BMP vs WEBP: Guida completa ai formati

BMP

None

Compressione

WEBP

Lossy+Lossless

BMP

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

Trasparenza

WEBP

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

BMP

Not supported

Animazione

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)

Profondità colore

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

Dimensione file

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

Supporto browser

WEBP

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

Casi d'uso comuni: 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…

Punti di forza

+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

Limitazioni

−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…

Punti di forza

+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

Limitazioni

−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 in WEBP: Quello che devi sapere

Il WebP offre tutto ciò che il BMP non ha: compressione moderna (con e senza perdita), supporto della trasparenza e dimensioni dei file notevolmente più piccole. La conversione da BMP a WebP può ridurre un bitmap non compresso da 6 MB a meno di 200 KB senza perdita di qualità visibile.

Perché convertire BMP in WEBP?

📉

Riduzione dimensioni 90–97%

Il WebP comprime i file BMP del 90–97%, trasformando gigabyte di bitmap in risorse web gestibili.

Formato pronto per il web

I browser visualizzano il WebP nativamente. Il BMP non può essere renderizzato in nessun browser web senza plugin.

🌐

🎨

Senza perdita o con perdita

Scegli WebP senza perdita per preservare i dati pixel esatti del BMP, o con perdita per la massima compressione.

Caricamento istantaneo

I piccoli file WebP si caricano quasi istantaneamente nelle app web, migliorando drasticamente l'esperienza utente.

BMP

Estensione file.bmp
DescrizioneBMP (Bitmap) stores uncompressed bitmap digital images independently of the display device. Large file sizes but no quality loss.
Programmi associatiMicrosoft Paint, Adobe Photoshop, GIMP, MS Photo Editor

WEBP

Estensione file.webp
DescrizioneWebP provides superior lossless and lossy compression for images on the web. WebP images are typically 25-34% smaller than comparable JPEG or PNG files.

Come convertire BMP in WEBP?

Converti il tuo file BMP nel formato WEBP in 3 semplici clic.

Carica il tuo file BMP

Clicca su "Scegli file" o trascina la tua immagine BMP.

Seleziona WEBP come formato di output

Scegli "WEBP" come formato di output dal menu a discesa.

Converti il file

Clicca su "Converti ora" per avviare la conversione da BMP a WEBP.

Scarica il file WEBP

Al termine della conversione, scarica il tuo file WEBP convertito.

💡

Suggerimento: Scegli la codifica WebP senza perdita per preservare i dati pixel esatti del BMP. Usa WebP con perdita solo quando le dimensioni del file più piccole sono più importanti della precisione pixel perfetta.
