UNDERSTAND YOUR FILES

PBM vs. PNG: what changes?

Input · PBM

PBM is the Netpbm black-and-white bitmap format.

Output · PNG

A losslessly encoded still-image format, useful for graphics, screenshots, text, and transparent backgrounds.

PNG is a lossless export of the decoded pixels and can retain transparent image regions. Choosing an output format changes how another app reads the file; it does not restore detail missing from your source.

Which settings should you choose?

Start with Original dimensions to retain the decoded pixel size. Select a maximum edge only when you need a smaller output image.

Your files and privacy

Your selected file is converted on your device. You can download the new file while keeping the original unchanged.

Some formats work differently across browsers and devices. Check the converted result before using it for important work. Advertising and other optional website services may have separate privacy practices.

Format compatibility and limitations

PBM P1/P4 black-and-white inputs are supported. PNG is lossless for the decoded pixels, but is not guaranteed to be smaller or recover source detail.

Actual output behavior depends on the input file, your browser, device resources and the converter engine. Check important files before sharing or replacing them.
