Free BMP to PNG Converter

PNG keeps every pixel of a BMP but compresses it, so files get much smaller with no change to the picture.

  3. Step 3

    Convert

    Each file is turned into PNG in your browser, with progress for the whole batch.

    Save files one by one or all of them in a ZIP.

Questions

Is it free?

Yes. Converting and downloading are free, with no watermark. You don't need an account for small batches.

Are my files uploaded?

No. The conversion runs in your browser on your own device, so your files never leave it and we never see them. Closing the tab clears everything.

Will I lose quality?

No. PNG is lossless, so the converted file keeps every pixel of the picture your browser decoded. Files are often bigger than the original, especially for photos.

How many files can I convert at once?

Up to 25 files per batch without an account, 50 with a free account and 500 on Pro. Each file can be up to 100 MB. Very large images may be scaled down to fit your browser's memory, and the tool tells you when that happens.

What happens to photo details like GPS location?

By default the converted file has no metadata: camera details, date and GPS location are removed. For JPG to JPG you can choose to keep the camera details, with or without the location.
