Social media and web publishing
Convert Epson RAW photos to JPEG for immediate publishing. Get your shots online without importing into editing software.
File size reduction for sharing
Epson RAW files are 10-80 MB. Converting to JPEG dramatically reduces file size, making them practical for email attachments and messaging apps.

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