Convert PNG to BMP
Prepare an image for a desktop workflow that specifically needs a bitmap. This is a compatibility conversion and will often increase file size.

How to convert PNG to BMP online
- Select a supported PNG file from your device and check its detected type and size.
- Review the output details and file limits. This tool uses fixed settings, so no settings dialog is needed.
- Choose Convert and wait for the result. A queued job is waiting for a processing slot; a processing job is being handled.
- Download the result and open it in the application where you will use it. Keep the original and remove the server copy when finished.
What you will download
One still BMP image. The first frame or TIFF page is used; source metadata is removed.
Route-specific checks
Choose this route only when the destination specifically requires a bitmap file. BMP output favors simple desktop compatibility over compact storage, removes PNG-specific transparency behavior, and can be substantially larger. Keep the PNG working copy so later edits do not depend on the expanded bitmap.
Available settings
This tool uses fixed output settings; there are no optional settings to change.
Understand your file formats
- PNG is a lossless format useful for screenshots, diagrams and transparent artwork.
- BMP is a bitmap format used by some older desktop applications.
PNG vs BMP: what changes?
- Use PNG when lossless pixels, screenshots, interface graphics or supported transparency matter more than the smallest possible file.
- Use BMP mainly for legacy bitmap workflows; convert to a compressed format when compatibility allows and file size matters.
Technical format comparison: PNG vs BMP
These properties describe the formats and the behavior implemented by this route. They are a decision aid, not a promise that two applications render every file identically.
| Format or operation | Format category | Compression behavior | Transparency support | Multi-page or animation behavior in ConverterZap | Typical best use |
|---|---|---|---|---|---|
| PNG | Raster image | Lossless DEFLATE compression | Yes; supported alpha is kept except when output is flattened to PDF/JPEG | Still image; the first frame is used | Use PNG when lossless pixels, screenshots, interface graphics or supported transparency matter more than the smallest possible file. |
| BMP | Raster image | Typically uncompressed bitmap | No in ConverterZap BMP output | Still image; first frame/page is used | Use BMP mainly for legacy bitmap workflows; convert to a compressed format when compatibility allows and file size matters. |

About your output
PNG preserves pixel detail but photographs can produce large files. BMP files often occupy more storage than compressed image formats. Up to 24 megapixels. The first frame/page is used. EXIF orientation is applied; metadata is removed. JPEG has a white background. HDR and wide-gamut colors are converted to 8-bit RGB; color appearance may change.
Questions about PNG to BMP
Why is the BMP larger than my PNG?
BMP output is intended for compatibility, not size reduction. Its pixel storage is often larger than PNG compression. Use it when the destination specifically requires BMP.
What format detail changes from PNG to BMP?
PNG uses Lossless DEFLATE compression; BMP uses Typically uncompressed bitmap. The conversion writes a new encoded file, so compare transparency, color and file size in the destination workflow.
Which real-world check matters before I share this BMP file?
Open the downloaded result in the application that will receive it and check the behavior described in the limits: Up to 24 megapixels. The first frame/page is used. EXIF orientation is applied; metadata is removed. JPEG has a white background. HDR and wide-gamut colors are converted to 8-bit RGB; color appearance may change.
