Attach a landscape clip, a square video or a screen recording and say “make this TikTok ready”. The TikTok recipe fits the whole picture into a vertical 1080×1920 frame, fills the empty space with a blurred copy of your video, and writes an MP4 in your browser.
Open ToolGPT and add the clip with the + button or drop it into the chat. MP4, MOV, WEBM, MKV, AVI and FLV files all work.
Ask for TikTok. A card shows a live preview in the 9:16 frame, the background choices and, for a long video, the part that will be kept.
Press Apply, or ask ToolGPT to apply it for you. The new MP4 appears in the chat with a download button.
The result is always a 1080×1920 video in a 9:16 frame, with H.264 video and AAC audio at 128 kbps in an MP4 file. A video that is already vertical, such as a phone recording, fills the frame. A 4K vertical clip is scaled down to 1080×1920, and a MOV or MKV comes back as an MP4.
The frame rate follows your video, up to 60 frames per second. A 30 fps clip stays at 30 fps, because the recipe never adds frames. A clip recorded at 120 fps comes out at 60.
A wide clip becomes a band across the middle of the vertical frame. The space above and below is filled with a blurred, enlarged copy of the same video, so the frame never looks empty. Because nothing is cut off, on-screen text and people at the edges of the picture stay visible.
On the card you can make the blur stronger or darker, or switch to a solid color, such as black or white. The preview updates as you change it.
The TikTok recipe keeps at most 60 seconds. For a longer video the card starts with the first 60 seconds selected and shows a filmstrip, where you can drag the window to the part you want. You can also type a start time, such as “use the minute from 2:30”. A video of 60 seconds or less is kept whole.
The platform name is added to the front of your file name, so beach_day.mov comes back as tiktok_beach_day.mp4. Your original file is not changed.
No. The recipe runs in your browser, using the browser's own video encoder where it can and a WebAssembly build of FFmpeg where it cannot.
No. It prepares the file; you download it and upload it to TikTok yourself.
Yes. The card has a button for each platform, so you can switch the same video to Instagram Reels or YouTube Shorts before you apply.
