Frequently Asked Questions
RAW files contain 12-bit of color data per channel. Converting to AVIF applies professional dcraw processing. Some quality reduction occurs with lossyAVIF compression, but results are excellent for sharing and web use.
dcraw automatically applies the camera's recorded white balance settings from your Pentax 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 Pentax 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.
Pentax RAW files from Pentax cameras require specialized software: Pentax Digital Photo Professional, Adobe Lightroom, Capture One, or RawTherapee. ChangeThisFile uses dcraw for server-side processing without requiring any software installation.
Pentax RAW captures full sensor data with 12-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 Pentax 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 12-bit RAW files require more processing time than standard images.
