Konvertera PNG till BMP

BMP är Windows inbyggda bitmappformat för OS-tapeter, ikoner och äldre programvara. Att konvertera PNG till BMP producerar okomprimerade råa pixeldata.

Varför konvertera PNG till BMP?

🎮

Inbyggda Windows-appar

BMP är OS-nivåformat för Windows tapeter, markörer och systemresurser.

🖥️

Retro-spelutveckling

Klassiska spelmotorer kräver BMP för sprites, tilesets och startskärmar.

⚙️

Vetenskaplig avbildning

Laboratorie- och medicinsk bildprogramvara kräver okomprimerad BMP.

🔧

Direkt pixelåtkomst

BMPs enkla struktur möjliggör direkt minnesåtkomst utan avkodare.

PNG

Hur konverterar man PNG till BMP?

Konvertera din PNG-fil till BMP-format på 3 enkla steg.

Step 01

Ladda upp din PNG-fil

Klicka på "Välj fil" eller dra din PNG-bild till uppladdningsytan.

Step 02

Välj BMP som utdataformat

Välj "BMP" som önskat utdataformat.

Step 03

Konvertera filen

Klicka på "Konvertera nu" för att starta konverteringen av PNG till BMP.

Step 04

Ladda ner BMP-filen

När konverteringen är klar, ladda ner din konverterade BMP-fil.

💡

Tip: BMP-filer kan vara 5–10× större än motsvarande PNG. Kontrollera att målsystemet har tillräckligt lagringsutrymme.

Funktion

PNG (källa)

BMP (mål)

🗜️Komprimering

Lossless

None

🔍Transparens

Full 8-bit alpha channel — each pixel can be any opacity level from fully transparent (0) to fully opaque (255)

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

🎬Animation

Not in standard PNG; APNG (Animated PNG) is a non-standard extension with limited, inconsistent support

Not supported

🎨Färgdjup

24-bit RGB (16.7M colors) or 32-bit RGBA (16.7M colors + full alpha); up to 48-bit for professional workflows

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

📦Filstorlek

100 KB – 10 MB — significantly larger than JPG for photographic content

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

🌐Webbläsarstöd

Universal — all modern browsers, operating systems, and devices including IE7+

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

⚠️Converting PNG to BMP removes all compression and dramatically increases file size — a 300 KB PNG can become a 3–5 MB BMP. Only use this conversion when the target system specifically requires BMP input.

PNG

Om {from}-formatet PNG

PNG was created in 1996 as a free, patent-unencumbered alternative to GIF after Unisys enforced its LZW compression patent. The PNG Development Group introduced full-color support, genuine alpha transparency, and superior lossless compression. It quickly became the web standard for logos, UI elements, and any image requiring a transparent background — a role it dominates to this day.

Styrkor

+Lossless — every pixel preserved with zero compression artifacts

+Full 8-bit alpha channel for smooth, semi-transparent edges

+Ideal for text, logos, and graphics where sharpness is non-negotiable

+Unlimited re-saves without any quality degradation whatsoever

+Supports up to 48-bit color depth for professional color workflows

Begränsningar

−3–5× larger than JPG for photographic content

−No native animation support in standard PNG

−Slower to load than WebP for equivalent image content

−Not practical for very high-resolution photographs at web scale

När du ska använda

→Logos, icons, and brand marks placed over any background color

→Screenshots where text must remain perfectly sharp

→Images edited in multiple passes (keep as the master file)

→Web UI elements, buttons, icons, and interface assets

Tips

•PNG-8 (256 colors) halves the file size of PNG-24 for simple flat-color graphics

•Converting PNG to WebP typically saves ~30% file size with no visible quality change

•Alpha transparency requires PNG-24 or PNG-32 — PNG-8 only supports binary transparency

•Tools like pngquant can reduce PNG size by 50–80% with minimal quality impact

BMP

Om {from}-formatet 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 reproduction across all hardware. BMP dominated early Windows computing for wallpapers, icons, and application graphics. As the internet grew, its massive file sizes made it impractical for any networked use, displacing it with JPG, PNG, and WebP.

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

När du ska använda

→Legacy Windows applications that exclusively require BMP format
