Seamly: Video Merger & Joiner

Seamly is a video merger and joiner that combines your clips into one video on your phone. Pick the videos, drag them into order and tap Join. Mix portrait and landscape clips, add a fade between them, and keep each clip's sound in sync. No watermark, no sign-up.

JOIN VIDEOS IN ANY ORDER
• Pick as many clips as you like from your gallery
• Drag to change the order
• Add more clips, use one twice, or remove one
• See the total length before you join

CLIPS OF ANY SHAPE
Mix portrait and landscape videos in one video. Choose the shape you want: like the first clip, 16:9 for YouTube, 9:16 for Reels and Shorts, 1:1 or 4:5. Clips of another shape get black bars, a blurred background, or zoom to fill.

FADE BETWEEN CLIPS
Go straight from one clip to the next, or add a soft fade through black or a quick white flash between them. The sound fades with the picture.

SOUND KEPT IN SYNC
Each clip keeps its own sound, lined up with the picture. Clips without sound stay silent, and you can mute any clip.

ORIGINAL QUALITY WHEN IT CAN
When your clips were filmed the same way, Seamly joins them in seconds without re-encoding, so nothing is lost. Other clips are joined in up to 1080p.

NO WATERMARK
Your merged video is yours. Seamly never stamps its name on it.

PRIVATE AND OFFLINE
Everything happens on your phone. Your videos are never uploaded, and Seamly works without an internet connection.

SAVE AND SHARE
Save the joined video to your gallery (Movies/Seamly) or share it straight to WhatsApp, Instagram, YouTube or any app.

FREE AND PRO
Seamly is a free video joiner with no sign-up. The free version shows a short ad after a video is done.
Seamly Pro removes ads and adds:
• Trim each clip before joining
• Blurred background for clips of another shape
Pro is a one-time purchase or a yearly plan. You can also try a Pro feature for one video by watching a short ad.

Use Seamly to combine videos from a trip, merge short clips into one story, put videos together for a reel, or join parts of a long recording.

Works with MP4, MOV and other common video formats. Joined videos are saved as MP4.
