About this tool

Why convert BMP to PNG?

  • What you gain

    PNG is lossless like BMP but compressed, so you get exactly the same pixels in a much smaller file that also works on the web.

  • Good to know

    There’s nothing to lose: the PNG holds exactly the same image. Only the file size changes.

How it works

  1. Add your BMP images

    Drop them in, choose them from your device or paste from the clipboard. Add as many as you like: images in other formats convert too.

  2. Convert to PNG

    PNG is already picked for you. Press Convert and each image becomes a PNG on your device, pixel for pixel.

  3. Download

    Save images one by one, or all at once as a .zip.

BMP vs PNG at a glance

How the two formats compare, so you know what to expect.

  • BMP

    Your files

    An uncompressed bitmap from early Windows. Simple to read, but enormous.

    Best for Legacy software that insists on it. Otherwise there is always a better choice.

  • PNG

    What you get

    A lossless format that keeps every pixel exactly. Great for screenshots, logos and anything with text or sharp edges.

    Best for Screenshots, logos, diagrams, cut-outs with transparency, and master copies you will edit again.

Questions, answered

Will converting BMP to PNG reduce quality?

No. PNG is lossless, so the converted file keeps every pixel of your BMP exactly.

Will the PNG be smaller than the BMP?

Usually, yes. PNG compresses images more efficiently than BMP, so most files get noticeably smaller. You’ll see the exact size of every file, and how much you saved, as soon as it’s converted.

Can I convert lots of BMP files at once?

Yes. Add as many as you like: they’re converted side by side on your device, and you can download them one by one or all together as a .zip.

Do my images leave my device?

No. The BMP to PNG conversion runs entirely in your browser, so your images are never sent anywhere. There’s no sign-up and no limit on how many you convert.
