Same pixels, smaller file
PNG compresses without losing anything, so every pixel of the BMP is kept exactly. The PNG is usually much smaller than the BMP, often by more than half for screenshots and drawings.
When PNG is the better choice than JPG
Use PNG for screenshots, diagrams, logos, text and anything with sharp edges or flat colours. JPG blurs those edges. For a photo, JPG gives a smaller file, but PNG is safe if you plan to edit it more.
Transparency
If the BMP has an alpha channel, the PNG keeps it. Many old BMP files have none, so the picture will have a solid background.
Check the result
Open the PNG next to the BMP and zoom in on text. They should look the same. If colours are off, the BMP may use an uncommon variant; saving it again from Paint usually fixes this.

- Several pictures at once: each gets its own download.
- Your pictures are processed on your device and never sent to a server.
