PEF
PEF is the camera RAW format of Pentax digital cameras. It stores unprocessed sensor data for later adjustment of exposure and color. PEF files need RAW-capable software, so they are often converted to JPG, PNG, or TIFF.

BMP
BMP (Bitmap) is a raster image format developed by Microsoft for Windows. It usually stores pixels without compression, so images keep full detail but files are large. BMP is mostly used by legacy software and is often converted to PNG or JPG to save space.
What happens when PEF becomes BMP
Source format
PEF is the image source or target format for this conversion path.
Target format
BMP is a simple bitmap format that is often uncompressed and therefore large.
What changes
The PEF pixels are decoded and written using BMP compression and color capabilities.
- What is preserved
- Pixel dimensions and visible composition are preserved unless resize or crop settings are selected.
- What may be lost
- Layers, editable vectors, camera-raw controls, animation, high bit depth, and metadata are preserved only when BMP supports them.
- Codec and quality implications
- Color profile handling, bit depth, chroma sampling, and compression settings can change appearance or file size.
- Realistic limitations
- Multi-page, layered, animated, camera-raw, or very large images may be flattened, reduced to one frame, or rejected if the decoder cannot safely read them.
Conversion steps
- Upload a PEF file no larger than 1 GB.
- Confirm that BMP is selected as the target.
- Download the BMP file and check the result before deleting your source.
Troubleshooting
- The PEF file is rejected or will not open.
- Confirm that the file is not empty, password-protected, or corrupt and that its real format matches the extension.
- The BMP file is larger than expected.
- Choose a more efficient codec or lower quality setting when available. Lossless and uncompressed targets are often larger by design.
- Transparency, color, or animation changed.
- Choose a target that supports the needed feature and keep the original file; JPG cannot store transparency or animation.
Privacy and file retention
Uploads and converted files are processed automatically and irreversibly deleted within 24 hours. You can delete them sooner with the delete control. Convertr does not read, mine, sell, or manually review file contents.
