Choose the Blurred backdrop or Solid bars fill mode. Both keep every pixel of your original frame: the video is scaled to fit the 16:9 canvas and the space on either side is filled with a blurred, zoomed copy of the footage or with plain black/white bars. Nothing is trimmed and the audio is untouched.
Yes — the target orientation is a setting, not a fixed direction. Pick Vertical (9:16) to reformat landscape footage for Reels, Shorts or TikTok, or Square (1:1) for feed posts. The same blur, bars, and crop fill modes apply in every direction.
It is the standard look you see on TV news and YouTube when phone footage airs: your full vertical video sits centred and sharp, while an enlarged, heavily blurred copy of the same footage fills the rest of the widescreen canvas. It reads as intentional rather than as black dead space.
Yes. The audio track is carried over (re-encoded to AAC for compatibility) and the duration, frame rate and timing of the video are unchanged. Only the canvas around the picture changes.
1920×1080 for horizontal, 1080×1920 for vertical, or 1080×1080 for square — with a 720p option for smaller files. Output is MP4 (H.264 + AAC), which plays everywhere.
Use Crop when you want the frame completely filled with no bars or blur — for example a centred talking-head clip where losing the top and bottom (or sides) does not matter. Be aware it trims the longer edges, so action near the edges will be cut off.
No. FFmpeg compiled to WebAssembly does the conversion inside your browser tab. The file never leaves your device — no upload, no account, no watermark.
Up to 500MB. Very long or high-resolution clips take longer since the single-threaded WebAssembly encoder runs on your own CPU.
