在线将 BMP 转换为 TIFF — 免费快速

BMP is uncompressed and Windows-only — robust, but impractical for most modern needs. Converting BMP to PNG gives you a lossless format that's typically 60–80% smaller, while preserving every pixel perfectly. PNG also adds alpha-channel transparency support that BMP entirely lacks. For any workflow starting with BMP source files — game textures, UI screenshots, or system resources — PNG is the natural next step before editing or publishing.

为什么将 BMP 转换为 TIFF？

📉

60–80% size reduction

PNG compresses BMP files by 60–80% with zero quality loss, making them practical to store and share.

🎨

Add transparency

Convert to PNG, then add alpha-channel transparency in any editor — something BMP can't carry.

🌐

Web-ready

Browsers display PNG natively. BMP is not supported in any web browser — PNG is required.

🔧

Cross-platform

PNG works on Windows, macOS, Linux, iOS, and Android. BMP is effectively Windows-only.

BMP

文件扩展名.bmp
描述BMP (Bitmap) stores uncompressed bitmap digital images independently of the display device. Large file sizes but no quality loss.
相关程序Microsoft Paint, Adobe Photoshop, GIMP, MS Photo Editor
开发者Microsoft
MIME 类型image/bmp

TIFF

文件扩展名.tiff
描述TIFF is a flexible, adaptable format for professional printing, publishing, and photography. Supports lossless compression.
相关程序Adobe Photoshop, GIMP, CorelDRAW, Lightroom
开发者Aldus Corporation (now Adobe)
MIME 类型image/tiff

✅

Pro tip: BMP files often have no DPI metadata. If print size matters, set the correct DPI in your PNG after conversion using any image editor.

BMP vs TIFF：完整格式指南

功能

BMP （源）

TIFF （目标）

🗜️压缩

None

None/LZW/ZIP

🔍透明度

Only in 32-bit BMP via BITMAPV4/V5HEADER alpha channel — inconsistently supported by applications

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

🎬动画

Not supported

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

🎨色彩深度

1-bit monochrome to 32-bit RGBA — most common use is 24-bit (16.7 million colors)

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

📦文件大小

3 MB – 25 MB per image — a 1920×1080 24-bit BMP is approximately 5.9 MB

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

🌐浏览器支持

Technically supported by most browsers but virtually never used on the web due to enormous file sizes

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

BMP

关于 {from} 格式 BMP

BMP (Device-Independent Bitmap) was introduced by Microsoft with the Windows 3.0 SDK in 1990 as the native raster format for Windows. It stores pixel data with zero compression, ensuring perfect reproduction across all hardware. BMP dominated early Windows computing for wallpapers, icons, and application graphics. As the internet grew, its massive file sizes made it impractical for any networked use, displacing it with JPG, PNG, and WebP.

优点

+Zero compression artifacts — the highest possible fidelity for raw storage

+Simple, well-documented format trivial to read/write programmatically

+Universal support across all Windows software and development tools

+Direct pixel data access with no decoding overhead

局限性

−Extremely large files — a 1080p image is ~6 MB vs ~300 KB as JPG

−No practical web use — impractically large for any internet delivery

−Limited support outside Windows ecosystem

−No meaningful advantages over PNG for any modern use case

使用时机

→Legacy Windows applications that exclusively require BMP format

→Automated Windows image processing pipelines as an intermediate format

→System resource files (wallpaper, specific application bitmaps)

→When absolute raw pixel fidelity is needed and file size is irrelevant

提示

•PNG achieves identical lossless quality to BMP at 50–70% smaller file sizes

•Convert to JPG for a 95%+ file size reduction with visually excellent quality

•24-bit BMP and 24-bit PNG are visually identical — PNG is always the better choice

•There are essentially no modern use cases where BMP is preferable to 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
