Edit DNG Files Online
Open Digital Negative (DNG) files from Adobe (universal) cameras right in your browser — decode, color grade and export JPEG in minutes. Free, no upload, no software to install.
What is a DNG file?
DNG is the RAW format produced by Leica, Ricoh GR, DJI drones, and smartphones — Google Pixel, Samsung Expert RAW, iPhone ProRAW exports. DNG is the open RAW standard, so it is the most common RAW file from phones and drones — and the easiest way to move RAW between apps.
Because DNGis a RAW format, most image viewers and web tools can't open it. OpticRaw decodes it with LibRaw — the same engine used by professional desktop software — compiled to WebAssembly so it runs locally in your browser.
How to edit a DNG file online
- Open OpticRaw and drag your DNG file into the window.
- Wait a few seconds while the RAW is decoded (your camera's white balance is applied as the starting point).
- Edit with Lightroom-style tools: exposure, tone curve, HSL color mixer, color grading wheels, masking brush, crop & straighten.
- Click Export to save a full-resolution JPEG or PNG.
Why edit DNG instead of JPEG?
RAW keeps the full sensor data: highlights you can pull back, shadows you can lift cleanly, and white balance you can change after the fact. Editing the DNG file gives dramatically better results than editing the camera JPEG — especially for exposure mistakes and tricky light.
Also works with other RAW formats

Frequently asked questions
Can I open DNG files online for free?
Yes. OpticRaw decodes DNG files directly in your browser using LibRaw (WebAssembly) — free, no watermark, no account.
Is my DNG file uploaded to a server?
No. The file is decoded and edited entirely on your device. It never leaves your computer.
How do I convert DNG to JPEG?
Open the DNG file, make any adjustments you want (or none), then click Export and choose JPEG. You get a full-resolution JPEG in seconds.
Do I need Lightroom or Photoshop to edit DNG?
No. This editor gives you Lightroom-style tools — tone curve, HSL mixer, color grading wheels, masking, crop — right in the browser.
Does editing change my original DNG file?
Never. Editing is non-destructive: the original RAW file stays untouched and you export a separate JPEG or PNG.
