Crop tool

The crop tool (C) trims the document boundary. Layers outside the cropped area are clipped — their data is preserved on disk so you can re-open the project and re-crop, but they don't render.

#Workflow

1. Press C or pick the crop tool from the rail.
2. Drag a region on the canvas. Or pick an aspect-ratio preset from the right panel.
3. Tweak the box — drag handles, drag the inside to reposition, or punch in numerical width / height / x / y.
4. Hit Apply (or Enter). The document boundary updates and all layers are remapped to the new origin.
5. To cancel without committing, press Esc.

#Aspect-ratio presets

The right panel ships with common ratios:

• Free — no constraint
• Square (1:1) — IG square
• 3:4 / 4:3 / 9:16 / 16:9 — portrait / landscape / story / video
• Custom — type your own w:h

When a ratio is locked, dragging any handle keeps the ratio stable.

#Pending vs. active crop

Internally there are two states:

• pendingCrop — the live drag box you're seeing. It only exists while you're inside the crop tool.
• crop + cropEnabled — the committed crop, applied by Apply.

Switching tools without applying discards the pending crop. Saving the project preserves the active crop (the document remembers its current boundary).

#Re-crop later

Because crop is non-destructive on layer geometry — the editor remaps layer positions to the new origin but doesn't crop the layer pixels themselves — you can always:

• Re-enter the crop tool and drag a different region
• (planned) "Reveal hidden" — extend the canvas back to the original bounds

This is why a tightly-cropped .img is still a perfect creative master — nothing is destroyed.

#Tips

• Crop the canvas, not the layer. To crop a single image, place it on the canvas and use the layer's frame-clip (in the asset edit sheet) instead. The crop tool changes the document size.
• Resize ≠ crop. Use canvas-size (in the file menu / settings modal) to change document dimensions while preserving all layer data; use crop to remove area.
