Converter websites make you hunt for the right dropdown. With ToolGPT you attach the file and say what you need — "make this an MP4", "I need the audio as an MP3" — and the assistant picks the settings and runs the conversion in your browser.
Open ToolGPT and press the + button beside the message box, or drop the file into the chat. No account is needed to start.
Name the format, or describe where the file is going and let the assistant choose. You can also ask for a lower resolution or frame rate in the same message.
The converted file appears as a card in the chat with a download button. Your original is never changed.
For video, ToolGPT writes MP4, MOV, WEBM and MKV. You can keep the resolution as it is or ask for a smaller one, and change the frame rate or bitrate if you have a specific target in mind.
For audio, it can export a file's sound as MP3, WAV, FLAC, OGG, Opus, AAC, M4A or AIFF. That is also the way to pull the soundtrack out of a video: attach the video and ask for the audio as an MP3.
Most people do not know whether they need H.264 or VP9, or what bitrate a file should have. They know what they want to do with it: send it to a colleague on Windows, upload it to a website, play it on a TV. Tell ToolGPT that, and it works out the settings from the file's real details — its length, resolution and current bitrate.
It also remembers the conversation. If the first result is not quite right, say "make it smaller" or "keep the original resolution" and it redoes the job with the change, replacing the earlier result instead of piling up copies.
On your computer or phone. ToolGPT uses the browser's built-in video encoders where they are available and a WebAssembly copy of FFmpeg where they are not, so the video file is not uploaded to a server for conversion. The assistant sees the facts it needs — the file's name, length, size and dimensions — to choose settings.
Because the work happens on your device, a long 4K video takes longer on an older laptop than on a new one. A progress bar shows how far along the job is, and you can keep chatting while it runs.
No. You can open ToolGPT, attach a file and convert it without signing in.
No. Conversion runs in your browser. The chat messages go to the AI assistant, but the video file itself is processed on your device.
Yes. Attach them together and ask for the same conversion for all of them; ToolGPT shows you the plan and runs each file as its own job.
Not at the moment. The video formats it can write are MP4, MOV, WEBM and MKV.
