RAW files capture every bit of sensor data your camera records, which is perfect for editing but inconvenient for sharing, archiving, or working in tools that expect standard image formats. PNG is a good target when you want a lossless, widely compatible file without JPG's compression artifacts — useful for archival exports or images you plan to edit further in another application.
Uploading hundreds of RAW files to an online converter is slow, often restricted by file size limits, and risky if your shoot includes unreleased or client-confidential work. A desktop tool that converts entirely offline removes all three concerns, letting you batch-process a full shoot locally on your own machine.
- Install Turbo Batch Image Converter Pro, which supports 47 RAW camera formats and runs entirely offline once installed.
- Open the app and select Batch Mode to process a full folder of RAW files at once.
- Drag in your RAW folder, enabling recursive sub-folder scanning if your shoot is split across multiple session folders.
- Set the input format to RAW (or your specific camera format) and the output format to PNG.
- Optionally apply resizing during the same step if you need specific output dimensions.
- Click Convert. The app demosaics each RAW file locally and writes lossless PNG files to your output folder — nothing is ever sent online.
- Fully offline conversion, ideal for confidential or unreleased photo shoots
- Supports 47 RAW camera formats including CR2, CR3, NEF, ARW, and DNG
- Lossless PNG output preserves detail with no further compression artifacts
- Recursive folder scanning handles multi-session shoot structures automatically
- Multi-core processing speeds up large batch jobs
- No upload limits, account requirements, or per-file restrictions
Why choose PNG instead of JPG for RAW exports?
PNG is lossless, so it's a better choice when you want to preserve maximum detail for further editing or archival purposes, whereas JPG is better suited for smaller, shareable files.
Can I convert a full multi-folder photo shoot at once?
Yes. Recursive sub-folder scanning means the app finds and converts RAW files across nested folders without requiring you to flatten your shoot's folder structure first.
Is this conversion process private and offline?
Yes. All RAW processing and PNG encoding happens locally on your computer, so your photos are never uploaded to any external server.
