How it works
- Upload a video
Tap Upload video and pick the video.
- Pick the shape
The editor opens on Crop with 9:16 and Fit, no crop picked. Tap 4:5, 1:1 Square or 16:9 for another shape, and Blurred, Black or White for the background.
- Save
Tap Resize now. The resized video gets its own link and a Download button.
Nothing is cut off
Fit, no crop keeps the whole picture in the middle and fills the space around it with a blurred copy of the same video, or with black or white. Tap Crop instead to fill the frame and cut the edges.
The size the apps use
A wide video becomes 1080 × 1920 for TikTok, Reels and Shorts, 1080 × 1350 for an Instagram post (4:5) or 1080 × 1080 for a square. A small video is not enlarged. Under Size you can make it 720p or 480p.
Same sound, same length
The sound and the length stay as they are. The video is saved once as an H.264 MP4 at good quality, up to 15 minutes long. Need a smaller file instead? Size makes it fit in 16 MB for WhatsApp or 25 MB for email.
Resize video: questions
How do I resize a video for TikTok or Reels?
Upload it — the editor opens on Crop with 9:16 and Fit, no crop picked. Tap Resize now.
Can I resize a video for Instagram without cropping?
Yes. Fit, no crop keeps the whole video and adds a blurred, black or white background. 4:5 is the shape of an Instagram post, 9:16 of Reels and Stories.
How do I change the aspect ratio of a video?
Tap 9:16, 4:5, 1:1 Square or 16:9 under Crop. Fit, no crop keeps the whole video; Crop fills the frame and cuts the edges.
What size will the video be?
1080 × 1920 for 9:16, 1080 × 1350 for 4:5, 1080 × 1080 for a square and 1920 × 1080 for 16:9 — or smaller, if the video itself is smaller.
Can I make a vertical video horizontal?
Yes — tap 16:9. The vertical video stays whole in the middle, with the background on both sides.
Is it free?
Yes. No sign-up and no watermark.
