PEF to BMP — Format Comparison & Online Converter
Fast, instant PEF (PENTAX) to BMP conversion. No signup required. Just drop your .pef file and get .bmp in seconds.
Batch Settings
HDR data will be tone-mapped
Your PEF 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 PEF 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 PEF (PENTAX) to BMP Conversion
PEF (introduced 2003) and BMP (introduced 1986) are both image formats, but they differ in important ways. PEF is Pentax's RAW format preserving maximum image data from Pentax SLR sensors. BMP is an uncompressed raster format that preserves every pixel but produces very large files.
Full Name: PEF uses Pentax Electronic Format, while BMP uses Bitmap Image. Compression: PEF uses Lossless, while BMP uses None (uncompressed). Transparency: PEF uses No, while BMP uses No.
When you convert PEF to BMP, the goal is to improve file compatibility across devices. Your PEF 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 PEF file is decoded and re-encoded as BMP. The conversion involves 4 steps: (1) your pef 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 PEF 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 PEF conversion.
How to Convert PEF (PENTAX) to BMP
- 1
Upload .pef file
Select your PEF 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 PEF→BMP conversion profile.
- 3
Convert
The server-side engine decodes your PEF 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 PEF (PENTAX) to BMP
Your PEF image is decoded into raw pixel data, then re-encoded as BMP. No quality loss — pixel data is preserved exactly.
Your PEF 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

Should You Convert PEF (PENTAX) to BMP?
When to Convert
- ✓Your PEF 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 PEF (PENTAX) to BMP
"BMP will be smaller than my PEF file"
BMP uses no compression, so the output file is often larger than a lossy PEF. If you need a small file, BMP may not be the right choice.
Frequently Asked Questions
What is the difference between PEF and BMP?
PEF is Pentax's RAW format preserving maximum image data from Pentax SLR sensors. BMP is an uncompressed raster format that preserves every pixel but produces very large files. Full Name: PEF uses Pentax Electronic Format, while BMP uses Bitmap Image. Compression: PEF uses Lossless, while BMP uses None (uncompressed). Transparency: PEF uses No, while BMP uses No.
Does PEF to BMP conversion affect quality?
Your PEF 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, PEF or BMP?
PEF uses lossless compression. BMP uses none compression. The better choice depends on whether you prioritize file size or quality.
How long does PEF 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 PEF or BMP better for long-term storage?
BMP is better for archival since it preserves all original data.
