Need help?How to Convert RW2 to PNG Online
- Upload Your RW2 File: Drag and drop or click "Choose Files" to add Panasonic Lumix .rw2 photos straight from the camera card. Batch is supported — queue several RW2 frames from the same shoot in one pass.
- Pick Quality Preset: Default is "Very High (Recommended)". Choose "Highest" to keep every tonal step from the 12- or 14-bit sensor data, "High" or "Medium" to trim PNG file size, or switch to "Specific file size" (default 8 MB) when you need to hit an upload cap.
- Set Resolution and Compression (Optional): Keep the original sensor resolution, pick a preset (144p–4320p), scale by percentage, or type exact width × height with aspect-ratio lock. Under PNG-specific options, adjust the deflate "Compression level" (default 6) for smaller files or "Compression speed" (default 4) for faster encoding — both are fully lossless.
- Convert and Download: Click "Convert" and download a single PNG or grab the full set as a ZIP. Files process in your browser session — no sign-up, no watermark, no Panasonic software required.
Why Convert RW2 to PNG?
RW2 is Panasonic's proprietary RAW container, used across the Lumix line — Micro Four Thirds bodies (GH6, GH5 II, G9 II), full-frame L-Mount bodies (S5 II, S1R, S1H), and compact LX/FZ models. The format is TIFF-based and stores unprocessed 12- or 14-bit sensor data plus EXIF, white balance, and lens-correction metadata. That makes it ideal for editing but means almost nothing outside Lightroom, Capture One, RawTherapee, darktable, or SilkyPix can display it. PNG (W3C/IETF specification, lossless deflate compression, up to 16-bit per channel with optional alpha) is the natural delivery target when you want a fully editable, universally viewable still.
- Send proofs to clients without RAW software — most reviewers can't open .rw2; PNG renders in any browser, Slack preview, or email client without plugins.
- Archive a flattened render alongside the RAW — keep the RW2 as the negative for future re-edits, and the PNG as a "what it looked like at delivery" reference that won't drift when you update Lightroom presets.
- Web publishing where JPEG artifacts are unacceptable — product shots with fine text, screenshots of camera menus, or graphic overlays benefit from PNG's lossless compression instead of JPEG's 8x8 DCT blocks.
- Print-ready handoff with transparency — PNG supports an alpha channel, so a masked-out subject from your Lumix shoot drops onto a layout without a white halo.
- Stock library or platform upload — Behance, Dribbble, and many CMS systems reject .rw2 outright; PNG is on the accepted list everywhere.
- Forensic / scientific imaging — when you need pixel-exact reproduction of the sensor render with no recompression on subsequent saves, PNG's lossless deflate is the right container.
RW2 vs Other RAW Formats — Quick Comparison
| Property | RW2 (Panasonic) | DNG (Adobe) | CR3 (Canon) | NEF (Nikon) |
|---|---|---|---|---|
| Container basis | TIFF-based | TIFF/EP-based, open spec | ISO BMFF (different from CR2) | TIFF-based |
| Vendor lock-in | Panasonic-only | Open, multi-vendor | Canon-only | Nikon-only |
| Embedded lens corrections | Yes (proprietary) | Yes (when written by camera) | Yes | Yes |
| Bit depth | 12 or 14-bit | Up to 16-bit | 14-bit (typical) | 12 or 14-bit |
| Universal viewer support | Low | Medium | Low | Low |
A common workflow question: should you convert RW2 to DNG for archiving? Adobe's DNG converter is free and DNG is an open spec, but the conversion drops some Panasonic-specific metadata. For a flat deliverable instead, PNG is simpler — it's the lingua franca of lossless raster.
PNG Quality and Compression Guide
| Setting | What it controls | When to pick it |
|---|---|---|
| Quality Preset: Highest | Maximum bit depth retained from RW2 | Archival, print, color grading downstream |
| Quality Preset: Very High | Default, near-lossless render | General delivery — the safe choice |
| Quality Preset: Medium / Low | Reduces effective bit depth | Email proofs, draft thumbnails |
| Specific file size (e.g., 8 MB) | Targets a byte cap, scales internally | Upload to size-capped platforms |
| Compression level 1–9 | Deflate effort (always lossless) | Higher = smaller PNG, slower encode |
| Compression speed 1–9 | CPU tradeoff for encoder | Lower = faster encode, slightly larger PNG |
PNG is always lossless — changing the compression level or speed never throws away pixel data, only changes how aggressively the encoder hunts for redundancy.
Frequently Asked Questions
Do I need SilkyPix or Panasonic PHOTOfunSTUDIO installed to convert RW2?
No. XConvert decodes the RW2 container in-browser, so you don't need SilkyPix Developer Studio (the editor Panasonic bundles with new bodies), PHOTOfunSTUDIO, or Adobe Camera Raw on your machine. The same applies to Lumix bodies whose .rw2 files your installed Lightroom version is too old to open — the converter doesn't depend on your local Camera Raw version.
How is converted PNG different from the in-camera JPEG my Lumix already saved?
The Lumix-generated JPEG is an 8-bit lossy render with picture-style, sharpening, and noise reduction baked in by the camera firmware. Converting from RW2 lets you start from the unprocessed 12- or 14-bit sensor data and produce a lossless PNG — typically 3–5x larger than the JPEG, but with no DCT block artifacts and full editing latitude before encode.
Will my PNG be 8-bit or 16-bit?
XConvert renders to standard 8-bit-per-channel PNG by default, which matches what every browser, Slack, email client, and CMS expects. PNG itself supports 16-bit per channel (per the W3C PNG spec), but very few delivery contexts can display it correctly, so 8-bit is the practical target. If you need 16-bit precision for color grading, keep the RW2 as your master and use RW2 to TIFF instead.
Why is my PNG so much larger than I expected?
PNG is lossless, so a 24-megapixel Lumix shot can land at 30–80 MB depending on scene complexity (smooth skies compress well; fine foliage and noise do not). If size is a problem, drop to "Specific file size", scale by percentage, or convert to JPG via RW2 to JPG for typical web use.
Does the converter preserve EXIF metadata — shutter speed, ISO, lens, GPS?
Yes, EXIF tags written by the Lumix body are carried through to the PNG (PNG stores EXIF in an eXIf chunk). White balance and lens-correction profiles that are RW2-specific are baked into the rendered pixels rather than preserved as editable metadata, since PNG isn't a RAW format.
Which Panasonic cameras produce RW2 files?
The format is used across the Lumix lineup — DC-G/GH/GX (Micro Four Thirds), DC-S (full-frame L-Mount), DMC-LX/FZ (compact and bridge), and current bodies like the GH6, S5 IIX, and G9 II. If your Panasonic body has a "RAW" or "RAW+JPEG" mode, the file it writes to the SD card is .rw2.
Can I batch-convert a full shoot at once?
Yes, queue multiple .rw2 files in a single upload and download them individually or as a ZIP. Each file is rendered independently, so a corrupt frame in the middle of the batch won't fail the rest.
What's the difference between RW2 and DNG, and should I convert RW2 to DNG instead?
DNG (Adobe Digital Negative) is an open RAW container — many photographers convert Panasonic RW2 to DNG for long-term archiving in case Panasonic's proprietary tags become unreadable in future software. DNG keeps the RAW workflow; PNG ends it. If you want a deliverable, pick PNG (or JPG). If you want a future-proof RAW master, use Adobe's free DNG Converter.
Are my files private — does the converter upload them to a server?
XConvert processes files in your browser session and does not retain originals beyond that session. Sensor data from your shoot stays under your control, which matters if the .rw2 contains GPS coordinates or unreleased work.
