BMP to PBM Converter

Convert BMP files to PBM. Batch, free and without uploading.

This tool converts BMP files to PBM. BMP is Windows’ uncompressed bitmap format. It stores every pixel as is, so files are very large, but almost every program opens it.

Portable bitmap. PBM is lossless, so nothing is lost from the image during conversion.

Conversion happens inside your browser; your files are never sent to a server.

How to use

1. Drag and drop your BMP files, paste them from the clipboard, fetch one from a link, or use "Choose files".
2. Optionally set a maximum width and height.
3. Press "Convert" and download the PBM files one by one or as a ZIP.
