PGM to BMP Converter

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

This tool converts PGM files to BMP. Portable graymap.

BMP is Windows’ uncompressed bitmap format. It stores every pixel as is, so files are very large, but almost every program opens it. BMP 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 PGM 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 BMP files one by one or as a ZIP.

How many files can I convert at once?

There is no limit. Select hundreds of files together and download the results as one ZIP.

Are my files uploaded anywhere?

No. Your PGM files are converted to BMP inside your browser and never sent to a server.
