Attach your FLV 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.
Open ToolGPT and press the + button beside the message box, or drop the file into the chat. No account is needed to start.
Type what you need, such as “Convert this to MP4”. Add a resolution, frame rate or bitrate if you have a target in mind.
The result appears as a card in the chat with a download button. Your FLV stays as it was.
FLV was made for Flash Player, which browsers no longer run, so old downloads and stream recordings in FLV need converting before most devices will play them. Converting cannot add detail that a low-resolution FLV never had, so expect the MP4 to look the same, not sharper.
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.
FLV, or Flash Video, is the container Adobe Flash Player used to stream video on websites. It usually carries H.264 or an older Flash codec, with MP3 or AAC sound. Since Flash was retired, browsers and most devices no longer play FLV, so old files usually need converting before anyone can watch them.
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.
No. The conversion runs in your browser. Your messages go to the AI assistant, but the video itself is processed on your device.
Yes. Ask in the same message, for example “Convert this to MP4 at 720p”. Without a request, ToolGPT keeps the video's own resolution.
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.
