Zoom into any part of a video, either as a fixed crop zoom for the whole clip or as animated keyframes that punch in, push in slowly or pan Ken Burns style. Smooth easing between keyframes, and the export keeps the original resolution and sound.

How to use the Zoom Video
Choose a video (or press Try a sample clip). A punch-in zoom preset is applied so you can see the effect right away.
Pick Static zoom or Animated zoom. Static zooms the whole clip into one area; animated moves between keyframes.
Set the zoom area by dragging the yellow box in the small editor, scrolling to zoom, or using the Zoom and center sliders.
Add or edit keyframes: move the playhead, press Add keyframe, then set its zoom, time and easing. Presets fill them in for you.
Press Create zoomed video, check the result, then press Download MP4.
How the zoom is calculated
A zoom of Z% keeps a window that is 100 ÷ Z of the original width and height, centered on the point you choose, and scales it back up to the full frame. The window is never allowed to leave the picture, so the edges are always filled with real video. Between keyframes the window's center moves along the chosen easing curve, and the zoom changes on a logarithmic scale (100% → 200% → 400% are equal steps), which is how the eye perceives zoom speed.

Tips for clean zooms
Shoot wider than you need. Recording in 4K and exporting at 1080p lets you zoom up to 200% without any loss of sharpness.
Keep zoom moves short. Punch-ins of a quarter to half a second feel snappy; slow pushes should last the whole shot so the motion is barely noticed.
Don't stack moves. Hold each zoom for at least a second before the next one, or viewers lose track of the subject.
Use Max 1080p when the source is 4K and the target is social media: the file is smaller and encodes much faster.
Frequently asked questions
How do I zoom in on part of a video?
Load the video, choose Static zoom, then drag the yellow box over the area you want and raise the Zoom slider. Everything outside the box is cut away and the area inside is scaled up to fill the full frame, so the output keeps the original size and aspect ratio.
What is a punch-in zoom?
A punch-in is a quick zoom toward a subject, usually from 100% to about 120-200%, used in vlogs and talking-head videos to add emphasis or hide a cut. The Punch-in and back preset zooms in smoothly near the start and returns to the full frame near the end; the Jump cut preset switches instantly.
What is the Ken Burns effect?
It is a slow pan and zoom across a picture so a still scene feels alive, named after the documentary filmmaker who used it on photographs. The Ken Burns preset keeps a gentle 135% zoom and glides the view from one side of the frame to the other over the whole clip.
Does zooming reduce video quality?
Zooming reuses fewer source pixels. At 200% zoom a 1920×1080 video is rebuilt from a 960×540 area, so fine detail becomes softer even though the file is still 1920×1080. The tool shows how many source pixels the strongest zoom uses; 4K footage can be zoomed 200% into 1080p with no loss.
What do the easing options mean?
Easing controls the speed of the move between two keyframes. Smooth starts and ends gently, Linear moves at a constant rate, Ease in speeds up, Ease out slows down into the keyframe, and Instant cut jumps to the new zoom exactly at the keyframe time. Zoom changes are interpolated on a logarithmic scale so they feel even.
What file do I get?
An MP4 file at the original frame rate. Most browsers encode H.264 with AAC sound; some (for example Firefox or Linux Chromium builds) use VP9 or Opus inside MP4, which plays in browsers, VLC and on YouTube. If your browser cannot encode quickly, it records the video in real time instead.
Is my video uploaded anywhere?
No. The video is decoded, zoomed and encoded on your own device, so it never leaves your computer and there is no file size limit beyond your device's memory.
