Drag-to-Reorder
Rearrange your clips by dragging them into any order — the list order is exactly the order they'll play in.
Seamless Concatenation
Clips are joined back-to-back into one continuous file, normalized to a shared resolution and frame rate first.
Real FFmpeg Engine
The same FFmpeg used by desktop editors runs right in your browser via WebAssembly to build the merged file.
Handles Mixed Resolutions
Clips shot at different resolutions are automatically scaled and padded to match, without stretching or cropping.
Fully Private
Merging runs entirely in your browser's memory — your clips are never uploaded to a server.
Completely Free
No account, no watermark, and no limit on how many clips you combine into one video.

Why Our Video Merger Stands Out: Drag, Drop, Combine

Drag, Drop, Done
Add as many clips as you need, drag them into the order you want, and merge — there's no timeline to learn and no editing software to open.
Matched Resolution, Every Time
Before merging, every clip is automatically scaled and padded to the largest resolution in the set, so there's no jarring size jump between segments.
Real FFmpeg Concatenation
Video Merger runs FFmpeg compiled to WebAssembly to normalize and stitch your clips together, the same technique used by professional editing tools.
Private by Design
Every clip stays on your own device throughout the entire merge — nothing is uploaded, and no account is ever required.
