What does converting PNG to BMP mean?
PNG is a lossless raster format that preserves every pixel exactly, including transparency, while BMP is an uncompressed raster format that stores every pixel with no compression at all. BMP is uncompressed and compatible with every Windows application and legacy software.
PNG uses lossless compression, so zero image data is discarded, which makes it the standard choice for logos, icons, screenshots, and graphics with sharp edges or transparency. The tradeoff is larger file sizes for photographic content compared to lossy formats.
BMP files are typically 10-20 times larger than an equivalent JPG or PNG because no compression algorithm is applied. It remains common in Windows-native applications and legacy software.

When to convert PNG to BMP
Preparing PNG files for legacy Windows applications that require raw, uncompressed pixel data
Convert PNG images to BMP when your project specifically calls for legacy Windows applications that require raw, uncompressed pixel data.
Reducing file size
If BMP compresses better than PNG for your content, converting can significantly cut storage and bandwidth needs.
Improving compatibility
Some platforms and software only accept certain formats — converting to BMP ensures your PNG files open everywhere they need to.
Batch migrating a library
Convert a whole folder of PNG images to BMP at once instead of opening each file individually in an editor.

Frequently Asked Questions
Will converting PNG to BMP reduce image quality?
Since BMP is a lossless format, no additional quality is lost when converting your PNG file. If the original PNG was already compressed with quality loss, that loss can't be recovered, but nothing further is discarded.
Does BMP support transparency?
No, BMP does not support transparency. Any transparent areas in your PNG file will be filled with a solid background (typically white) when converted to BMP.
Is it safe to convert PNG files to BMP here?
Yes. The whole PNG to BMP conversion runs locally in your browser using the Canvas API — your PNG files are never uploaded to a server.
Can I convert several PNG files to BMP at once?
Yes, drop multiple PNG files at once and click Convert All — each one is converted to BMP and can be downloaded individually or as a ZIP.
Is there a size limit for PNG uploads?
There's no hard limit set by Pixvert for PNG files, but very large files depend on your device's available memory to convert smoothly.
Can I use the BMP output commercially after converting?
Yes, converting PNG to BMP only changes the file format — it doesn't alter your rights over the image or add a watermark.
