BMP vs WEBP: Hướng dẫn đầy đủ về định dạng

BMP

None

Nén

WEBP

Lossy+Lossless

BMP

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

Độ trong suốt

WEBP

Full 8-bit alpha channel — same capability as PNG, with better compression efficiency

BMP

Not supported

Hoạt ảnh

WEBP

Supported — animated WebP stores multiple frames with per-frame timing data, offering vastly better quality and smaller files than animated GIF

BMP

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

Độ sâu màu

WEBP

24-bit RGB + 8-bit alpha — 16.7 million colors with full alpha transparency

BMP

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

Kích thước tệp

WEBP

25–35% smaller than an equivalent-quality JPEG or PNG — typically 30–80 KB for standard web images

BMP

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

Hỗ trợ trình duyệt

WEBP

Chrome 23+, Firefox 65+, Edge 18+, Safari 14+, Opera 12+. Not supported in Internet Explorer or Safari prior to iOS/macOS in 2020.

Trường hợp sử dụng phổ biến: BMP → WEBP

🌐 Modernizing legacy image archives⚡ Web performance optimization🛒 E-commerce image migration

⚠️Excellent for batch-modernizing old BMP image archives for web use. The file size reduction compared to original BMP is dramatic — typically 95–99% smaller.

Format

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 repro…

Điểm mạnh

+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

Hạn chế

−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

Legacy Windows applications that exclusively require BMP formatAutomated Windows image processing pipelines as an intermediate formatSystem resource files (wallpaper, specific application bitmaps)When absolute raw pixel fidelity is needed and file size is irrelevant

Format

WEBP

Google developed WebP and announced it in 2010 using technology from the VP8 video codec. Initial adoption was Chrome-only, but Firefox added support in 2019 and Apple's Safari 14 followed in 2020 — f…

Điểm mạnh

+25–34% smaller than JPEG/PNG at equal quality — direct page load improvement

+Both lossy and lossless compression modes in a single format

+Full alpha transparency like PNG at significantly smaller file sizes

+Animated WebP replaces GIF with full-color quality and dramatically smaller files

Hạn chế

−Not supported in Internet Explorer or Safari before iOS 14 / macOS Big Sur

−Print shops, Outlook, and Office apps don't accept WebP

−Limited native support in professional desktop imaging software

−Not practical for offline print workflows requiring Photoshop or Lightroom native support

Websites targeting modern browsers (Chrome, Firefox, Edge, Safari 14+)E-commerce and high-traffic sites where image performance impacts conversionsMobile-first apps where bandwidth and load time are criticalReplacing animated GIFs with higher-quality, much smaller animated alternatives

BMP sang WEBP: Những gì bạn cần biết

Tệp BMP rất lớn — bitmap 1920×1080 khoảng 6 MB. Chuyển đổi BMP sang WebP có thể giảm kích thước tệp lên đến 90% với chất lượng hình ảnh xuất sắc.

Tại sao chuyển đổi BMP sang WEBP?

📉

Hiệu suất web

WebP có thể nhỏ hơn BMP đến 90%, giảm đáng kể thời gian tải trang.

Trình duyệt hiện đại

Tất cả trình duyệt hiện đại hỗ trợ WebP gốc.

🌐

🎨

Tối ưu hóa CDN

Tệp WebP nhỏ hơn nghĩa là chi phí băng thông thấp hơn.

Ứng dụng di động

WebP được hỗ trợ gốc trên Android và iOS.
