Good to know

  • PNG is lossless, so nothing is lost — files are often 50–90% smaller.
  • PNG works everywhere: browsers, Office, phones and email.

Your privacy

Your file is opened and processed by your own browser — it is never uploaded. That also means big files use your device’s memory, so very large files can be slow on older phones.

Frequently asked questions

Is BMP to PNG Converter free?

Yes. BMP to PNG Converter is completely free, with no sign-up, no watermark and no daily limit.

Are my images uploaded anywhere?

No. Your browser reads and converts the files on your own device, so they never reach our server.

Which image format should I choose?

JPG for photos you share or email, PNG for screenshots, logos and anything that needs a transparent background, and WebP for the smallest files on websites.

Does it work on my phone?

Yes. It works in Chrome, Safari and other modern browsers on Android and iPhone — pick files from your gallery or Files app. Large videos and long PDFs are faster on a computer.
