TIFF vs GIF：完全なフォーマットガイド

TIFF

None/LZW/ZIP

圧縮

GIF

Lossless (LZW)

TIFF

Supported — extra alpha channels with full precision, stored as associated or unassociated alpha

透明度

GIF

Binary 1-bit transparency only — each pixel is either fully transparent or fully opaque (no partial transparency)

TIFF

Not natively supported; multi-page TIFF stores multiple images but without animation timing data

アニメーション

GIF

Core feature — stores multiple frames with individual display timings, loop count, and optional per-frame color palettes

TIFF

Up to 64-bit (16-bit per channel RGBA), including CMYK, Lab, and specialized color space support

色深度

GIF

8-bit only — maximum 256 colors per frame (each frame may have its own 256-color palette)

TIFF

5 MB – 100 MB+ per image — a 24MP camera image is typically 60–80 MB as uncompressed TIFF

ファイルサイズ

GIF

10–200 KB for static GIFs; 0.5 MB – 20 MB for animated GIFs

TIFF

Not supported in any web browser — cannot be displayed on web pages without prior conversion

ブラウザサポート

GIF

Universal — all browsers including IE5, all operating systems, all mobile devices, all social media platforms

TIFF

Professional printing

最適な用途

GIF

Animations, icons

TIFF

TIFF was developed by Aldus Corporation in 1986 to standardize images scanned for desktop publishing. Its flexible, extensible container supports multiple compression options and bit depths within the…

長所

+16-bit and 32-bit per channel for HDR photography and scientific imaging

+Multiple compression options: balance quality against file size as needed

+Industry standard for professional printing, prepress, and photography archiving

+CMYK and Lab color space support for accurate print production

制限事項

−Enormous file sizes — impractical for web delivery or consumer sharing

−No browser support — must convert before any web display

−Slow to open and process even in professional software

−Incompatible with consumer applications, email clients, and mobile devices

Format

GIF

GIF was invented by CompuServe engineer Steve Wilhite in 1987 for transmitting images over slow modem connections. Its 256-color limit reflected the monitor technology of that era. A 1990s patent disp…

長所

+Universal support on every device and platform ever made

+Animation support with per-frame timing and seamless looping

+Excellent LZW compression for images with large areas of solid color

+Binary transparency works cleanly for logos on solid backgrounds

制限事項

−Hard 256-color limit causes visible banding and dithering on photographs

−Binary transparency only — no anti-aliased edges on variable backgrounds

−Animated GIFs are very large compared to animated WebP or MP4 video

−Color quantization permanently destroys photographic color quality

TIFF を GIF に変換

PNG is TIFF's natural counterpart for digital publishing — lossless, but web-friendly and universally displayable. Converting TIFF to PNG retains all the color and quality of your professional file while producing an image that any browser, email client, or operating system can display. PNG's compression algorithm produces files far smaller than TIFF, making it the go-to conversion for photographers and designers moving from print to web workflows.

なぜ TIFF を GIF に変換するのか？

✓
Web display Browsers can't display TIFF. PNG is the lossless format of choice for web publishing.
✓
Email and messaging PNG attaches and displays in every email client and messaging app without issues.
✓
Presentations PowerPoint, Keynote, and Google Slides embed PNG seamlessly at full quality.
✓
Digital archiving For documents under 50 MB, PNG provides an excellent lossless archive format accessible everywhere.
