No, no cloud storage integrations or network transfers are connected, keeping files secure.
Client-side canvas export creates a clean raster output, which strips legacy metadata details by default.
Blur occurs when stretching smaller pictures. Stretched shapes happen when aspect ratios are unlocked.
Limits depend on browser canvas allocations (typically up to 16,000x16,000 pixels on desktop browsers).
Make sure the output format dropdown is set to PNG; JPG does not support alpha channel transparency.
