Merge multiple video clips into one seamless video. Drag-and-drop reordering, preview before export, timeline visualization. Combine videos in any format with automatic re-encoding.
Joining several video clips into a single file is straightforward with the Video Merger. Drag and drop your clips, arrange them in the order you want, and the tool concatenates them into one continuous video. You can mix different formats and resolutions, the merger re-encodes as needed to produce a consistent output. Transitions between clips are seamless, and you can preview the merged result before downloading.

Trim and cut videos precisely with frame-by-frame scrubbing. Set start/end points visually, preview clips in real-time, and export trimmed videos instantly. No upload required - runs 100% in browser.
Convert videos between MP4, WebM, OGG, MOV, AVI, and MKV formats. Device presets for YouTube, Instagram, TikTok, iPhone, Android. Quality options from fast to high quality encoding.
Change video playback speed from 0.25x to 4x. Create slow motion effects, time-lapse videos, or speed ramps. Audio pitch preserved automatically with intelligent adjustment.
Three clips from a shoot need to become one continuous video in order.
Input
a.mp4 + b.mp4 + c.mp4 · same resolution
Output
merged.mp4, joined in sequence, consistent timeline
Clips are concatenated with a unified resolution and frame rate so the join does not stutter or change size mid-playback. Matching parameters first is exactly what prevents the glitches a naive splice causes.

Combine clips from different cameras or phones into one continuous video of a wedding, party, or trip.
Join separately recorded sections of a tutorial into a single seamless video for upload.
Merge a collection of short clips into a longer compilation, such as a monthly vlog or best-of reel.
Combine sequential dashcam or security camera clips that were split into smaller files by the recording device.
Merging videos that share the same codec, resolution, and frame rate can be done by simply concatenating the compressed streams, a fast operation that avoids re-encoding. When clips differ in any of these properties, the tool normalizes them to a common format during the merge. It selects the highest resolution and frame rate among the inputs as the target, scales other clips to match, and re-encodes everything into a single consistent stream. Audio tracks are similarly normalized to a common sample rate and channel layout.
Yes. The tool automatically scales clips to match the highest resolution among your inputs.
There's no hard limit, but merging many large files requires sufficient device memory. If you encounter issues, try merging in smaller batches.
Yes. Audio tracks are resampled and synchronized during the merge so everything stays aligned.
Video is decoded and re-encoded on your own device. Large files never leave your machine.
