Download individual files or collect multiple results in one ZIP.
FORMAT GUIDE
What happens when DNG becomes JPG?
DNG contains raw image data. LokalPix develops it with the bundled local RAW library, then encodes the visible result as JPG.
DNG
Apple ProRAW uses DNG
Apple stores ProRAW captures as .dng files. Many cameras and photography apps also use Digital Negative as a RAW container.
JPG
Compact and compatible
JPG opens in virtually every image editor, office document and web service. The selected quality affects file size and visible compression artefacts.
NOTE
Not a full RAW development suite
LokalPix does not provide manual controls for white balance, exposure or lens profiles. A dedicated photo application remains better for controlled RAW development.
FORMAT IN DEPTH
What is DNG?
Technical background for those who want to understand the format.
History and origin
Digital Negative (DNG) was released by Adobe in 2004 as an open RAW standard. The goal: a vendor-neutral format to complement the proprietary RAW formats used by individual camera manufacturers. Canon uses .CR2 or .CR3, Nikon uses .NEF, Sony uses .ARW — DNG, by contrast, is publicly documented and owned by no single company.
Who uses DNG?
Apple stores ProRAW shots (iPhone 12 Pro and later) as DNG files. Google Pixel phones, Leica cameras, many DJI drones, and the mobile version of Adobe Lightroom all use DNG. The format has established itself as an open standard, particularly in smartphone photography.
DNG vs. JPG: the difference
DNG contains unprocessed sensor data at 12–14 bits of colour depth per channel — up to 16,384 brightness levels compared to 256 in JPG. This allows non-destructive corrections to exposure, white balance, and colour after the fact. JPG is a finished, compressed image suited for quick sharing and publication.
What is lost during conversion?
Converting DNG to JPG is irreversible. You lose: the high colour depth (12–14 bit → 8 bit), all RAW processing parameters (exposure and white balance can no longer be adjusted without quality loss), and depth data in ProRAW shots. For archiving, keep your original DNG files.
FAQ
Questions about DNG conversion
Answers about privacy, quality and limitations.
Does my DNG file really stay on my device?
Yes. LokalPix does not upload the image file. RAW decoding and JPG creation run locally using JavaScript, WebAssembly and browser features.
Is Apple ProRAW the same as DNG?
Apple ProRAW uses the industry-standard DNG file format and adds iPhone image processing. ProRAW files therefore use the .dng extension.
Why does the JPG look different from my photo app?
RAW files need development. Different RAW engines may interpret colour, contrast, sharpening and noise reduction differently.
Which JPG quality should I choose?
90 percent is a practical starting point. Lower it for smaller files or raise it when limiting compression loss matters more.
Can I convert several DNG files at once?
Yes. Process up to 20 files in one batch and download multiple results together as a ZIP.
Do all Apple ProRAW files work?
No. Some newer Apple ProRAW DNG files use JPEG XL compression, which the currently bundled local RAW decoder does not support. LokalPix shows a clear error for an unsupported file. Keep the original file.
What are the limits?
Each file may be up to 75 MB. Images above 40 megapixels or 16,384 pixels on either side are rejected to protect browser stability.
Which automatic RAW development does LokalPix use?
The local decoder uses the camera white balance and outputs 8-bit image data for JPG creation. There are no manual controls for exposure, white balance, lens correction, sharpening, or noise reduction.
