BMP vs WEBP: Guia completa de formats

BMP

None

Compressió

WEBP

Lossy+Lossless

BMP

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

Transparència

WEBP

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

BMP

Not supported

Animació

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)

Profunditat de color

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

Mida del fitxer

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

Suport del navegador

WEBP

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

Casos d'ús comuns: 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…

Punts forts

+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

Limitacions

−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…

Punts forts

+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

Limitacions

−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 a WEBP: El que necessiteu saber

Els fitxers BMP són enormes — un mapa de bits 1920×1080 és d'uns 6 MB. Convertir BMP a WebP pot reduir la mida del fitxer fins al 90% amb una qualitat visual excel·lent.

Per què convertir BMP a WEBP?

📉

Rendiment web

El WebP pot ser un 90% més petit que el BMP, reduint dramàticament el temps de càrrega de la pàgina.

Navegadors moderns

Tots els navegadors moderns suporten WebP de manera nativa.

🌐

🎨

Optimització de CDN

Els fitxers WebP més petits signifiquen costos de CDN més baixos.

Aplicacions mòbils

El WebP és suportat de manera nativa a Android i iOS.
