Entire landscape retained in its original wide aspect ratio
Proportional scaling retains the complete frame. Width and height change together.
Square crop keeps the central house and removes the outer landscape
A square crop changes which parts remain visible. Padding would retain the whole picture instead.

Understanding resize gif

Animated GIF resizing changes frame dimensions for a smaller or larger animation.

Preserve frame timing and inspect the color palette after every frame has been resampled.

A practical workflow

  1. Choose the required source files, if any. Files are handled as stated in the workspace privacy label.
  2. Set the available controls and apply the operation.
  3. Compare the actual output, check its dimensions and download the generated file.

Decisions and limitations

  • Output width (pixels)
  • Output height (pixels)

Up to 500 frames, 4 megapixels per frame and 40 million decoded frame pixels in total. GIF delays are rounded to 10 ms with a 20 ms minimum; color reduction is lossy.
