Frequently Asked Questions
Why won't my DNG file open?
DNG files may not open if your device lacks the right codec or application. Converting to WEBP — a more widely supported format — usually resolves this. WebP is Google's modern image format offering both lossy and lossless compression at 25-35% smaller sizes than JPG/PNG.
Is it safe to convert DNG to WEBP 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 DNG to WEBP?
Your DNG file may contain HDR (High Dynamic Range) data. WEBP only supports standard dynamic range (SDR). Highlights and shadows will be compressed to fit the 8-bit range — subtle detail in very bright or dark areas may be lost. CocoConvert uses high-quality encoder defaults to preserve as much fidelity as possible.
How large can my DNG 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.
