Convert BMP to PNG Online — Free & Fast

BMP е некомпресиран и произвежда големи файлове, непрактични за споделяне. Конвертирането на BMP в PNG осигурява компресия без загуба — драматично намалява размера на файла.

Why Convert BMP to PNG?

📉

Уеб споделяне

PNG е много по-малък от BMP при запазване на точно същото качество.

🎨

Прозрачност

PNG поддържа алфа канал — BMP не. Конвертирайте, за да добавите поддръжка на прозрачност.

🌐

Потребителски интерфейси

UI активи като икони и бутони са пакетирани като PNG, не BMP.

🔧

Имейл работен процес

PNG може да бъде прикачен към имейл без крайни ограничения за размер.

Как да конвертирате BMP в PNG?

1
Качете вашия BMP файл

Кликнете на "Избери файл" или плъзнете BMP изображението.

2
Изберете PNG като изходен формат

Изберете "PNG" като желан изходен формат.

3
Конвертирайте файла

Кликнете "Конвертирай сега" за начало на конвертирането от BMP в PNG.

4
Изтеглете PNG файла

След приключване на конвертирането, изтеглете своя PNG файл.

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
  • MIME typeimage/png

Pro tip: PNG без загуба запазва точно същото качество на пикселите като изходния BMP. Спестяването на размер обикновено е 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.

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

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
