The important questions, plus the nearby routes users usually need next.
PNG stores exactly the same pixels as BMP but compresses them, typically shrinking files by 50-90% with zero quality loss. Unless a specific program demands BMP, PNG is the better everyday container: smaller, web-ready, and able to hold transparency for future edits.
Not automatically — BMP images carry no alpha channel, so the converted file is fully opaque. The difference is that PNG can store transparency, so after converting you can open the image in an editor and erase the background without another format change.
Typically 50-90% smaller with zero quality loss — PNG stores the same pixels as BMP, just compressed. Images with large uniform areas compress best; noisy photographs compress least.
No. The entire BMP to PNG conversion happens locally in your browser using the Canvas API, so your files never leave your device. There is nothing to upload, no queue to wait in, and nothing for anyone else to store.
