Why this pair exists — RW2 is Panasonic's RAW format used in Lumix cameras. Ergo, the ICO route. If you have ended up with a RW2 and need a ICO, the mismatch is almost always about where the image is going next rather than the picture itself. Our server reads the RW2 with ImageMagick, decodes each pixel, and re-writes it as a ICO using defaults tuned for fidelity first and file size second. In practice RW2 is Panasonic's RAW format used in Lumix cameras. On the other end, ICO is the Windows icon container with multiple resolutions packed into one file.
Panasonic RAW RW2
Source formatRW2 is Panasonic Lumix RAW format.
ICO Icon
Target formatICO is the icon file format used for favicons and Windows application icons. A single ICO file can contain multiple image sizes and color depths for different display contexts.
Why convert RW2 to ICO
Both RW2 and ICO describe a grid of pixels — the difference lies in how that grid is compressed, whether transparency is supported, and which software opens it natively. Moving from RW2 to ICO is worth it when the ICO ecosystem is broader for your use case, or when ICO compresses photographs more efficiently than RW2.
HOW TO CONVERT
RW2 → ICO
Drop the RW2 file
Drag and drop or click to upload your RW2. The image is transferred securely over HTTPS and queued for conversion.
Re-encode with ImageMagick
ImageMagick decodes every pixel of the RW2 and writes a matching ICO with sensible default quality settings.
Download the ICO
The converted ICO is ready to download as a single file; both files delete automatically within two hours.
Common Use Cases
Web publishing and CMSes
ICO uploads cleanly to WordPress, Ghost, Webflow and most blogging platforms; many CMSes silently transcode or reject RW2.
Email attachments
Email clients preview ICO inline while RW2 may arrive as an unrecognised attachment on older Outlook or mobile apps.
Social media uploads
Platforms like Instagram, X and Facebook accept ICO natively; RW2 is often rejected or silently converted with unpredictable results.
Design hand-off
Designers shipping assets to developers prefer ICO for faster pipeline imports and consistent display across build tools.
Quality & Compatibility
If ICO is a lossless format (PNG, TIFF, BMP) the output keeps every pixel of the decoded RW2 exactly. If ICO is a lossy codec (JPEG, WebP, HEIC), the encoder re-compresses the image at the quality level you select — default 85 is transparent for photographs, quality 92+ for illustrations with hard edges.
Tips for Best Results
- Keep the original RW2 alongside the ICO output — re-encoding already-lossy images accumulates detail loss on each round.
- If the ICO will be uploaded to a CMS, check whether the platform has a max dimension and downscale once on export rather than letting the CMS resize automatically.
- For thumbnails and avatars, export the ICO at exactly the display size; browsers will otherwise resample and the image may look soft.
Frequently Asked Questions
Frequently Asked Questions
It depends on the codecs involved. If both RW2 and ICO are lossy, the pixels are re-encoded and a small amount of detail is discarded — invisible at default quality settings on photographs. If ICO is lossless (PNG, TIFF, BMP) the output keeps every pixel of the decoded RW2 exactly, but cannot recover detail that RW2 had already compressed away.
Often yes, especially when ICO is lossless. RW2 tuned for efficient web delivery will usually produce smaller files than ICO's default settings. If file size matters, drop the quality in Advanced or pick a more compressed target format instead.
KaijuConverter uploads over HTTPS, processes the image in an isolated container and deletes both the source and the output within two hours. No account is required, file contents are never logged, and we do not use uploads to train any model. For confidential material, the paid plan includes a data-processing agreement.
Secure & Private Conversion
Your files are encrypted during transfer, processed in isolated containers, and automatically deleted within 2 hours. We never read, share, or store your data.
