ORF to BMP — Format Comparison & Online Converter
Fast, instant ORF (OLYMPUS) to BMP conversion. No signup required. Just drop your .orf file and get .bmp in seconds.
Batch Settings
HDR data will be tone-mapped
Your ORF 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 ORF file may contain EXIF, MakerNote 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 ORF (OLYMPUS) to BMP Conversion
ORF (introduced 2004) and BMP (introduced 1986) are both image formats, but they differ in important ways. ORF is Olympus's RAW photo format with full sensor data. BMP is an uncompressed raster format that preserves every pixel but produces very large files.
Full Name: ORF uses Olympus RAW, while BMP uses Bitmap Image. Compression: ORF uses Lossless, while BMP uses None (uncompressed). Transparency: ORF uses No, while BMP uses No.
When you convert ORF to BMP, the goal is to improve file compatibility across devices. Your ORF 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. Understanding these technical differences helps you choose the right format for your workflow.
Your ORF file is decoded and re-encoded as BMP. The conversion involves 4 steps: (1) your orf file is uploaded and the format is validated, (2) the file content is decoded into its raw representation, (3) the data is re-encoded in bmp format with optimal settings, (4) the converted file is ready for download.
CocoConvert's converter handles the entire pipeline server-side using FFmpeg, Sharp, and qpdf — battle-tested libraries used by streaming platforms and enterprise tools. Files are encrypted in transit and deleted within 24 hours.
This conversion is ideal when you Your ORF 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. For the opposite direction, CocoConvert also supports BMP to ORF conversion.
How to Convert ORF (OLYMPUS) to BMP
- 1
Upload .orf file
Select your ORF file by dragging it to the upload zone or using the file picker. Batch upload is available for multiple files.
- 2
Choose .bmp
Set BMP as the output format. The converter uses optimal settings based on the ORF→BMP conversion profile.
- 3
Convert
The server-side engine decodes your ORF file and re-encodes it as BMP. Processing time depends on file size and complexity.
- 4
Download result
Grab your converted .bmp file. Multiple output files can be downloaded together.
What Happens When You Convert ORF (OLYMPUS) to BMP
Your ORF image is decoded into raw pixel data, then re-encoded as BMP. No quality loss — pixel data is preserved exactly.
Your ORF 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
ORF (OLYMPUS) vs BMP — Detailed Comparison

Should You Convert ORF (OLYMPUS) to BMP?
When to Convert
- ✓Your ORF file won't open on a recipient's device or in an application
- ✓A website, service, or platform only accepts BMP uploads
- ✓You need maximum device and software compatibility
When NOT to Convert
- ✗You want to preserve HDR information — BMP only supports standard dynamic range
Common Mistakes When Converting ORF (OLYMPUS) to BMP
"BMP will be smaller than my ORF file"
BMP uses no compression, so the output file is often larger than a lossy ORF. If you need a small file, BMP may not be the right choice.
Frequently Asked Questions
What is the difference between ORF and BMP?
ORF is Olympus's RAW photo format with full sensor data. BMP is an uncompressed raster format that preserves every pixel but produces very large files. Full Name: ORF uses Olympus RAW, while BMP uses Bitmap Image. Compression: ORF uses Lossless, while BMP uses None (uncompressed). Transparency: ORF uses No, while BMP uses No.
Does ORF to BMP conversion affect quality?
Your ORF 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.
Which format has better compression, ORF or BMP?
ORF uses lossless compression. BMP uses none compression. The better choice depends on whether you prioritize file size or quality.
How long does ORF to BMP conversion take?
Most conversions finish in seconds. Larger files or complex image content may take 10–30 seconds. CocoConvert processes files in parallel for batch jobs.
Is ORF or BMP better for long-term storage?
BMP is better for archival since it preserves all original data.
