CIN to WEBP Converter

CIN (Cineon) is a 10-bit logarithmic image format Kodak built in the early 1990s to represent scanned film frames for digital effects work.

Kodak developed the Cineon system to bridge physical film and digital compositing: scan a negative, edit or add effects digitally, then record the result back onto film without a visible generation loss. To make that round-trip work, the Cineon file format stores each pixel as a 10-bit logarithmic value that mirrors film density rather than a straight linear brightness — the same encoding scheme film stock itself uses — so highlights that would clip in an ordinary 8-bit format stay recoverable. The Cineon product line was discontinued in the late 1990s, but the file format it introduced lived on as the direct basis for DPX, the SMPTE-standardized format that replaced it in most modern VFX pipelines.

WEBP is Google's web-focused image format, offering both lossy and lossless modes plus transparency in one file type.

Google introduced WebP in 2010 to tackle a specific problem: the average web page was (and still is) dominated by image weight, and neither JPEG nor PNG alone could losslessly compete on both photos and graphics. WebP borrows compression techniques from video codecs to squeeze photographic images noticeably smaller than JPEG at the same visual quality, while its lossless mode competes with PNG for graphics — all while still supporting transparency and even simple animation in one container. Adoption was slow at first, but every major browser now supports it natively, which is why so many websites quietly serve WebP images today to cut load times.
