Join, combine & stitch multiple video clips into one seamless file — directly in your browser. Drag to reorder, add transitions, and export in seconds. No app, no server, no signup.
A video merger tool, often called a video joiner or video combiner, lets you seamlessly stitch multiple video clips into a single, continuous file — entirely within your browser. Whether you want to combine MP4 files online, join travel footage, assemble a highlight reel, or compile multiple recordings into one polished presentation, a video merger eliminates the complexity of professional editing software.
Our free online video merger processes every clip locally using the browser's Canvas API and MediaRecorder — meaning your files never travel to any server, keeping your content 100% private. Simply drag and drop your clips, arrange their order, choose a transition style between scenes, then hit Merge Videos for instant results.
Best practices when merging videos: Keep clips in the same resolution and frame rate for the cleanest output. Use the Fade transition for a professional, cinematic look between scenes. Export in WebM for the smallest file size, or MP4 when sharing across devices and platforms. Always preview before downloading to confirm the sequence is exactly right.
Advanced video merging capabilities that rival desktop software — all powered by your browser.
Arrange your video clips in any order by simply dragging them. Intuitive handles make it easy to get the sequence exactly right before merging.
Your videos never leave your device. All merging is done locally in your browser — zero server uploads, zero data stored, zero privacy risk.
Choose from Cut, Fade, Dissolve, or Wipe transitions between clips. Apply globally or set individual transitions for each clip pair.
Preview your merged video before downloading. See exactly how the final output looks including transitions and clip order.
Export your merged video as WebM for the smallest file size, or MP4 for the broadest device compatibility. Choose your quality preset too.
Output in the original resolution or downscale to 1080p, 720p, or 480p. Perfect for targeting specific platforms or file size limits.
Each clip shows a live thumbnail extracted from the video so you can instantly identify and manage clips in your queue.
Unlike many free tools, our video joiner adds absolutely zero watermarks to your exported file. Your video stays clean and professional.
Fully responsive and optimised for desktop, tablet, and mobile. Merge videos on any device with a modern browser — no app install needed.
No experience needed. Our video combiner guides you through every step in seconds.
Click the upload zone or drag and drop your video files. Add as many clips as you need — MP4, WebM, MOV, AVI all supported.
Drag clips up or down to set the exact playback sequence. Use the thumbnail previews to identify each clip at a glance.
Pick a default transition (Cut, Fade, Dissolve, Wipe) or customise between individual clip pairs for a polished final edit.
Hit the Merge button, preview the result, then download your combined video instantly. No watermark, no signup needed.
Upload 2 or more video files, drag to reorder them in the clip list, choose your transition style and export settings, then click "Merge Videos". Your browser handles all the processing — no server upload, no signup, no cost.
Our video merger supports MP4, WebM, MOV, AVI, MKV, and OGV — all major browser-compatible formats. For best results, use clips of the same format and resolution when merging.
Absolutely. All video processing happens entirely within your browser using the Canvas API and MediaRecorder. Your files are never uploaded to any server, stored, or shared — your content remains 100% on your device.
There's no hard limit imposed by the tool. The practical limit depends on your device's available RAM. Most modern computers handle multiple clips totalling 2 GB+ without issue. We recommend merging in batches if you have very large files.
Yes! Choose from Cut (instant switch), Fade (black fade), Dissolve (cross-fade), or Wipe (directional sweep) transitions. You can set a global transition for all clips or customise each clip pair individually.
Never. Unlike many free online video joiners, our tool adds absolutely no watermarks, logos, or branding to your exported video. Your merged file is completely clean.
