Why teams trust this converter
Zero-Trust Ready
Files never leave the tab. PNG binaries live inside WebAssembly memory and are disposed of immediately after producing a DNG output.
Format-Aware Presets
We tune FFmpeg flags so PNG characteristics (color depth, metadata) persist when writing DNG deliverables.
Ops-Level Observability
Each run exposes duration, file size deltas, and CPU hints so production teams can benchmark PNG → DNG workflows.

Processing happens on-device, so most PNG to DNG jobs finish in seconds. Larger videos scale with your CPU speed but never wait in a remote queue.
When should I pick DNG instead of PNG?
Portable Network Graphics offers lossless format supporting transparency, ideal for logos and digital art. whereas Digital Negative is better suited for open raw photography format that preserves sensor data for non-destructive editing.. Choose DNG when you need photography archives.
