CIN vs WEBP
Kodak Cineon と WebP Image を徹底比較 — ファイルサイズ、品質、互換性、そして用途に応じた最適なフォーマットの選び方を解説します。
Kodak Cineon
Raster & Vector ImagesCineon is a digital film format developed by Kodak for scanning and recording motion picture film. It uses logarithmic encoding to capture the full density range of film negative, preserving maximum tonal detail for post-production grading.
CIN ファイルについてWebP Image
Raster & Vector ImagesWebP is a modern image format developed by Google that provides superior lossless and lossy compression. Files are typically 25-35% smaller than equivalent JPEG or PNG images at the same visual quality.
WEBP ファイルについて長所の比較
CIN 長所
- 10-bit log color preservation.
- Film-scanning archival standard.
- DPX-compatible.
WEBP 長所
- Smaller file sizes than JPEG, PNG, and GIF at equivalent visual quality.
- Single format for lossy photos, lossless graphics, transparency, and animation.
- Full alpha channel support with smaller files than PNG.
- Now universally supported in all modern browsers.
- Open-source reference implementation (libwebp) by Google.
制限・弱点
CIN 制限・弱点
- Legacy — DPX is the modern choice.
- No compression.
- Niche tooling.
WEBP 制限・弱点
- Some older software and image editors still don't read WebP natively.
- Max dimensions are 16,383 × 16,383 — lower than JPEG or PNG.
- Print workflows rarely support WebP (no CMYK, limited color management).
- Editing tools are less mature than JPEG/PNG; round-tripping can lose quality.

よくある 質問
CIN (Kodak Cineon) is an image format used to store raster graphics — a two-dimensional grid of pixels describing a picture. It is part of the raster & vector images family and designed around a specific trade-off between file size, visual fidelity, and feature support (transparency, colour depth, compression type). Photographers, web designers, and content creators choose CIN when its particular strengths match the publishing target.

Most desktop photo viewers (Windows Photos, macOS Preview, GIMP, Photoshop, Affinity Photo) open CIN natively. On mobile, iOS Photos and Google Photos display CIN in the gallery when supported by the OS. If the format is rare or new, convert to JPG or PNG first — both are universally readable — using our CIN to JPG or CIN to PNG converter.

Upload the CIN to KaijuConverter and pick a target format (JPG, PNG, WebP, HEIC, TIFF, BMP, SVG, PDF). The conversion runs in the browser via ImageMagick and returns a download in seconds. No account or installation required; both input and output delete automatically within two hours.
It depends on the task. JPG is the smallest file size for photographs; PNG is lossless with transparency; CIN has its own niche that may favour colour depth, animation, or encoding efficiency over one or both of those. For the final web publish, test all three and measure file size plus visible quality on real content.
