How to convert PBM to PNG

  1. Add your PBM images

    Drop PBM 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.

  2. PNG is already chosen

    Press Convert. Open Options first if you want to change the defaults. The work happens in this tab.

  3. Download

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

Why ToAny

  • Free, without an account

    No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.

PBM to PNG: what to expect

PBM holds only black and white and few everyday apps open it. PNG keeps every pixel exactly and supports transparent backgrounds. PBM is at home in black-and-white line art and scanned text in command-line tools; 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.

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

PBM vs PNG

PBM

PBM image

PBM is the black-and-white member of the Netpbm family: every pixel is a single bit, either on or off, with no greys. It suits fax-like scans and bitmaps and was the format other Unix tools used to hand pictures to each other.

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 PBM 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 PBM 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 PBM 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 PBM 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 PBM 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.
