ToolGPT

Convert AVI to MP4 just by asking

Attach your AVI file, type “Convert this to MP4”, and ToolGPT does the rest: it reads the video's details, picks the settings and converts it in your browser. You can ask for a smaller resolution or a lower bitrate in the same message.

How it works

  1. 1

    Open ToolGPT and press the + button beside the message box, or drop the file into the chat. No account is needed to start.

  2. 2

    Ask for MP4

    Type what you need, such as “Convert this to MP4”. Add a resolution, frame rate or bitrate if you have a target in mind.

  3. 3

    Download the MP4

    The result appears as a card in the chat with a download button. Your AVI stays as it was.

Why convert AVI to MP4?

AVI files from older cameras and Windows software are often large, will not play in browsers or on phones, and are refused by many social sites. ToolGPT always re-encodes an AVI's video as H.264 with a WebAssembly build of FFmpeg, so a long file can take a while on a slower computer.

How ToolGPT converts AVI to MP4

The conversion runs in your browser. ToolGPT uses the browser's own video encoders where they can do the job and a WebAssembly build of FFmpeg where they cannot, so the video is not uploaded to a server to be converted. The assistant sees only the facts it needs to choose settings, such as the file's length, size and dimensions.

Because your own device does the work, a long or high-resolution video takes longer on an older computer or phone. A progress bar shows how far the job has got, and you can keep chatting while it runs.

About AVI

AVI, short for Audio Video Interleave, is an old Microsoft container that Windows programs, digital cameras and camcorders used for years. Most desktop media players still recognize it. Its files tend to be large, though, and browsers, phones and many editing apps cannot play AVI directly.

About MP4

MP4 is the standard MPEG-4 video container, used by phones, cameras, streaming sites and editing apps. It usually holds H.264 or HEVC video with AAC sound. Its strength is that it plays almost everywhere; its weakness is that the video is compressed with loss, so each re-encode costs a little quality.

Frequently asked questions

Is my AVI file uploaded?

No. The conversion runs in your browser. Your messages go to the AI assistant, but the video itself is processed on your device.

Can I change the resolution or the file size?

Yes. Ask in the same message, for example “Convert this to MP4 at 720p”. Without a request, ToolGPT keeps the video's own resolution.

Can I convert several AVI files at once?

Yes. Attach them together and ask for MP4. ToolGPT shows one plan for all of them with a Start button, and each file gets its own result.
