JPEG vs BMP: Komplett formatguide

JPEG

Lossy

Komprimering

BMP

None

JPEG

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

Transparens

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

Färgdjup

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

Filstorlek

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

Webbläsarstöd

BMP

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

JPEG

Photos, web images

Legacy Windows apps

Vanliga användningsfall: 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…

Styrkor

+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

Begränsningar

−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…

Styrkor

+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

Begränsningar

−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

Konvertera JPEG till BMP

BMP är Windows inbyggda bitmappformat som OS använder för tapeter, ikoner och äldre programvara. Att konvertera JPG till BMP tar bort all komprimering.

När man ska konvertera JPEG till BMP

⚙️

Windows inbyggt

BMP är OS-nivåformat för tapeter och anpassade markörer.

🎮

Retro-spelutveckling

Klassiska spelmotorer som RPG Maker kräver BMP för sprites och tilesets.

🔬

Vetenskaplig avbildning

Laboratorie- och medicinsk bildprogramvara kräver okomprimerad BMP.

🛠️

Direkt pixelåtkomst

BMPs enkla struktur möjliggör direkt minnesåtkomst utan avkodare.

JPEG vs BMP — Formatjämförelse

Egenskap	JPEG (input)	BMP (output)
Format type	Raster	Raster
Compression	Lossy	None
Transparency	No	No
Best used for	Photos, web images	Legacy Windows apps

ℹ️ Important note

BMP-filer kan vara 10–20× större än motsvarande JPG. Kontrollera att målsystemet har tillräckligt utrymme.
