Free reordering
Rearrange or remove clips right in the list — they join in exactly the order you set.
Drop in your clips, arrange the order and join them into one file — matching clips stream-copy in seconds, mixed clips get unified in compatible mode, with key data processed locally and no watermark.

Privacy-sensitive steps run in your browser, and data is destroyed when you close the page. Work on private footage, business assets and course recordings with confidence.
Rearrange or remove clips right in the list — they join in exactly the order you set.
When clips share codec and resolution, streams are copied directly — no re-encoding, lossless, done in seconds.
Mixed-spec clips are re-encoded to a unified 720p/30fps before joining — footage from any source can merge.

Merge and download
Drop your clips into the Merge Videos tool in WUJIEE Video Tools, arrange the order, and join in one click. When clips share codec and resolution — say, segments shot on the same phone with the same settings — pick fast mode to stream-copy them: seconds, lossless. When specs differ, use compatible mode to re-encode everything before joining. It all runs in your browser, key data processed locally, no sign-up, no watermark.
Hard-joining clips with different resolutions, frame rates or codecs can indeed cause stutter or sync drift — a natural limit of remux-style joining. Compatible mode re-encodes every clip to a unified 720p/30fps first, fixing mismatched specs at the root; matching clips take the fast stream-copy path instead, which is quick and lossless.
No, we don't keep them: merging runs with ffmpeg.wasm in your browser, key data is processed locally, your data is destroyed when you close the page, and your video content is never used for anything else.
There's no server-side size limit — the number of clips and total length are bounded mainly by your device's memory. For very large footage, shrink each clip with the Compress Video tool first, or use compatible mode to unify everything to 720p before merging for a higher success rate.
