Your sequence

01

Build your sequence

Choose at least two clips. Move them into order and set optional start and end points.

Choose files to get started.

01 / SEQUENCE

Tell it in your order

Use Move earlier and Move later to arrange clips, including on touchscreens and keyboards. Set individual start and end points before merging.

02 / LAYOUT

Different shapes, one canvas

Keep the complete frame with padding, or fill the canvas by cropping the edges. Mixed sizes and frame rates are normalized for a consistent result.

03 / SOUND

Sound that stays in place

Each clip keeps its own first audio track. Silent clips receive silence when mixed with sound. You can also remove audio from the whole sequence.

What can I merge?

Combine 2–8 video clips, with up to 512 MiB of source files in total. Many MP4, MOV, WebM and MKV recordings work, but encrypted, corrupt, HDR and unsupported codecs are rejected. Images, music overlays and transitions are not part of this video joiner.

Start and end accept seconds or HH:MM:SS.mmm. Leave end blank to keep the rest. Each selection must be at least 0.1 seconds. End points are checked against the actual recording when you export. Video duration is limited by frame precision.

Clips are re-encoded to a common canvas and frame rate, then joined with straight cuts. Re-encoding is lossy and output may be larger. Subtitles, extra audio tracks, descriptive tags, attachments and chapters are omitted.

The engine downloads about 31 MiB on first use. Merging needs more memory than a single-file conversion; use shorter clips if your device runs out of resources. Original media is not uploaded. Keep the page open while exporting.
