Questions about converting DDS to OpenEXR
Is converting DDS to OpenEXR free?
Yes, completely free and without sign-up. There is a per-file size cap for server stability, but no daily quota.
How long does DDS to OpenEXR conversion take?
Typically under a second per image. Large photos, RAW files and multi-page documents take longer because they must be fully decoded first.
Which engine handles DDS to OpenEXR?
This pair is processed by IMAGEMAGICK. If you explicitly pick the other engine and it cannot handle the pair, the converter automatically falls back to the one that can.
Does the OpenEXR output keep transparency?
Transparency support in OpenEXR: Yes. When it is not available, transparent areas are composited onto the background colour you choose, white by default.
Does converting DDS to OpenEXR keep animation?
OpenEXR animation support: Yes. When frames cannot be preserved, only the first frame is written.
Are my DDS files deleted?
Yes. Both the upload and the converted output are deleted automatically after 60 minutes, and you can rely on the fact that access requires an unguessable random token.
About this conversion
DDS and OpenEXR are both well-established image formats, but they were designed for different jobs. Knowing which one wins in which situation saves you both storage and headaches.
On this server the pair is handled by IMAGICK, which decodes the source fully before writing the target. That matters for two reasons: colour profiles are applied consistently, and metadata such as EXIF orientation is baked into the pixels so the result is upright everywhere.
If you need to go back the other way, the reverse conversion is available on its own page — and if you are unsure which format suits your use case, the format guides explain the trade-offs in plain language.
