Resize and reframe video locally for vertical, portrait, square, landscape or custom canvases with smart crop, fit, blurred background, focal-point control and verified exports.
Social & presentation presetsVertical, portrait, square, landscape and exact custom canvases.
Four framing enginesSmart crop, fit + color, blurred background, or deliberate stretch.
Focal-point controlKeep the subject left, right, high or low instead of blindly center-cropping.
Choose a video. Nothing is uploaded.
All dimensions are even-pixel normalized. Smart crop preserves aspect ratio; Fit and Blur preserve the whole source picture.
Reframing advisorUse Smart crop when the canvas must be filled edge-to-edge. Move Focus X/Y toward the subject before exporting portrait or vertical versions.

Resize without guessing
Pick a ready-made canvas or enter exact dimensions. The live frame shows whether the result will crop, letterbox, blur-fill or stretch before you spend time rendering.
Smart crop
Smart crop scales until the output canvas is completely filled, then removes overflow. Focus X/Y decides which side receives more of the remaining picture.
Fit and blurred background
Fit keeps every source pixel visible with a solid background. Blur mode fills the canvas with a softened copy of the video and overlays the intact source on top—a polished way to place landscape clips in vertical frames.
Exact creator canvases
Included presets cover 9:16 vertical, 4:5 portrait, square and common landscape HD sizes. You can override both dimensions for ads, presentations, signage or custom publishing systems.
Quality and frame rate
Keep the source frame rate unless a platform or production workflow requires 24, 30 or 60 fps. Higher dimensions and frame rates require more browser memory and longer local encoding.
Privacy and limits
The normal workflow processes media locally, without an account or watermark. Very large 4K files can exceed mobile-browser memory; desktop browsers are recommended for demanding conversions.
