将 PNG 转换为 TIFF

TIFF是专业印刷生产、出版和归档工作流程的首选格式。将PNG转换为TIFF将您的图像升级为支持多层数据、无限色深和带有丰富元数据嵌入的无损压缩的格式。

何时将 PNG 转换为 TIFF

🖨️

印前和印刷

胶版印刷工作流程需要TIFF用于CMYK色彩空间和高分辨率输出。

🏛️

档案标准

图书馆和博物馆按照ISO标准使用TIFF作为其数字保存格式。

🎨

高位深

TIFF支持32位HDR和16位色——对于专业图像处理至关重要。

📚

DTP软件

Adobe InDesign、QuarkXPress和专业出版工具完全支持TIFF导入。

PNG vs TIFF：完整格式指南

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

常见使用场景：PNG → TIFF

🖨️ Professional print production📚 Library and archive submissions🎨 Prepress and publishing📸 Photography post-production

⚠️TIFF files will be significantly larger than PNG — expect 3–10× the file size. Always enable LZW or ZIP compression in your TIFF save settings to reduce size without any quality loss.

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

使用时机 PNG

→Logos, icons, and brand marks placed over any background color

→Screenshots where text must remain perfectly sharp

→Images edited in multiple passes (keep as the master file)

→Web UI elements, buttons, icons, and interface assets

提示

•PNG-8 (256 colors) halves the file size of PNG-24 for simple flat-color graphics

•Converting PNG to WebP typically saves ~30% file size with no visible quality change

•Alpha transparency requires PNG-24 or PNG-32 — PNG-8 only supports binary transparency

•Tools like pngquant can reduce PNG size by 50–80% with minimal quality impact

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
