Quick Answer: How to Convert PNG to BMP
PNG is Portable Network Graphics — lossless images with full alpha transparency. BMP is Windows Bitmap — the raw, uncomplicated pixel grid. Converting between them re-encodes the media with BMP's compression model, so output quality depends on the settings you pick in the converter. Run it free at practicalwebtools.com/convert/image/png-to-bmp: drop in your PNG, adjust settings if you like, and download the BMP — no signup, no upload, everything stays on your device.
How to Convert PNG to BMP Online
- 1
Add your PNG file
Drag and drop it into the converter, or click to browse. PNG files up to the size limit are accepted, and nothing is uploaded — processing runs locally in your browser.
- 2
Set BMP options
Pick your quality: the converter exposes the settings that matter for BMP. Higher bitrates preserve more of the PNG's detail at larger file sizes.
- 3
Download the BMP
Conversion runs on your device. When it completes, download the BMP file — repeat for as many files as you need, free and unlimited.
Key Facts About PNG to BMP Conversion
- PNG: created 1996 as a patent-free replacement for GIF, lossless DEFLATE — screenshots and graphics compress extremely well.
- BMP: Microsoft/IBM, Windows 1.0 era (1985), usually none — 24-bit BMP is width×height×3 bytes.
- PNG strength: perfect quality — no generational loss on re-save.
- BMP strength: trivial to read and write — no decoder needed.
- PNG limitation to know: photographs balloon to 5–10× JPEG size.
- BMP limitation to know: huge files.
PNG vs BMP: Format Comparison
What is PNG?
PNG is a lossless image format that supports transparency. It is ideal for graphics, logos, and images that require a transparent background.
- File extension: .png
- Developed by: PNG Development Group
- Best for: Graphics, logos, images with transparency
What is BMP?
BMP is an uncompressed raster image format. It produces large file sizes but maintains exact pixel data without any compression artifacts.
- File extension: .bmp, .dib
- Developed by: Microsoft
- Best for: Windows icons, exact pixel data preservation
Why Convert PNG to BMP?
- BMP is perfect for windows icons, exact pixel data preservation
- Web browsers load BMP images faster
- BMP supports features PNG doesn't (transparency, animation)
- Converting to BMP reduces file size for web use
- BMP is required by specific applications or platforms
Frequently Asked Questions
Will converting PNG to BMP lose quality?
It depends on the formats: PNG is lossless DEFLATE — screenshots and graphics compress extremely well and BMP is usually none — 24-bit BMP is width×height×3 bytes. Any step from a lossless source into BMP keeps everything; any lossy step re-encodes and discards some data.
Are my files uploaded anywhere during PNG → BMP conversion?
No. This converter runs on WebAssembly inside your browser — your PNG file is read from disk, processed by your device's CPU, and the BMP is written back locally. There is no server upload at any point, which also means no size-based throttling or waiting in queue.
Does the converter keep metadata (title, artist, cover art)?
Where the BMP container supports it, standard tags are carried across. a 1920×1080 24-bit BMP is exactly 6,220,800 bytes of pixel data — you can compute a BMP's size on paper, which is why it's still used in teaching and embedded systems
What BMP settings should I choose?
For legacy Windows assets, start with the converter's default preset — it's tuned for the common case. If you need smaller files, step quality down gradually and listen or look at the result before batch-converting everything.
