TIFF vs PNG：完整格式指南

功能	TIFF （源）	PNG （目标）
压缩	None/LZW/ZIP	Lossless
透明度	Supported — extra alpha channels with full precision, stored as associated or unassociated alpha	Full 8-bit alpha channel — each pixel can be any opacity level from fully transparent (0) to fully opaque (255)
动画	Not natively supported; multi-page TIFF stores multiple images but without animation timing data	Not in standard PNG; APNG (Animated PNG) is a non-standard extension with limited, inconsistent support
色彩深度	Up to 64-bit (16-bit per channel RGBA), including CMYK, Lab, and specialized color space support	24-bit RGB (16.7M colors) or 32-bit RGBA (16.7M colors + full alpha); up to 48-bit for professional workflows
文件大小	5 MB – 100 MB+ per image — a 24MP camera image is typically 60–80 MB as uncompressed TIFF	100 KB – 10 MB — significantly larger than JPG for photographic content
浏览器支持	Not supported in any web browser — cannot be displayed on web pages without prior conversion	Universal — all modern browsers, operating systems, and devices including IE7+
最适合	Professional printing	Graphics, logos, UI

⚠️16-bit TIFF will typically convert to 8-bit PNG in standard conversion workflows. If deep color preservation is required, configure your conversion tool to specifically output 16-bit PNG.

TIFF

关于 {from} 格式 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 same format. Adobe acquired Aldus in 1994 and maintains the TIFF specification today. TIFF became the definitive professional standard for photography, medical imaging, GIS mapping, and archival digitization requiring maximum data fidelity.

优点

+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

+Multi-page storage for contact sheets, scanned documents, and multi-frame data

局限性

−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

使用时机 TIFF

→Professional photography archiving and long-term preservation

→Print production workflows requiring CMYK or 16-bit color depth

→Medical, scientific, or GIS imaging requiring maximum data precision

→When a print shop or institutional client specifically requires TIFF format

提示

•Use LZW or ZIP compression in TIFF to reduce file size 30–50% with zero quality loss

•Always work in 16-bit TIFF for HDR photo retouching — it preserves tonal detail

•Convert to JPG, PNG, or WebP before any web publishing

•Keep TIFF as your archival master and export separate optimized versions for other uses

PNG

关于 {from} 格式 PNG

PNG was created in 1996 as a free, patent-unencumbered alternative to GIF after Unisys enforced its LZW compression patent. The PNG Development Group introduced full-color support, genuine alpha transparency, and superior lossless compression. It quickly became the web standard for logos, UI elements, and any image requiring a transparent background — a role it dominates to this day.

优点

+Lossless — every pixel preserved with zero compression artifacts

+Full 8-bit alpha channel for smooth, semi-transparent edges

+Ideal for text, logos, and graphics where sharpness is non-negotiable

+Unlimited re-saves without any quality degradation whatsoever

+Supports up to 48-bit color depth for professional color workflows

局限性

−3–5× larger than JPG for photographic content

−No native animation support in standard PNG

−Slower to load than WebP for equivalent image content

−Not practical for very high-resolution photographs at web scale
