Switch your video between landscape, vertical, square, and story aspect ratios with smart crop or letterbox padding. Free, no watermark, entirely in your browser.
Drop any MP4, MOV, or WebM file into the tool, or click to browse.
Choose 16:9 (landscape), 9:16 (vertical for Reels/TikTok), 1:1 (square) or 4:5 (Instagram feed), then pick Crop or Pad mode.
The tool re-encodes the file with the new frame, then offers a direct download.
Crop fills the new frame by cutting away content that doesn't fit. Pad keeps the whole frame visible by adding black bars on the sides or top/bottom.
16:9 for YouTube and landscape players, 9:16 for TikTok / Reels / Shorts, 1:1 for square posts, and 4:5 for Instagram feed.
The video is re-encoded with CRF 23, which is visually lossless for most content. Cropping does discard pixels, so heavy crops may look softer.
Yes, but mobile CPUs are slower and RAM is more limited. Shorter clips work best on phones.
