Convert any video to 9:16, 1:1, or 16:9
Every platform wants a different shape. TikTok, Reels, and Shorts are vertical 9:16, Instagram feed posts look best at 1:1 square, and YouTube is 16:9 landscape. This free converter reframes a clip you already have into the ratio you need. You do not need to re-edit from scratch or pay for desktop software.
Pick Fit (bars) to keep all of your footage and add clean black bars, or Fill (crop) to fill the whole frame edge to edge and trim the overflow. The result is a standard MP4 (H.264) that uploads anywhere.
How it works
- Drop in an MP4, MOV, or WebM file.
- Choose your target ratio and whether to pad or crop.
- Click convert. The video is re-encoded right here in your browser.
- Preview and download the new file.
Is it private?
Yes. The conversion runs entirely on your device using ffmpeg compiled to WebAssembly. Your video is never uploaded to a server, which also means there are no file-size upload limits beyond what your own machine can handle.
Tips for the cleanest reframe
- Use Fill (crop) when your subject is centered and you want a full-bleed look.
- Use Fit (bars) when important details live near the edges of the frame.
- For repurposing one clip into many caption variations, open the hook editor after converting.
