About CompResizer

CompResizer, at aescripts.com, is an After Effects extension by Ali Azem Taş, sold through aescripts + aeplugins. It reframes a composition to another aspect ratio in one click, and every layer repositions and rescales to fit the new frame. The product page describes it as needing no rigging, no rebuilding and no baked precomps.

It runs as a panel that you open from Window, then Extensions, then CompResizer, on macOS and Windows. Each run works on one active composition. The author's documentation says batch reframing is on the roadmap, and describes Adapt 3D layers, its 3D reframing option, as experimental.

Version 1.2, released on November 11, 2026, added After Effects 2022, 2023, 2024 and 2027, so the compatibility list covers After Effects 2022 through 2027. In that version the aspect ratio lock tracks the active composition, the anchor grid shows when an axis is inactive, and an interrupted resize reverts automatically. Dimensions have a 4px lower limit, and a RAM warning appears above 8K. Version 1.1.0, from September 29, 2026, redesigned the interface and made the alignment tool more stable.

CompResizer is a one-time purchase, not a subscription. The author says updates within version 1 are free, and that a major version 2 would be an optional paid upgrade with discounted pricing for existing customers.

Pricing: CompResizer is listed at $29.00 on aescripts as a one-time purchase, and a free trial is available from the product page. The author says a Single User License activates on 2 machines and that updates within version 1 are free. Checked November 13, 2026 at https://aescripts.com/compresizer/.
