Why convert PNG to BMP?
PNG is lossless (graphics with sharp edges or transparency). BMP is lossless (Windows-centric legacy interchange). Converting PNG to BMP remaps pixels into the target container in your browser. Transparency from PNG will be flattened because BMP has no alpha channel.
What changes in the file
- Both formats are lossless; pixels stay bit-stable aside from color-space handling
- Alpha from PNG is flattened onto an opaque background
- You can resize, adjust quality where relevant, and strip EXIF on export
- Conversion runs on this device — the file is not uploaded
How to convert PNG to BMP
- Drop one or more PNG files onto the converter (or pick them from disk).
- Confirm the output is set to BMP, then adjust quality, size, or metadata if needed.
- Download the converted BMP file — processing never left your browser.
About PNG
PNG is a lossless raster format with optional transparency. Pixels are preserved exactly, so it is the usual choice for screenshots, UI, logos, and any image that needs a clean alpha channel.
About BMP
BMP is an uncompressed Windows bitmap format. It is simple and widely readable on Windows, but files are large compared with modern compressed formats.
Common questions
Is this PNG to BMP converter free?
Yes. Formatly converts PNG to BMP in the browser at no charge and without an account.
Do you upload my PNG files?
No. Decoding and encoding run locally with browser APIs and WebAssembly codecs when needed. Files stay on this device.
Will converting PNG to BMP reduce quality?
BMP is lossless, so the export keeps the decoded pixels. If the source was already lossy (PNG), prior compression artifacts remain.
