Annotate, redact and crop images

The image editor opens as a popup over the gallery. Select a capture and press Enter or E, or double-click it. Edits are non-destructive: the layers are saved beside the image, so you can reopen a capture later and move, restyle or delete any annotation.

When you’re done, click Save & Exit (it reads Close if nothing changed), or Discard to throw away this session’s changes. Esc returns to the Select tool; press it again to close the editor.

Tools

Every tool sits in the toolbar across the top. Its tooltip shows the shortcut.

Tool	Key	What it does
Select	V	Select, move and resize annotations
Box / Circle	B / O	Solid, Shaded, Outline or Hand-drawn shapes
Arrow / Line	A / L	Arrows (Normal or Hand-drawn) and lines, with start and end caps and taper
Draw	D	Freehand pen
Highlight	H	Highlighter marker
Text	T	Textbox, Callout (with a tail) or Outline text
Step	S	Numbered marker (circle, square, rounded square or diamond)
Redact, Blur, Pixelate, Erase	R	Hide part of the image (see below)
Cutout	F	Dims everything outside the region
Magnify	M	A lens that enlarges the area beneath it
Crop	X	Crop the image

The Annotation page of the left panel shows the options for the selected annotation, or for the tool you’re about to draw with. For Draw and Highlight, Smart straightens strokes that read as straight lines and Freehand keeps them exactly as drawn. Hold Option to skip straightening for one stroke. For Step, Number sets the next marker and a reset button starts again at 1.

Redact sensitive information

Choose a method, then drag over the area:

Method	Result
Redact	Averages the area into cells, shuffles them and discards outlier colors. The original layout is destroyed.
Blur	Gaussian blur.
Pixelate	Classic pixelation.
Erase	Replaces foreground (like text) with the surrounding background, which is handy for clean mockups.

Intensity means something different for each method: darkening for Redact, blur amount for Blur, block size for Pixelate, and erase strength for Erase.

Auto-Redact scans a capture for secrets: API keys and tokens, passwords, credit card numbers, SSNs, email addresses, phone numbers, IP addresses and webhook URLs. Right-click a capture in the gallery and choose Process → Auto-Redact. Review the matches in Auto-Redact Results and click Redact Selected. The result is saved as a new image with the redactions baked into its pixels.

Crop

Press X and drag. Hold Shift for a square crop, or Option to turn off edge snapping. Press Enter to apply, Esc to cancel, or R to reset to the whole image.

Layout, background and color

The other pages in the left panel restyle the whole picture:

Layout: pick the canvas shape (for example 16:9, 1:1, 4:5 or 9:16) and set the picture’s size, position, corner rounding and border. The export size and shape also appear at the bottom right of the editor.
Background: turn on Show Background to put a background behind the picture. It’s included in the export.
Color: presets plus Exposure, Contrast, Saturation, Warmth, Grain and Vignette. Reset grade returns to neutral.
Layers: reorder or delete layers.

Editing shortcuts

Action	Shortcut

See Keyboard shortcuts for the full list.

⇧⌘E (Export as PNG…) saves a flattened PNG with no editing data.
⌘C copies the image, ⌘E opens Share, and ⌘P prints.
Right-click the canvas for Flip, Rotate 90°, Remove Background, Extract Color Palette… and Copy to Clipboard.
The Export dialog offers PNG, JPEG, WebP, PDF (each page of a multi-page document becomes a PDF page) and SuperCapture Archive formats. It also has settings for dimensions, quality, padding and frame.
