What changes
Both formats are lossless, so the quality doesn’t change. What changes is the file size.
The file gets smaller: PNG stores the same content in less space.
PNG supports transparency and BMP doesn’t, so there’s nothing transparent to lose: the background is already solid. What you gain is the option to remove the background later, which a BMP doesn’t allow.
When it’s worth it
Choose PNG for: Logos, screenshots, and graphics. Keeps every pixel and supports transparent backgrounds.
Stay with BMP for: Legacy Windows graphics and raw pixel work.

Questions
Does converting BMP to PNG lose quality?
No. Both formats are lossless.
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.
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.
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.
