How do I convert BMP to HDR?

Drop your BMP file onto the converter above, make sure HDR is selected, and click Convert. When it's done, download the HDR file — it usually takes a few seconds.

Is it safe to convert BMP to HDR here?

Yes. BMP to HDR conversion happens entirely inside your browser using WebAssembly, so your file is never uploaded to any server.

Is the BMP to HDR converter free?

Yes — free with no watermark. Signed-out visitors can convert 25 files a day, and a free account raises that to 250.

Will converting BMP to HDR reduce quality?

No — HDR preserves the content of your BMP file as faithfully as the format allows.

Can I convert multiple BMP files at once?

Yes. Add up to 5 files at a time without an account, 10 with a free account and up to 500 on paid plans, then download them individually or as a single ZIP.

Can I convert HDR back to BMP?

Yes — use our HDR to BMP converter. Note that converting back and forth between formats can't recover detail lost to lossy compression.
