- Completely lossless with no compression artifacts
- Simple format that is fast to read and write
- Native support in all Windows applications
Limitations
- Very large file sizes due to lack of effective compression
- Not suitable for web use due to excessive file sizes
- Limited metadata support compared to modern formats
Common Uses
- Windows system graphics and clipboard operations
- Intermediate format in image processing pipelines
- Legacy application compatibility
