Combine video clips into one video, free and private, in your browser

How to combine video clips into one video

Clip Connect is a free web tool that joins short video clips into a single MP4, directly in your browser. There’s no app to install, no account, and no watermark. Your clips are never uploaded, so they stay private.

1. 1Add clipsSelect your video files, or drag them in. MP4, MOV, WebM, and other common formats work, and photos can join too (each one shows for 2.5 seconds).
2. 2Set the orderSort by date or name, or drag clips into the exact sequence you want. On phones, tap a clip and use its arrow buttons.
3. 3StitchMatching clips join with zero quality loss. Mixed formats are rebuilt into one consistent video.
4. 4DownloadOne MP4 file that plays anywhere, ready to share or post.

Make compilation videos from social media or AI-generated clips

Compilations, montages, highlight reels, a sequence of AI-generated scenes: anything that starts as a folder of short videos can be combined into one. Clips saved from social media apps or exported from AI video generators usually differ in resolution and frame rate; Clip Connect detects that and rebuilds them into one consistent video, so vertical stays vertical and nothing is stretched. If a batch mixes vertical and horizontal clips, you pick which way the combined video should face.

A batch can be up to 25 clips. When your clips all match, they join losslessly, which is light on browser memory, so a matching batch can total 1500 MB in a desktop browser (600 MB on phones). Mixed clips need conversion, which takes much more memory, so those batches are capped at 500 MB in a desktop browser, 200 MB on phones, and 100 MB in browsers that can only convert slowly. Conversion is also held to a few minutes of video per batch, so joins stay quick. You can stitch as many batches as you like.

How long does it take to combine videos?

Clips that already match join in seconds at any size: their video is copied into the new file, never converted. When formats are mixed, Clip Connect converts only the clips that don't match the rest, and in most browsers that conversion runs on your device's video hardware, so it's quick even for large files.

Conversion times are for each minute of video that needs converting, and vary with your device. A few browsers can't use fast conversion; Clip Connect warns you before starting a slow one, and always shows a time estimate and a live timer.

Combine videos without losing quality

When your clips already match, combining them costs nothing in quality. If they share the same resolution, frame rate, and format (like a batch of clips from the same camera), Clip Connect joins them losslessly: the video data is copied into the new file untouched, so the result is bit-for-bit the quality of your originals.

When clips don’t match, no tool can join them without re-encoding. Clip Connect asks first, then converts as little as possible: clips that already match each other pass through untouched, and only the odd ones out are converted to fit them, at quality settings comparable to a video editor’s export. In modern browsers the conversion runs on your device’s video hardware, so it takes about as long as the footage itself, often less. One careful conversion, no repeated generation loss.

Common questions

Is Clip Connect free?

Yes. Clip Connect is free, with no account, no watermark, and no export limits. It runs entirely in your browser, so there are no server costs to pass on.

Are my videos uploaded?

No. All processing happens on your device, in your browser. Your clips are never uploaded, so no one can see them, including the people who run Clip Connect.

Does Clip Connect collect any data about me?

Almost none. We count anonymous events, like “a stitch succeeded”, to see whether the tool is useful. There are no cookies, no ads, and no personal data, and there is no way to tell who did what. Your videos still never leave your device, and nothing about them is sent: no filenames, no content, nothing.

Can I send feedback?

Yes, in two optional ways. The Send feedback box is anonymous: your note goes only to the developer, and it contains only what you type, with no video, no filenames, and nothing about your clips. Because nothing identifies you, there’s no way to reply to it. If you’d rather have a conversation, the footer also has a message link that reaches the developer directly and can be answered. That route is not anonymous, since the developer sees who is writing.

What video formats can I combine?

MP4, MOV, WebM, and other common video formats, plus JPEG, PNG, and WebP photos. The combined output is a standard MP4 that plays anywhere.

Can I add photos to my video?

Yes. Add photos alongside your clips (JPEG, PNG, or WebP) and each one appears for 2.5 seconds in the finished video, sized to match your clips. Photos always need a quick conversion into video; your video clips still join losslessly when they match each other.

Does combining videos reduce quality?

Not when your clips match. Clips with the same resolution, frame rate, and format are joined losslessly, so the result is bit-for-bit the quality of your originals. In a mixed batch, the clips that match each other still pass through untouched; only the odd ones out are converted once, at quality settings comparable to a video editor’s export.

How long does combining videos take?

Clips that already match join in seconds at any size, because their video is copied rather than converted. Mixed clips are converted first: in most browsers that takes seconds for each minute of HD video, and under a minute for each minute of 4K or high-resolution screen recordings. A few browsers can only convert slowly; Clip Connect warns you before starting a slow conversion, and always shows a time estimate and a live timer.

Can I combine clips saved from social media apps?

Yes. Save the clips to your device first, then add them to Clip Connect. Vertical video stays vertical, and clips with different resolutions or frame rates are rebuilt into one consistent video automatically.

Can I combine AI-generated video clips?

Yes. Clips exported from AI video generators are usually only a few seconds long, and their size and frame rate can vary from one generation to the next. Clip Connect joins them into one longer video: losslessly when the clips match, or rebuilt into one consistent MP4 when they don’t.

How many clips can I combine at once?

Up to 25 clips per batch. Matching clips join losslessly, which is light on browser memory, so those batches can total 1500 MB in a desktop browser (600 MB on phones, where browser memory is tighter). Mixed clips need conversion, which is heavier, so those batches are capped at 500 MB in a desktop browser, 200 MB on phones, and 100 MB in browsers that can only convert slowly, with a few minutes of converted video per batch so joins stay quick. You can run as many batches as you like.

Private by design. Everything happens on your device. Your clips aren’t uploaded, so we can’t see them.
