Camera RAW inspector and preview

• Choose a supported camera RAW file up to 64 MiB.
• Select common metadata or existing embedded preview.
• Inspect locally and download the result. Preview extraction fails explicitly if no supported preview exists.

Inspect a Nikon NEF camera model and dimensions, or extract its existing camera JPEG preview.

• Local LibRaw 0.22.2 stable decoder. Camera model and compression determine support, not filename extension. Tested camera fixtures include Canon EOS 350D CR2, Nikon D2H NEF, Sony ILCE-7S ARW and a controlled uncompressed Bayer DNG. Other models may work but are not guaranteed.
• Input at most 64 MiB, 40 megapixels and 16,384 pixels per side; developed output at most 16 megapixels. The native worker has a 512 MiB memory ceiling, a 256 MiB RAW allocation setting and a 120-second overall deadline. Some mobile devices may have less memory available.
• First RAW image only. Headerless sensor dumps, ordinary raster images, Adobe DNG SDK/GoPro/X3F-dependent formats and JPEG XL or VC-5 compressed DNG are unsupported. Optional RawSpeed and professional development plug-ins are absent.
• Decoder assets download on first use; the selected file stays in your browser. CDDL-selected source, notices, build instructions and relocatable archives are supplied with the decoder.
• Metadata mode reads selected common camera, dimension, exposure and white-balance fields; it is not an exhaustive EXIF/GPS audit or full RAW integrity test. Zero exposure fields may mean unavailable, and the stored timestamp has no independently verified timezone.
• Embedded-preview mode extracts the existing JPEG byte stream or encodes a stored eight-bit bitmap as PNG. It does not develop sensor data. Preview is limited to 16 MiB and 16 megapixels; absent, unsupported or corrupt previews fail explicitly. Extracted JPEG bytes may retain metadata; the on-page preview uses stored orientation and excludes source metadata.
