Frequently asked questions

Is my file uploaded anywhere?

No — this tool runs entirely in your browser using JavaScript/WebAssembly. Your file is never sent to a server.

Is there a file size limit?

Free accounts can process files up to the limit shown on this page; signing up for Pro raises that limit substantially.
