Convert iPhone ProRaw film negative scans to positives online.
Negative Converter can open iPhone ProRaw DNG files from camera-scanned film and convert them to positive images locally in the browser. It is free, private, and works without a Lightroom or Photoshop workflow.
Can an iPhone scan film negatives?
HEIC and HEIF camera photos can also be imported directly. The app tries the browser decoder first and falls back to a bundled local WASM decoder; there is no upload or intermediate JPEG conversion step.
Yes. An iPhone that supports ProRaw can photograph a backlit 35mm or medium format negative as a DNG file. Negative Converter then inverts the negative, corrects the mask, and exports a positive image without sending the photo to a server.
The scan quality depends on even illumination, focus, film flatness, and avoiding reflections. A copy stand, stable holder, clean light source, and manual exposure help more than any software correction later.
Recommended capture setup
- Use a clean, even light source behind the negative.
- Keep the film flat and parallel to the phone camera.
- Use ProRaw DNG if available to preserve tonal range.
- Expose so highlights are not clipped in the film base.
- Crop out the holder and keep the unexposed border if you want better mask sampling.
ProRaw conversion steps
- Capture the negative as an iPhone ProRaw DNG.
- Open Negative Converter and select the DNG file.
- Crop to the frame and use Auto Frame if the border is visible.
- Select Color Negative, B&W Negative, or Positive mode.
- For color negative film, sample the orange mask from the border or use auto detection.
- Use gray point sampling and color controls to finish the image.
Why use a browser converter for ProRaw?
Phone film scans are often quick tests or personal archive images. A browser converter lets you review and finish them without creating a full desktop editing session. Because Negative Converter processes locally, the ProRaw file stays on the device.
Frequently asked questions
Can I convert iPhone ProRaw film scans without uploading?
Yes. Negative Converter parses iPhone ProRaw DNG files in the browser and converts the film negative locally, so the image is not uploaded.
Does iPhone ProRaw work for 35mm film scanning?
Yes. iPhone ProRaw can be used for 35mm film scanning when the negative is held flat, evenly lit, and photographed sharply.
