How do I convert HDR to DDS?

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

Is it safe to convert HDR to DDS here?

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

Is the HDR to DDS 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 HDR to DDS reduce quality?

DDS is a lossy format, but our defaults are tuned to be visually indistinguishable for most files. You can raise the quality under Options.

Can I convert multiple HDR 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 DDS back to HDR?

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