What Is this tool?
Our free video merger tool lets you easily combine multiple clips into one seamless video. Supports MP4, MOV, MKV, AVI, and more. Join videos online, add audio, and create polished videos in just seconds—fast, secure, and no software needed!
Whether you upload from a laptop, tablet, or phone, the this tool handles MP4, MOV, AVI, MKV, WMV, FLV, WebM, and 3GP without forcing you to install desktop software. Drag and drop a file, adjust settings in the panel, preview the result, and download when you are satisfied.
Also known as a online video editor, free video tool, browser video editor, this page is built for quick edits—no account, no watermark on exports, and no usage cap for normal personal or business work.
Most processing runs locally in your browser when the format allows, which keeps drafts and client assets off third-party servers.

Common Use Cases
Teams reach for the this tool when they need one combined video from multiple clips without opening a heavy desktop suite. Typical jobs include social media clips, YouTube intros, webinar recordings, screen captures, and client review cuts.
Because the tool is web-based, remote collaborators can use the same page from any location—helpful for agencies, teachers, and small business owners who edit files on different devices.
Tips for Best Results
Sort files in playback order before merging. Matching resolution and frame rate across clips reduces sync issues in the final export.
When a portal rejects your upload, compare its file-size and dimension limits with your output, adjust settings, and run the this tool again.
Bookmark this page for repeat tasks—settings stay visible between uploads, which speeds up batch work.
Freelancers and in-house teams bookmark the Online Video Merger because it removes the install-and-export cycle from traditional editors.
When a client sends the wrong aspect ratio or file size, rerun the Online Video Merger with updated presets instead of rebuilding the project in desktop software.
For one combined video from multiple clips, compare the preview carefully before downloading so you catch accidental crops, silence gaps, or over-compression early.
The Online Video Merger pairs well with other EditTools pages—compress after resize, or merge after trim—to finish multi-step jobs without leaving the site.
Online Video Merger FAQ
What does Online Video Merger do?
Join supported video clips into one file. Arrange the clips, review the available options, and download the processed video.
Which files work with Online Video Merger?
This category commonly supports MP4, MOV, AVI, MKV, WMV, FLV, WebM, and 3GP. Use the accepted file types shown in the uploader, because support varies by browser and by the engine behind each tool.
Can I change the order of the files before merging?
Reorder the selected files in the list before you run the merge. The output follows the order shown on the page, not the order in which you picked them.
Will my original file be changed?
No. The work is done on a copy in this tab by a WebAssembly build of ffmpeg, and the result arrives as a separate download, so your original is still there if you need it.
How is my file processed?
It is not uploaded. The processing is done locally by a WebAssembly build of ffmpeg, so the practical ceiling is your device's memory and the limit shown beside the uploader - no queue, no account, no copy on a server.
Is the Online Video Merger free?
Yes. The Online Video Merger is free with no trial limit, subscription, or watermark on downloads. You can use it for personal and commercial projects without creating an account.
