BMP to PNG Converter

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

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

PNG is lossless and supports transparency. It is ideal for logos, screenshots and graphics with sharp edges, but photo files get large. PNG 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 PNG files one by one or as a ZIP.

Frequently asked questions

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 BMP files are converted to PNG inside your browser and never sent to a server.
