Why CompResızer

Not Just a

Bigger Canvas

Change a comp's dimensions in After Effects and your layers stay exactly where they were half of them now off-frame. Comp Resizer repositions and rescales every layer to fit, so a 16:9 master becomes a clean 9:16 in one click instead of a cropping puzzle.

Nothing to

Set Up

Hours of Resizing

Fill, Fit, or Stretch

Choose how content adapts to the new frame: crop to fill it, letterbox to fit it fully, or stretch to match exactly.

Precise Alignment

A 3×3 anchor grid controls exactly where your content sits in the new frame so you decide what stays inside the visible area and what falls outside it.

Non Destructive

Comp Resizer never bakes, precomposes, or flattens your layers. It temporarily parents them to a rig, applies the new scale and position, then releases the rig your effects and keyframes stay exactly as they were. Every resize runs inside a single undo group: one Cmd/Ctrl+Z and you're back.

FAQ


Yes. Reframing repositions the entire layer stack, including anything animated, based on the alignment and scaling mode you choose.

No. There's nothing to set up. Open any comp even an old one and resize.

No. Comp Resizer is a one time purchase. The version you buy keeps working forever, with no recurring bill.

Updates within your version (v1.1, v1.2, and so on) are free. Major new versions like v2 add significant new features and are optional paid upgrades and as an existing customer, you get discounted upgrade pricing through aescripts. Whatever version you own keeps working regardless.

2D layers are fully supported. For 3D layers, you can currently resize using an experimental method. Since this feature is still in the testing phase, we recommend checking the result at the new size.

Not yet. Comp Resizer works on one active composition per run. Batch reframing is on the roadmap.

Partially yes. You can open your pre-comp and resize it on its own. However, there is no feature to automatically rescale pre-comps within the main composition. That feature is in the roadmap.

Yes. Every resize is wrapped in a single undo step.
