Supported files and limitations
Files stay in memory until you leave or reset. Downloads remain on your device. No secure memory erasure is promised.
Processing stops after 60 seconds. Files and results are held in memory; even within these limits, a low-memory device may fail. Cancel and retry with fewer or smaller files.
Privacy
Files, names, and extracted contents stay in browser memory. A local worker packages or expands bytes. Reset ends processing and releases file references; it does not securely erase device memory. File contents are not uploaded and there is no server fallback. Website and account traffic is separate from file processing. Downloads remain wherever you save them.
