Add a PNG
Upload, drop, or paste the PNG you need as a Windows-style bitmap, keeping the 12-million-decoded-pixel limit in mind.
Free PNG to BMP converter
Export a BMP fromdecoded PNG pixels.
This free online PNG to BMP converter creates a simple 24-bit Windows bitmap in your browser. It reads the PNG as pixels, writes BGR rows from bottom to top, and composites transparent areas against white.

About this converter
Free PNG to BMP conversion, built for a real workflow.
PNG can carry lossless pixels and transparency, whereas this Fileverses BMP output is a 24-bit Windows bitmap. The browser decodes the PNG, then the encoder writes uncompressed BGR pixel rows in bottom-up order with four-byte row padding. BMP output here has no alpha channel: transparent or partly transparent PNG pixels are blended with white. It does not preserve PNG metadata or guarantee a smaller result.
- The output is a 24-bit Windows BMP with BGR pixel order and bottom-up rows, not a PNG file with a changed extension.
- Each BMP row is padded to a four-byte boundary, so its size depends on image dimensions as well as pixel content.
- Transparent and semi-transparent PNG pixels are composited onto white because this encoder writes no BMP alpha channel.
- The converter works from decoded canvas pixels and does not retain original PNG bytes, metadata, layers, or prior edit history.
- Decoded images above 12 million pixels are rejected, and an uncompressed BMP can be substantially larger than the source PNG.
How it works
Upload once.
Export BMP.
Review transparent areas
BMP is selected on this page. If the PNG has alpha, expect transparent pixels to be blended onto white in the result.
Convert and test
Download the BMP and open it in the specific legacy application or Windows workflow that requires this bitmap format.
Made for real pipelines
PNG to BMP.
One workspace.
Convert without uploading your assets. Switch outputs anytime — web, print, icons, and document targets from the same batch.
Convert PNG to BMP24-bit BGR bitmap
Creates a conventional Windows-style BMP with three color bytes per pixel and bottom-up pixel rows.
White alpha compositing
Makes the alpha boundary explicit: transparent PNG pixels are blended onto white before BMP bytes are written.
Legacy-format handoff
Download a bitmap for the exact program or workflow that asks for BMP, then validate it in that destination application.
Good to know
Questions, answered.
Is the PNG to BMP converter free online?+−
Yes. This PNG to BMP converter is free online and does not require an account or sign-up.
What kind of BMP does this tool create?+−
It creates a 24-bit Windows BMP with BGR pixel order, bottom-up rows, and row padding to a four-byte boundary.
What happens to transparent PNG pixels?+−
The BMP encoder has no alpha channel. Transparent and partially transparent PNG pixels are composited against white.
Will the BMP be smaller than my PNG?+−
Usually do not assume that. This BMP is uncompressed, and its size depends on dimensions, row padding, and three color bytes per pixel.
Does the BMP keep PNG metadata or layers?+−
No. The conversion encodes browser-decoded pixels, not the original PNG bytes, metadata, layers, or edit history.
What PNG size can I convert to BMP?+−
The PNG must decode to 12 million pixels or fewer. The tool does not promise an output size or change image dimensions automatically.
