Memory and frame limits
GIF and editable project imports are limited to 240 frames. The pixel budget is approximately 12 million frame-pixels on narrow/mobile layouts and 48 million on wider/desktop layouts. Pixel budget means width × height × number of frames. Some large images are limited to 4096 × 4096 pixels. Working buffers and undo snapshots need additional memory.
Unavailable features
Cloud synchronization, automatic TIG credit sharing, multitrack video/audio editing, animated WebP export and signed App Store releases are not part of the current verified web editor.
