JPEG vs BMP: Complete Format Guide

JPEG

Lossy

Compression

BMP

None

JPEG

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

Transparency

BMP

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

JPEG

Not supported

Animation

BMP

Not supported

JPEG

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

Color Depth

BMP

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

JPEG

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

File Size

BMP

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

JPEG

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

Browser Support

BMP

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

JPEG

Photos, web images

Best For

BMP

Legacy Windows apps

Common Use Cases: JPEG → 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

JPEG

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…

Strengths

+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

Limitations

−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…

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

Convert JPEG to BMP Format

BMP er Windows' innebygde bitmapformat som OS bruker for bakgrunner, ikoner og eldre programvare. Konvertering av JPG til BMP fjerner all komprimering.

When to Convert JPEG to BMP

⚙️

Windows innebygd

BMP er OS-nivåformatet for bakgrunner og egendefinerte pekere.

🎮

Retro-spillutvikling

Klassiske spillmotorer som RPG Maker krever BMP for sprites og tilesets.

🔬

Vitenskapelig avbildning

Laboratorium- og medisinsk programvare krever ukomprimert BMP.

🛠️

Direkte pikselaksess

BMPs enkle struktur muliggjør direkte minnetilgang.

JPEG vs BMP — Format Comparison

Property	JPEG (input)	BMP (output)
Format type	Raster	Raster

ℹ️ Important note

BMP-filer kan være 10–20× større enn tilsvarende JPG-er.
