Edit RW2 Files Online
Open Panasonic Lumix RAW (RW2) files from Panasonic cameras right in your browser — decode, color grade and export JPEG in minutes. Free, no upload, no software to install.
What is a RW2 file?
RW2 is the RAW format produced by Panasonic Lumix S5 II, GH6, G9 II, LX100 II and other Lumix cameras. RW2 keeps the full sensor data from Lumix cameras — including video-oriented bodies whose stills often deserve more editing headroom than JPEG allows.
Because RW2is 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 RW2 file online
- Open OpticRaw and drag your RW2 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 RW2 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 RW2 file gives dramatically better results than editing the camera JPEG — especially for exposure mistakes and tricky light.

Frequently asked questions
Can I open RW2 files online for free?
Yes. OpticRaw decodes RW2 files directly in your browser using LibRaw (WebAssembly) — free, no watermark, no account.
Is my RW2 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 RW2 to JPEG?
Open the RW2 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 RW2?
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 RW2 file?
Never. Editing is non-destructive: the original RAW file stays untouched and you export a separate JPEG or PNG.
