How to convert PNG to BMP
Convert your files in three simple steps directly in your browser:
02
Convert to BMP
The browser decodes the source locally, then writes BMP at original pixel dimensions in browser memory.
03
Download BMP
Save individual converted BMP files, or download the entire batch as a single ZIP archive.
Key Advantages
Why Convert PNG to BMP Locally?
Experience fast, secure, and lossless conversion with our privacy-first browser architecture.
Privacy & SecurityZero Uploads
100% Private In-Browser Processing
Your PNG photos are decoded and encoded directly inside your browser tab memory. No files are ever sent to remote cloud servers, keeping your personal photos and sensitive documents completely secure.
Zero network transmission - Complete local security
Fidelity & EngineOptimized BMP
Pixel-Perfect Visual Quality
BMP is written uncompressed, so nothing is lost - but expect a file several times larger than the source. BMP needs no compression library - it is assembled from the decoded pixels by a small built-in writer.
Original dimensions preserved - No watermarks
ArchitectureWASM Pipeline
How the Conversion Pipeline Works
The conversion executes in two discrete steps inside this browser tab: first, the PNG source is decoded into uncompressed raw pixels in memory. Second, those raw pixels are re-encoded into valid BMP format without quality degradation.

- •Dimensions: Exact pixel resolution is retained.
- •Transparency: Transparent pixels composite onto white.
- •Metadata: EXIF & GPS location tags are stripped for complete privacy.

PNG to BMP FAQ
How do I convert PNG to BMP?
Drop your PNG file into the tool above, then download the BMP. Everything runs in your browser - your image is never uploaded to a server.
Is converting PNG to BMP free?
Yes. There is no signup, no watermark and no limit on the number of files.
Will I lose quality converting PNG to BMP?
BMP is written uncompressed, so nothing is lost - but expect a file several times larger than the source.
What is the difference between PNG and BMP?
Write an uncompressed 24-bit BMP for legacy and embedded software. Uncompressed bitmap for legacy and embedded software.
Does converting PNG to BMP need a plugin or an install?
No. BMP needs no compression library - it is assembled from the decoded pixels by a small built-in writer.
Is transparency kept in the BMP?
No. BMP has no alpha channel, so transparent areas are composited onto white before encoding.
Is EXIF and GPS data kept in the BMP?
No. Conversion goes through raw pixels, so EXIF, GPS coordinates, IPTC and XMP are all dropped. That is usually what you want before sharing a photo - but if you need to keep the format and only remove metadata, use the Metadata Remover instead.
