JPG vs BMP: Guida completa ai formati

JPG

Lossy

Compressione

BMP

None

JPG

Not supported — transparent areas always render as solid white or the specified matte color

Trasparenza

BMP

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

JPG

Not supported

Animazione

BMP

Not supported

JPG

24-bit (8 bits per channel: RGB) — up to 16.7 million colors

Profondità colore

BMP

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

JPG

50 KB – 5 MB per image depending on resolution and quality setting

Dimensione file

BMP

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

JPG

Universal — all browsers, all operating systems, all devices including IE6 and older smartphones

Supporto browser

BMP

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

JPG

Photos, web images

Ideale per

BMP

Legacy Windows apps

Casi d'uso comuni: JPG → BMP

🖥️ Windows wallpaper format⚙️ Legacy Windows software🔧 Industrial machine input📟 Embedded display systems

⚠️BMP output will be 5–15× larger than the source JPG. Unless a legacy system specifically requires BMP, PNG provides the same lossless quality at a fraction of the file size.

Format

JPG

Standardized in 1992 by the Joint Photographic Experts Group, JPEG became the internet's dominant image format through the 1990s. Its DCT compression made digital photography practical for early web a…

Punti di forza

+Smallest file sizes for photographs (10:1 to 20:1 compression ratio)

+Universal compatibility across every device, software, and platform

+Embeds EXIF metadata (GPS, camera settings, date/time)

+Adjustable quality/size trade-off at save time

Limitazioni

−Lossy — permanently discards image data with every save

−No transparency — backgrounds are always solid

−Visible block artifacts on sharp edges, text, and high-contrast areas

−Quality degrades with each re-save (generational quality loss)

Sharing photographs on social media, email, or blogsCamera images where file size matters more than pixel perfectionWeb page photos where page load speed is the priorityAny context requiring maximum cross-device and software compatibility

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

Converti JPG in BMP

Il BMP è il formato bitmap fondamentale di Windows, utilizzato nativamente dal sistema operativo per sfondi, icone e software legacy. La conversione da JPG a BMP rimuove tutta la compressione per produrre dati pixel grezzi — la rappresentazione di immagine più semplice possibile.

Quando convertire JPG in BMP

⚙️

Windows nativo

Il BMP è il formato a livello OS per gli sfondi Windows, i cursori personalizzati e le risorse di sistema.

🎮

Sviluppo di giochi retrò

I motori di gioco classici come RPG Maker richiedono BMP per sprite, tileset e schermate iniziali.

🔬

Imaging scientifico

Il software di laboratorio e di imaging medico richiede BMP non compresso per l'elaborazione precisa a livello di pixel.

🛠️

Accesso diretto ai pixel

La struttura semplice del BMP consente l'accesso diretto alla memoria senza un decoder — veloce per l'uso in tempo reale.

JPG vs BMP — Confronto tra formati

Proprietà	JPG (input)	BMP (output)

ℹ️ Important note

I file BMP possono essere 10–20 volte più grandi dei file JPG equivalenti. Verifica che il sistema di destinazione abbia spazio di archiviazione sufficiente prima di convertire in batch grandi librerie di immagini in BMP.
