How to convert WBMP to PNG

  1. Add your WBMP images

    Drop WBMP files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.

  3. Download

    Save the PNG, or download everything as one ZIP if you converted several files.

WBMP to PNG: what to expect

WBMP holds only black and white and almost no modern app opens it. PNG keeps every pixel exactly and supports transparent backgrounds. WBMP is at home in tiny monochrome pictures for early mobile phones; PNG is the usual choice for screenshots, logos, graphics with text or transparency.

The defaults suit most files. Under Options you can resize the result.

WBMP holds only black and white, so the result has no greys.

WBMP vs PNG

WBMP

Wireless bitmap

WBMP is the one-bit black-and-white image format of WAP, the mobile web of the late 1990s and early 2000s. Each pixel is on or off and the file is only a few hundred bytes. It is of historical interest and appears in old phone software.

PNG

PNG image

PNG stores every pixel exactly, with optional transparency. It was created as a patent-free replacement for GIF and is the standard for screenshots, logos and interface graphics. Photos saved as PNG are several times larger than the same photo as JPG.

Questions

Are my images uploaded anywhere?

No. The WBMP to PNG conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.

Does converting WBMP to PNG reduce quality?

No further quality is lost: PNG stores the decoded pixels exactly. The result is identical in content.

Can I convert several WBMP files at once?

Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.

How do I convert WBMP to PNG on Windows, Mac, iPhone or Android?

The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the WBMP file, press Convert and save the PNG. There is nothing to install.

Is there a file size limit?

Pictures of up to 120 megapixels are accepted (for example 12,000 by 10,000 pixels); a larger one is refused with a message. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
