Video merger for clips, GIFs and photos

Browser-based video merger with per-clip editing and 40+ transition effects. Trim, adjust speed and volume for each clip individually, then combine MP4, WebM, MKV, MOV files with fades, wipes, slides. No watermark, no account required.

How to Merge Videos Online

1
Upload your videos and photos

Drag and drop two or more files — videos, GIFs or photos. Supports MP4, WebM, AVI, MKV, MOV, JPG, PNG, HEIC. The upload zone prints the size ceiling itself; on a phone it is lower.

2
Edit each clip

Expand any clip to trim start/end, adjust speed (0.25–4x), volume (0–200%), rotation, and audio fades. Drag clips to reorder.

3
Add transitions and music

Choose transitions between clips — fade, wipe, dissolve, slide, and 30+ more effects. Add background music: you can take it off any clip, and that clip keeps its own sound.

4
Preview and merge

Preview the sequence, pick output format and quality, then click Merge. Your combined video is processed in-browser and downloaded directly.

Frequently Asked Questions

Can I merge videos of different resolutions?

Yes! The tool automatically scales all videos to a common resolution. Choose Auto, 480p, 720p, 1080p, 1440p, or 4K.

Can I trim or speed up individual clips?

Yes. Expand any clip to trim its start/end, change speed from 0.25x to 4x, adjust volume, add audio fades, and rotate.

What is lossless merge mode?

When all clips have the same resolution and format with no edits applied, the tool merges them instantly without re-encoding — preserving original quality.

Can I add music but keep the original sound on one clip?

Yes. Add background music and press ♫ on that clip's card: the music fades out right before the clip starts (during the transition, if there is one), and you hear the clip's own sound. The “Replace clip sound with the music” checkbox removes the sound of the other clips wherever the music plays.
