BMP to PNG

Convert BMP images to PNG online in seconds.

BMP is the uncompressed Windows bitmap format: simple and readable everywhere, but files are very large. PNG keeps every pixel exactly and supports transparent backgrounds, which makes it ideal for editing, screenshots, logos and graphics.

PNG is lossless, so the conversion adds no compression artifacts.

You can drop several BMP files at once and get a ZIP of PNG files. Each file can be up to 20 MB; there's no daily limit and no signup, and uploads are deleted from our servers within 1 hour.
