Merge multiple video files into one continuous video using FFmpeg concat, joining them smoothly in alphabetical order, upload a ZIP archive containing all the video files you want to combine
Our free video merger joins several clips into one continuous video, so you can combine videos into one file without editing software or a subscription. You upload a single ZIP archive containing all the clips you want to combine, and the tool stitches them together in alphabetical filename order, then hands you one finished video to download. It runs on FFmpeg, the same professional engine behind countless video apps, using a fast concat that joins your clips cleanly. Whether you need to merge two videos or combine dozens of parts into one movie, you can do it online in your browser, with no watermark, and nothing to install.
Merging videos with File Tools Online takes three quick steps, and you do not need Premiere Pro, iMovie, or any desktop editor. Everything runs online in your browser, and all you upload is one ZIP archive.
Name your video files in the order you want them to play, add them all to a single ZIP archive, and drag that ZIP into the box above.
The tool reads every clip inside the ZIP and merges them in alphabetical filename order into one continuous video using the FFmpeg concat.
Download the single combined file. For the cleanest join, the clips should share the same format and resolution.
The result is one continuous video that plays your clips back to back in the order you named them. That makes it easy to turn a folder of separate recordings into a finished piece you can upload, share, or keep as a single file instead of a scattered pile of parts.
A lot of "combine video" tools add a watermark or make you upload each clip through a clunky one-at-a-time queue. Ours keeps it simple: one ZIP goes in, one merged video comes out, powered by the professional FFmpeg engine.
Clips are joined end to end into a single continuous file that plays straight through, with no gaps between the parts.
Built on FFmpeg concat, the professional standard for joining video, so the merge is fast and the output plays everywhere.
Bundle every clip into one ZIP and upload it once. No fiddly one file at a time process and no ordering menus to click through.
Combine videos free online with no trial, no branding stamped on your footage.
Your ZIP is processed over an encrypted connection and your files are automatically deleted from our servers after a short time.
Runs online on Windows, Mac, Linux, Chromebook, Android, and iPhone. Nothing to download and nothing to install.
Instead of adding clips one by one, you gather everything into a single ZIP archive and upload that one file. The tool opens the ZIP, finds every video inside it, and merges them into one continuous video. This keeps the whole job to a single upload, even when you are combining a lot of clips at once.
The order of the finished video is decided by the filenames, not by the order you added them to the ZIP. The tool sorts the clips alphabetically and joins them in that sequence, so a file named a-intro.mp4 plays before b-middle.mp4, which plays before c-end.mp4. Because the order is driven entirely by the names, you stay in full control: rename your clips and you reorder the final video.
For the smoothest result, the clips inside the ZIP should ideally share the same format and resolution. When every clip is, for example, an MP4 at the same width and height, FFmpeg can concatenate them cleanly into one file. If your clips are mixed, it is worth converting them to a common format and size first, which the tips below cover.
Separate video files pile up fast, and a single continuous version is almost always more useful. Here are the situations where people reach for a video combiner most often.
File Tools Online offers more than 100 free tools to convert, edit, and manage your files. These are the ones people use most alongside the video merger.
Because the tool joins your clips in alphabetical filename order, the names you give your files are what decides the sequence of the finished video. This is the single most important thing to get right before you zip everything up, and it is easy once you know the trick.
The simplest reliable method is to add a number prefix to the front of each filename: 01, 02, 03, and so on. Two digit numbers keep the sort correct once you pass nine clips, so a file named 01-opening.mp4 always plays before 02-scene.mp4, and 10-outro.mp4 lands after 09 instead of jumping ahead. Without the leading zero, plain names can sort in a way you did not expect, for example clip10 can come before clip2.
So the safe recipe is: decide the order you want, rename each clip with a padded number in front (01, 02, 03), add them all to one ZIP, and upload. The tool follows that number order exactly, and you get a merged video that plays in the sequence you planned.
Because this is an online video merger, it works the same on every device. There is no program to install on Windows, no app to download on Mac, and nothing to add to your phone, you use the exact same page whether you are on a laptop, a Chromebook, an Android device, or an iPhone.
That makes it easy to combine videos on Mac, on a work computer where you cannot install software, or on your phone when your clips are already sitting in a folder. The merging runs on our servers with FFmpeg, so even a long combined video is produced without leaning on your own device's power. All you need is a browser, an internet connection, and one ZIP of your clips.
Yes. The clips people merge are often personal recordings, family footage, and unreleased work, so privacy matters. Your ZIP is uploaded over an encrypted HTTPS connection, processed on a secure server, and your files are automatically deleted after processing. We never share, sell, or reuse your videos.
Add all the clips you want to combine into one ZIP archive, name them in the order you want them to play, and upload the ZIP to the tool above. It joins them in alphabetical order into one continuous video using FFmpeg, then gives you the merged file to download.
The File Tools Online video merger is free to use, with no watermark added to your footage. Just zip your clips, upload the archive, and download the combined video.
Bundling every clip into one ZIP keeps the whole job to a single upload, even when you are combining many videos. The tool opens the ZIP, reads each clip inside, and merges them all in one pass.
Clips are joined in alphabetical filename order, not the order you added them to the ZIP. Name your files so they sort the way you want, for example with number prefixes like 01, 02, and 03.
Rename your clips with a padded number at the front (01, 02, 03) before you zip them. Two digit numbers keep the order correct past nine files, so the video plays in exactly the sequence you planned.
Yes. Put both clips in a ZIP, name them so the one you want first sorts first (for example 01 and 02), and upload. The tool joins the two videos into a single file.
For the cleanest concat, your clips should ideally share the same format and resolution, such as MP4 files at the same width and height. If they are mixed, convert them to a common format first with our Video Convert tool.
The concat joins your clips as they are, so it does not re-encode and degrade footage that already shares the same format and settings. The merged video keeps the quality of the clips you put in.
Yes. Add as many clips as you like to a single ZIP and the tool merges them all in one go. A longer combined video simply takes a little more time to process.
Create a ZIP of your clips on your phone, then open this page in your mobile browser and upload it. The merge runs on our servers, so there is no app to install on Android or iPhone.
No. The tool adds no watermark and no branding to your footage. You download a clean combined video that contains only your own clips.
Yes. Your ZIP is transferred over an encrypted connection, processed securely, and your files are automatically deleted after processing. We never share or sell your videos.
Video comes to us in pieces. Cameras split long recordings into numbered chunks, phones capture a moment at a time, and screen recorders save each session separately, which leaves you with a folder of clips instead of one finished video. Merging videos solves that by joining those separate files back into a single continuous piece you can actually watch, upload, and share.
A good video combiner should do that without re-encoding your footage into something worse or forcing you into paid editing software. This free online tool joins your clips with the FFmpeg concat, the professional standard for stitching video together, and keeps the workflow to one simple step: upload a ZIP of your clips, and download one merged video. Because the join follows alphabetical filename order, you control the sequence just by naming your files, and clips that share the same format and resolution combine into a clean, unified result. It is free to use, with no watermark and no software to install, so you can combine videos into one whenever you need to, right in your browser.
