When to Convert
Common scenarios where this conversion is useful
Sharing Leica photos without RAW software
Not everyone has Lightroom or Capture One. Converting your Leica RAW files to BMP lets anyone view and use your photos with standard image viewers.
Quick delivery of client proofs
Photographers can quickly convert Leica RAW selects to BMP for client review. Fast delivery with professional quality, without the full RAW editing workflow.
Social media and web publishing
Convert Leica RAW photos to BMP for immediate publishing. Get your shots online without importing into editing software.
File size reduction for sharing
Leica RAW files are 10-80 MB. Converting to BMP dramatically reduces file size, making them practical for email attachments and messaging apps.

Frequently Asked Questions
RAW files contain 14-bit of color data per channel. Converting to BMP applies professional dcraw processing. Lossless output preserves all processed image data.
dcraw automatically applies the camera's recorded white balance settings from your Leica RAW file. For creative control over exposure and color temperature, use dedicated RAW software like Lightroom first.
The web interface handles one file at a time. For batch processing, use the authenticated API (/v1/convert) which supports automated workflows.
Your Leica RAW file is uploaded via encrypted TLS, processed using dcraw, and automatically deleted immediately after conversion. We never store or analyze your photos.
The web converter accepts files up to 25MB (Pro: 500MB). Most RAW files from consumer cameras fit within this limit. High-megapixel cameras may produce larger files suited to the API.
Leica RAW files from Leica cameras require specialized software: Leica Digital Photo Professional, Adobe Lightroom, Capture One, or RawTherapee. ChangeThisFile uses dcraw for server-side processing without requiring any software installation.
Leica RAW captures full sensor data with 14-bit per channel, preserving maximum detail and dynamic range. Unlike in-camera JPEG, RAW files let you adjust white balance, exposure, and color in post-processing without quality loss.
The conversion focuses on pixel data. EXIF metadata (camera settings, GPS, date) from the original Leica RAW file is not carried to the output. Keep the original RAW file if metadata preservation is needed.
RAW processing with dcraw typically takes 5-20 seconds depending on file size and server load. Large 14-bit RAW files require more processing time than standard images.
