Video joiner
Join compatible clips or re-encode to a selected output format.
Com utilitzar Video joiner
The video joiner merges two or more clips, in the order you add them, into one MP4. Every clip is scaled to fit a common output size with padding, converted to a shared frame rate and given 44.1 kHz stereo audio before concatenation. You choose an output width up to 1920, a height up to 1080 and a frame rate from 1 to 60.
- Choose a source file. If the tool accepts multiple files, arrange them in the order you want.
- Adjust the basic settings, then open Advanced mode for export and fine-tuning options. Custom settings stay active when the panel is closed.
- Run video joiner, review the output, then use the available copy or download controls.

Preguntes freqüents
Can I join videos with different resolutions?
Yes. Each clip is scaled to fit inside the output size while keeping its aspect ratio, then padded with bars to fill the frame. Output width and height must both be even numbers, with defaults of 1280 by 720.
Why does joining fail when a clip has no sound?
The joiner combines the video and audio stream of every input, so a clip without an audio track makes the conversion fail. Add a silent audio track to that clip first, then join the files again.
How many videos can I combine at once?
Between 2 and 20 files, up to 50 MB each and 100 MB combined. The finished MP4 must stay under 50 MB, and conversion has a 180-second time limit, so very long joins may need lower output dimensions.
Where is my input processed?
This operation processes its source in your browser. Copy and download are explicit actions; source input is not saved in an account or history.
