ARW to BMP for Image Workflows
Fast, instant ARW (SONY) to BMP conversion. No signup required. Just drop your .arw file and get .bmp in seconds.
Batch Settings
HDR data will be tone-mapped
Your ARW file may contain HDR (High Dynamic Range) data. BMP only supports standard dynamic range (SDR). Highlights and shadows will be compressed to fit the 8-bit range — subtle detail in very bright or dark areas may be lost.
Some metadata may not survive
Your ARW file may contain EXIF, MakerNote, XMP metadata. BMP has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
About ARW (SONY) to BMP Conversion
Whether you're one of the many photographers, designers, and content creators who work with ARW files daily, there comes a time when you need BMP instead. ARW is Sony's RAW photo format preserving the full dynamic range captured by the sensor.
Here's a typical scenario: you receive a .arw file but your project, platform, or client requires .bmp. BMP is an uncompressed raster format that preserves every pixel but produces very large files. Rather than searching for desktop software or wrestling with command-line tools, you can convert ARW to BMP online in seconds with CocoConvert.
This conversion is ideal when you Your ARW file won't open on a recipient's device or in an application, or when you A website, service, or platform only accepts BMP uploads. The conversion helps you improve file compatibility across devices.
Your ARW file may contain HDR (High Dynamic Range) data. BMP only supports standard dynamic range (SDR). Highlights and shadows will be compressed to fit the 8-bit range — subtle detail in very bright or dark areas may be lost. Common misconception: ""BMP will be smaller than my ARW file"" — in reality, bmp uses no compression, so the output file is often larger than a lossy arw. if you need a small file, bmp may not be the right choice.
Behind the scenes, CocoConvert uses industry-standard tools — FFmpeg for audio and video, Sharp for images, qpdf for documents. Your file is uploaded securely (TLS encryption), processed on isolated servers in Germany, and auto-deleted within 24 hours. No account, no watermark, no hidden fees.
Power users can batch convert up to 100 files simultaneously with a Pro subscription, making it practical for production workflows.

Your .bmp file is ready to plug into your workflow. Download it or share the link (expires in 24 hours).
What Happens When You Convert ARW (SONY) to BMP
Your ARW image is decoded into raw pixel data, then re-encoded as BMP. No quality loss — pixel data is preserved exactly.
Your ARW file is decoded — the compressed/stored pixel data is expanded into raw RGB pixels
HDR data is tone-mapped to standard dynamic range (8-bit per channel)
Pixels are re-encoded using no compression (raw pixel storage)
Metadata (EXIF, ICC profiles) is transferred where BMP supports it
The BMP file is saved and ready for download

Common Mistakes When Converting ARW (SONY) to BMP
"BMP will be smaller than my ARW file"
BMP uses no compression, so the output file is often larger than a lossy ARW. If you need a small file, BMP may not be the right choice.
Frequently Asked Questions
Who needs to convert ARW to BMP?
This conversion is commonly used by photographers, designers, and content creators. Typical reasons include improve file compatibility across devices and ensuring compatibility with downstream tools or platforms.
Can I convert ARW to BMP without losing quality?
Your ARW file may contain HDR (High Dynamic Range) data. BMP only supports standard dynamic range (SDR). Highlights and shadows will be compressed to fit the 8-bit range — subtle detail in very bright or dark areas may be lost.
Do I need to install software to convert ARW to BMP?
No. CocoConvert runs entirely in your browser — no downloads, no plugins. It works on macOS, Windows, Linux, iOS, and Android.
How many ARW files can I convert at once?
Free users can convert up to 5 files per hour. Pro subscribers get 100 files per hour with larger size limits (5 GB per file). Business API users can integrate batch conversion directly into their tools.
Is there an API for ARW to BMP conversion?
Yes. CocoConvert offers a Business API for automated conversions. It supports all the same format pairs available in the web interface, including ARW to BMP.
