BMP vs WEBP: Complete Format Guide

BMP

None

Compression

WEBP

Lossy+Lossless

BMP

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

Transparency

WEBP

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

BMP

Not supported

Animation

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)

Color Depth

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

File Size

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

Browser Support

WEBP

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

Common Use Cases: 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…

Strengths

+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

Limitations

−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…

Strengths

+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

Limitations

−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 to WEBP: What You Need to Know

BMP-filer er enorme — en 1920×1080 bitmap er ca. 6 MB. Konvertering av BMP til WebP kan redusere filstørrelsen med 90% med utmerket visuell kvalitet.

Why Convert BMP to WEBP?

📉

Webytelse

WebP kan være 90% mindre enn BMP, noe som dramatisk reduserer sideinnlastingstid.

Moderne nettlesere

Alle moderne nettlesere støtter WebP innebygd.

🌐

🎨

CDN-optimalisering

Mindre WebP-filer betyr lavere båndbreddekostnader.

Mobilapper

WebP støttes innebygd på Android og iOS.

BMP

File extension.bmp
DescriptionBMP (Bitmap) stores uncompressed bitmap digital images independently of the display device. Large file sizes but no quality loss.
