What changes
Both formats are lossless, so the quality doesn’t change. What changes is the file size.
The file gets larger: BMP needs more space for the same content.
Watch out for transparency: PNG has an alpha channel and BMP doesn’t, so transparent areas are filled with the background color (white unless you pick another).
When it’s worth it
Choose BMP for: Legacy Windows graphics and raw pixel work. Any program can read it, with no compression to decode.
Stay with PNG for: Logos, screenshots, and graphics.

Questions
Does converting PNG to BMP lose quality?
No. Both formats are lossless.
What is the BMP format?
Microsoft's uncompressed bitmap from 1992: a small header followed by raw pixel rows, usually 24 bits per pixel. Windows still uses it internally, for instance for images copied to the clipboard.
What is the PNG format?
Lossless image format from 1995, standardized as ISO/IEC 15948. It compresses with Deflate and supports an alpha channel and 8 or 16 bits per channel, which is why it’s the default for screenshots, logos and anything that has to stay sharp.
Are the files uploaded?
No. The file is opened in this tab, converted here and saved from here. There’s no account and no watermark.
How many files can be converted at once?
Up to 200 per batch and about 2 GB per file, within the memory this device has available.
