How Elixuvo works
No software installation, no credit cards, and zero account friction. Run high-performance file utilities directly in your browser.
Choose a tool
Search the catalog or start from a category. Live tools process files on the Elixuvo API; preview tools say so on the page.
Add a file or some text
Live file tools read your selection in the browser first, then send it only when you start processing. Text, developer, and JSON tools stay 100% in the browser.
Download the result
When a live tool finishes, download the output from that session. Files are handled in memory for the request and are not stored permanently.
How Elixuvo handles files
Built from the ground up on zero-knowledge and ephemeral computing principles. Your documents and data remain strictly under your control.
Volatile In-Memory Processing
Live file tools process uploads in volatile RAM for the duration of that single request only. Output is delivered directly and files are never stored permanently.
100% Client-Side Sandboxing
Text counters, QR generators, Base64 codecs, UUID generators, and developer utilities execute entirely in your local browser sandbox without network transfer.
Zero Logging & No Accounts
No registration, no sign-ups, and no tracking cookies. We do not store your documents, read payloads, or train artificial intelligence models on your files.
Encrypted Data in Transit
Every network interaction with Elixuvo uses industry-standard TLS 1.3 encryption, ensuring your uploads and downloads remain safe from interception.
