BMP to JPEG 2000 Converter

Convert BMP files to JPEG 2000. Batch, free and without uploading.

This tool converts BMP files to JPEG 2000. BMP is Windows’ uncompressed bitmap format. It stores every pixel as is, so files are very large, but almost every program opens it.

JPEG 2000 is used in archives, digital cinema and medical imaging. JPEG 2000 is lossy, and you choose the quality with the slider. For photos, 80–90% makes the file much smaller with a loss you won’t notice.

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. Set the quality and, if you like, a maximum size.
3. Press "Convert" and download the JPEG 2000 files one by one or as a ZIP.

Frequently asked questions

Will converting to JPEG 2000 reduce quality?

JPEG 2000 is lossy, but at 85–90% quality the difference isn’t visible. Lower quality means a smaller file.

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 JPEG 2000 inside your browser and never sent to a server.
