Frequently Asked Questions
Why won't my SPH file open?
SPH files may not open if your device lacks the right codec or application. Converting to NIST — a more widely supported format — usually resolves this. NIST is a widely used file format.
Is it safe to convert SPH to NIST 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 SPH to NIST?
Converting SPH to NIST 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 SPH file be?
Free users can convert files up to 250 MB each. Pro users get a 5 GB limit per file, and Business API users have custom limits.
Can I convert SPH to NIST on my phone?
Absolutely. CocoConvert works in any modern browser — iOS Safari, Android Chrome, and all desktop browsers. No app required.
