The editor

Editor is the place where you can view and modify captured images, view recorded videos and apply AI features.

A capture open in the Sealshot editor The editor: toolbar, canvas, Info panel, and the recent-captures strip.

Annotation tools

Pick a tool from the toolbar, then draw on the canvas. Left to right:

Select — select, move, and transform objects.
Hand — pan around a zoomed canvas.
Crop — see Crop and resize below.
Pen — smoothed freehand strokes.
Line.
Arrow — one grouped pill holding Line Arrow (straight) and Free Arrow (drawn by hand), with adjustable end-caps and solid/dashed/dotted styles.
Shapes — one grouped pill holding Rectangle and Ellipse.
Text — click to type; a full font picker with rich styling, a weight slider, and per-word colour and size. Typography is remembered per tool.
Step — auto-incrementing numbered badges.
Blur — see below.

Each tool has its own colour, opacity, and stroke controls in the properties panel — and each remembers its last-used style.

An Outline colour chip adds a contrasting casing around pen, line, arrow, shape, step, and text annotations (with its own width control) so marks stay readable on any background.

Annotations can carry a drop shadow (toggle it on, then aim it with the position pad or the eight direction presets). Annotations live on their own layer above the image, reorderable (send forward / send backward) from the properties panel.

Annotations don’t have to stay inside the screenshot. Draw an arrow, line, shape, pen stroke, text box, or blur past the edge and the canvas grows to make room when you finish, so marks that point at the image from outside stay where you put them. A single undo reverts both the annotation and the growth.

The annotation toolbar Each tool carries its own colour, width, and style options.

Move, resize, rotate, flip

Select an object to get resize handles plus a rotate handle. Drag to rotate (hold to snap to common angles), or use the properties panel / right-click menu to set an exact angle or flip horizontally / vertically. Paste keeps an object’s transform.

To select several objects at once, drag a selection box across the canvas — starting from empty canvas or from the margin around the image — and it selects the objects it fully encloses.

A selected object with rotate and resize handles Resize from the handles; rotate from the top handle.

Blur and redaction

Select the Blur tool to hide sensitive content. Choose between:

Gaussian blur — softens the region while hinting at what’s there.
Solid fill — paints over the region so the content underneath is unrecoverable in an exported image. Use this for anything truly sensitive.

Solid fill is an annotation, not a change to the pixels: a .seal package keeps the original capture so your edits stay reversible. Export a flattened image — PNG or JPEG — when you send something out, rather than the editable package.

Blur regions can be a rectangle, ellipse, or a freehand brush. A strength slider controls the intensity (it’s labelled Opacity for Solid fill), and for the brush a width control sizes the stroke.

Gaussian blur and Solid fill compared Gaussian blur hints at what’s there; Solid fill leaves nothing to recover once the image is exported.

Focus area

The focus area adds another layer on top of the captured image. It helps to provide finer level control on the image. By default, it covers the entire image. Drag the viewfinder brackets at the image’s corners and edges inward to adjust its size. Note that it’s non-destructive: the document doesn’t change, and the brackets stay adjustable.

Exports honor it. Export to Image and dragging a capture out of the recent strip produce just the focus area — a crop that exists only in the export, reversible any time by moving the brackets back out.
The Focus button in the zoom cluster zooms straight to it.
Right mouse button pans the image around the adjusted focus area. Note panning works on the image, not the focus brackets
Find in Image can limit its search to it.
The right-click menu can make it permanent with Crop to Focus Area, or clear it with Reset Focus Area.

Focus viewfinder brackets over an image Drag the brackets inward to set a focus area.

Crop and resize

Crop — pick the Crop tool and drag a region. Adjust it (with an aspect-ratio lock when you need exact proportions), then press Return to crop or Esc to abandon — the on-canvas hint spells it out. Cropping trims the document and clips annotations to the new bounds.
Cut, copy, or lift a region — while a crop selection is pending, ⌘C copies the region, ⌘X cuts it out leaving a transparent hole, and ⌘↩ lifts it out as its own movable object over the hole — one undo step reverts both.
Resize — set exact document dimensions from the Resize popover, with units and a ratio lock.
Revert to Original Image returns to the untouched capture at any time.

Insert images

Add another image on top of your capture — a logo, a second screenshot — via File → Insert Image on Canvas… (⇧⌘I), or just drop a file onto the canvas. Inserted images move, resize, and rotate like any other object.

Start from a blank canvas

The editor doesn’t need a capture to start from:

File → New Canvas (⌘N) opens an empty canvas to annotate on.
File → New from Clipboard (⇧⌘N) turns an image on your clipboard into a canvas — available whenever the clipboard holds one.
File → Import to Library… (⌘O) brings existing image files into your library.

The + button on the toolbar offers the same three actions.

Live Capture scenes

A Live Capture opens as a layered scene: each captured window is its own image object, stacked over the desktop wallpaper. Because every window was captured in full, you can rebuild the desktop however you like:

Raise a buried window — select it and bring it forward; its whole contents are there, even the parts that were hidden.
Rearrange and remove — drag windows around, resize them, send them forward or back, or delete the ones you don’t need.
Auto Arrange — with two or more windows, tidy them into a neat, non-overlapping layout in one step.
Export This Window… — right-click a selected window to save just that window as its own PNG.
Revert to Original Image puts every window back where it was captured.

Annotate over the whole scene with any tool, then Export to Image (⌘S) to flatten the wallpaper, windows, and annotations into one picture — just like any other capture.

⌘-scroll zooms toward the cursor from any tool; ⌘+ / ⌘− / ⌘0 zoom in, out, and back to actual size — or type an exact percentage in the zoom field.
Fit, Fit width, Fit height, and Actual size are one click away in the zoom cluster, and the Focus button zooms straight to the focus area if you’ve set one.
Right-drag pans a zoomed image from any tool (a plain right-click still opens the context menu); the Hand tool pans too.

The Info panel

The Info panel on the right shows the capture’s name, dimensions, and its automatic summary and Smart Keywords, plus your own tags and a favorite star — all editable in place. See On-device AI for how the summary and keywords are generated.

The recent strip

A recent-captures strip runs along the bottom of the editor so your latest shots are one click away. Click a thumbnail to open it, right-click for actions, or drag a thumbnail out to Finder, Mail, or any app. Videos show a play badge — click it to play, or click the thumbnail to open paused.

The recent-captures strip Jump between recent captures without leaving the editor.

Undo that survives relaunch

The editor’s undo history is persistent: quit and relaunch, switch between captures, and you can still step backwards (⌘Z) and forwards (⇧⌘Z). It’s a single app-wide timeline covering everything — annotations, resize, enhance, background removal, metadata edits, recordings, and deleting and restoring captures — and each undo shows a brief label naming what it undid, on which item.

Export

When you need a regular image, File → Export to Image (⌘S) writes a flattened PNG; the Copy button puts the flattened image on the clipboard. The editable .seal original stays intact, so you can always re-export later — and for encrypted sharing or video export, see Sharing & export.
