Resize Video Preset Mode - EditKits

Custom Mode: Full Control Over Width, Height, and Strategy

Resize Video Custom Mode - EditKits
Need pixel-perfect control? Switch to Custom Mode. Enter any resolution manually and define how your video adapts using Fit or Fill. Fit maintains the video inside the frame with borders. Fill crops the video to match the frame without borders.

- Choose between `Fit` and `Fill`
- Color picker for background padding in Fit mode
Live Output Preview in Real-Time

Live Resize Preview - EditKits
One of the best features of EditKits is the live preview panel. As you tweak your resolution, aspect ratio, or stretch settings, you’ll immediately see how the final video will look. This makes it easier to get the result you want without trial and error.
Every resizing job is processed in the background. Launch the job and keep working while EditKits renders your video in the cloud.
Use Case Examples
- Resize horizontal YouTube videos into vertical Shorts
- Convert Instagram Reels into square format for feeds

Automation at Scale with API
If you're a developer or running a media-heavy platform, EditKits lets you resize videos programmatically using our Resize API. Have concurrent jobs, set configurations, and manage processing without ever opening the UI. All of it is fully cloud-native and scalable.
