Add your RW2 file
Drop one or more .rw2 files onto the converter above, or browse for them. They load into browser memory only — nothing is uploaded, so there is no size-based pricing and no server queue.
Developing a .rw2 camera file into .jpg turns unprocessed sensor data into a finished image any app can open. Free, private, and validated — the file never leaves your browser.
Batch files can each use a different output. Nothing uploads for local conversions.
Working inputs include camera RAW, browser-local audio/video, PDF, CBZ/CBR comics, office documents, ebooks, markup, 3D models, structured text, images, and archives.Developing a .rw2 camera file into .jpg turns unprocessed sensor data into a finished image any app can open. An .rw2 file is a Panasonic Lumix RAW photograph, storing sensor data along with the lens-correction parameters that Micro Four Thirds imaging depends on. A distinctive trait of .rw2 is that its embedded distortion-correction metadata is essentially mandatory: raw converters must apply it to render geometrically correct images from many Lumix lenses.
A .jpg file is a photograph or other continuous-tone image compressed with the JPEG standard, the most widely used image codec ever shipped. Nearly every camera, phone, and website produces or accepts .jpg files, which makes it the default interchange format for photos. For this route the practical draw is opens everywhere, from 1990s software to the newest phone and excellent size-to-quality ratio for photographic content — balanced against every re-save re-compresses the image, so quality erodes across editing generations, which is worth knowing before you commit a large batch.
The practical trigger for this conversion is usually a mismatch: with .rw2, renderers that ignore the correction metadata produce visibly distorted output from certain lenses. Switching to .jpg buys you opens everywhere, from 1990s software to the newest phone, which is why it is the better fit for publishing photographs on websites where file size and universal support matter. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
| Aspect | Panasonic RAW (.rw2) | JPEG image (.jpg) |
|---|---|---|
| Format type | Lossless — every pixel or sample is preserved exactly | Lossy — discards detail it judges invisible to shrink files |
| How it stores data | tIFF-based container with Panasonic-specific tag numbering and the raw mosaic at 12 or 14 bits | compresses 8x8 pixel blocks with a discrete cosine transform followed by quantization, which is where detail is discarded |
| Strongest at | raw workflows for Lumix GH-series video-hybrid and S-series full-frame cameras | publishing photographs on websites where file size and universal support matter |
| Weak spot | renderers that ignore the correction metadata produce visibly distorted output from certain lenses | every re-save re-compresses the image, so quality erodes across editing generations |
| Metadata | eXIF plus Panasonic MakerNotes carry shooting parameters and the crucial lens-correction tables; XMP is sidecar-based in most editing workflows | carries EXIF (camera settings, GPS, orientation), XMP, and IPTC records in APPn marker segments, plus embedded ICC color profiles and thumbnails |

Select .jpg in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if JPG is selectable, the route is real and validated.
Press Convert. A LibRaw WebAssembly decoder demosaics the sensor data in your browser and renders a developed image ready for export.
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid JPG file. Outputs keep the original filename with the .jpg extension.
Some. Since rw2 is lossless-oriented and jpg is lossy-oriented, the encoder will discard detail it judges least visible; the quality slider controls how aggressive that is. Keep the original .rw2 if you may need a pristine master later.
Yes — the .rw2 file is processed inside your browser tab and never uploaded. A LibRaw WebAssembly decoder demosaics the sensor data in your browser and renders a developed image ready for export. Close the tab and the file is gone from memory.
JPEG is supported by every mainstream operating system, browser, image editor, and printer driver in use today. It decodes natively on iOS, Android, Windows, macOS, and Linux without any add-on codecs, and every browser has rendered it since the format reached the web in the 1990s.
Smaller, usually dramatically so — that is the main reason this route exists. The quality slider trades size against fidelity; the default sits at the point where most people cannot spot the difference.
In .rw2, eXIF plus Panasonic MakerNotes carry shooting parameters and the crucial lens-correction tables; XMP is sidecar-based in most editing workflows. Re-encoding through the browser pipeline does not carry embedded metadata into the output, which doubles as a privacy scrub — check the exported file if you specifically need tags preserved.
