Convert BMP to PNG Online — Free & Fast

BMP is ongecomprimeerd en produceert grote bestanden die onpraktisch zijn om te delen. BMP naar PNG converteren biedt verliesvrije compressie — vermindert de bestandsgrootte dramatisch.

Why Convert BMP to PNG?

📉

Web delen

PNG is veel kleiner dan BMP met exact dezelfde kwaliteit behouden.

🎨

Transparantie

PNG ondersteunt alfa-kanaal — BMP niet. Converteer om transparantieondersteuning toe te voegen.

🌐

Gebruikersinterfaces

UI-assets zoals pictogrammen en knoppen worden verpakt als PNG, niet BMP.

🔧

E-mailworkflow

PNG kan worden bijgevoegd aan e-mail zonder extreme groottebeperking.

Hoe BMP naar PNG converteren?

Upload uw BMP-bestand

Klik op "Bestand kiezen" of sleep uw BMP-afbeelding.

Selecteer PNG als uitvoerformaat

Kies "PNG" als gewenst uitvoerformaat.

Bestand converteren

Klik op "Nu converteren" om de conversie van BMP naar PNG te starten.

PNG-bestand downloaden

Na voltooiing downloadt u uw geconverteerde PNG-bestand.

BMP

File extension.bmp
DescriptionBMP (Bitmap) stores uncompressed bitmap digital images independently of the display device. Large file sizes but no quality loss.
Associated programsMicrosoft Paint, Adobe Photoshop, GIMP, MS Photo Editor
Developed byMicrosoft
MIME typeimage/bmp

PNG

File extension.png
DescriptionPNG (Portable Network Graphics) is a lossless raster image format that supports transparency. Ideal for graphics, logos, icons, and images that require a transparent background.
Associated programsAdobe Photoshop, GIMP, Microsoft Paint, Preview (Mac)
Developed byPNG Development Group

✅

Pro tip: Verliesvrije PNG behoudt exact dezelfde pixelkwaliteit als de bron-BMP. Groottebesparing is doorgaans 50–70%.

Format Guide

BMP vs PNG: Complete Format Guide

Feature

BMP (source)

PNG (target)

🗜️Compression

None

Lossless

🔍Transparency

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

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

🎬Animation

Not supported

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

🎨Color Depth

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

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

📦File Size

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

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

🌐Browser Support

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

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

🏆Best For

Legacy Windows apps

Graphics, logos, UI

Common Use Cases: BMP → PNG

🌐 Web graphics preparation🎨 Design software import📤 Cross-platform file sharing💾 Lossless size reduction

⚠️This is one of the most recommended BMP conversions — you get identical lossless quality at 50–70% smaller files, plus added transparency support and universal cross-platform compatibility.

BMP

About the 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.

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

When to Use

→Legacy Windows applications that exclusively require BMP format

→Automated Windows image processing pipelines as an intermediate format

→System resource files (wallpaper, specific application bitmaps)

→When absolute raw pixel fidelity is needed and file size is irrelevant

Tips

•PNG achieves identical lossless quality to BMP at 50–70% smaller file sizes

•Convert to JPG for a 95%+ file size reduction with visually excellent quality

•24-bit BMP and 24-bit PNG are visually identical — PNG is always the better choice

•There are essentially no modern use cases where BMP is preferable to PNG

PNG

About the 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.

Strengths

+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

Limitations

−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

When to Use

→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
