Questions people ask
- Does this work offline?
- Once the page and converter have loaded, yes — no network is needed for the conversion itself.
- Is my Signal file uploaded anywhere?
- No. The conversion runs inside this browser tab with FFmpeg compiled to WebAssembly. The file is read from your device and never sent over the network, so private conversations stay private.
- Is there a size or daily limit?
- No server limit and no daily cap. The practical ceiling is your device memory; desktops handle multi-gigabyte files, phones are happiest with an hour or two at a time.
- Can I convert several files at once?
- Yes. Queue up to 60 files; each shows its own progress and you can download them one by one or as a single ZIP.
