How this reference is maintained

The values below match the current presets in the browser tool. Platform-owned documentation is linked inside the relevant platform guide where a stable public source is available. Important uploads should still be previewed in the destination app.

Three decisions before every export

  1. What cannot be lost? Products, screenshots, full-body photos, borders, and charts usually need Fit.
  2. What must fill the frame? Feed covers and designed backgrounds can often use Crop.
  3. How different are the ratios? A wide source inside a vertical cover often needs Blur or a separate design.

Testing method

Guide examples are checked against the tool's current Canvas behavior: Crop uses a cover scale and can remove outer source content; Fit uses a contain scale and fills unused canvas with the selected color; Blur keeps a contained foreground over an enlarged blurred background. The safe-area overlay is a 9% inset and is presented as a composition aid rather than a platform rule.

Where to go next

For an immediate export, open the tool. If no content can be lost, start with resize without cropping. If the file looks soft, use the image quality diagnostic. For repeated publishing, follow the one-master, multiple-platform workflow.
