Frequently Asked Questions
Why won't my DDS file open?
DDS files may not open if your device lacks the right codec or application. Converting to PPM — a more widely supported format — usually resolves this. PPM (Portable Pixmap) is a simple uncompressed image format used in scientific imaging.
Is it safe to convert DDS to PPM online?
Yes. CocoConvert encrypts your file via TLS, processes it on isolated servers in Germany, and permanently deletes it within 24 hours. Your files are never shared or analysed.
Will I lose quality converting DDS to PPM?
Converting DDS to PPM maintains high quality with CocoConvert's optimised encoder settings. CocoConvert uses high-quality encoder defaults to preserve as much fidelity as possible.
How large can my DDS file be?
