Part V – Editing, Markup, Annotations

At some point, you will want to crop, resize, rotate or annotate your shots. Perhaps you might want to trim your videos, or remove their audio tracks. Read on to learn how ScreenFloat makes this easy and pain-free for you.

Editing, Markup, Annotations

Right-click any floating shot or shot in the Shots Browser to edit it.
By the way, in ScreenFloat 2, you can now duplicate shots, in case you just want to test a crop or rotation, or want to remove audio tracks from a screen recording but still want it around for later.


Cropping allows you to cut out a certain portion of your screenshot or recording.
At the top left, you’ll see the dimensions of your selection, and the current zoom level.

Snap to edges can help you crop at just the right edge of a window, for example.
Hold down the command (⌘) key to temporarily disable snapping while changing the selection rectangle.

While changing the selection rectangle, hold down the option (⌥) key to change its size around its center point.
Click and drag the area of your selection rectangle to move it around.

You can also adjust the rectangle with your keyboard’s arrow keys:
– Up, down, left, right moves the rectangle up, down, left, right by 1px. Hold down the shift (⇧) key to increase it to 5px.
– Up, down, left, right while holding down the option key (⌥) increases or decreases the selection rectangles width or height by 1px. Hold down the shift (⇧) key to increase it to 5px.

Aspect Ratios
In case you’re shooting for a specific aspect ratio, ScreenFloat has you covered for the most popular of them. Right-click the cropping area and select it.


“Folding” is a concept I came up with trying to remove unwanted parts from within screenshots of my apps’ App Store pages, like the “Also Included In” bar. By folding, you remove a vertical or horizontal middle section of an image, and stitch the remaining two parts back together, as if nothing was ever in between.
Before I confuse you even more, here’s a video of it in action:

Note how, in the beginning, there is the “Ratings” bar, and the “Also Included In” bar below Yoink’s icon – both of which we don’t need in our screenshot.
So we Crop the shot and select Fold Vertically, which allows me to select a vertical portion of the screenshot I want to remove along the entire width of it. We click Fold, and those two bars that were there before are now gone, and the image stitched back together.
We then go in a second time and Fold Horizontally, because the screenshot is rather wide. So we select a horizontal portion along the entire height of the screenshot and click Fold to remove that as well.
Voilá, our finished screenshot! And we didn’t have to manually fumble around to re-align things.

Folding is only available for image shots.

Resize and “De-Retinize”

Resizing screenshots is one of the most common things to do, so it better be quick and easy to do.

Width and height are ratio locked when you resize a shot, which means that when you enter a new width, the new height will be auto-calculated for you, and vice-versa.
However, I’ve often been finding myself in wanting to resize to exactly half, or a quarter of the current size. So in ScreenFloat, you can do that, without having to wreck your brain about what half of 180px is. You can just select 50% and it’ll do the math for you.

When you take a screenshot on a Mac’s retina display, its resolution is usually 144 dpi. It leads to a nice and clear screenshot. In some situations, however, you don’t require that high a resolution.
Select Reduce resolution, and it will be reduced down to 72 dpi, leading to a smaller file size, albeit with reduced quality.


There’s not much to say about this one – you can rotate your image- and video shots clockwise and counterclockwise. That’s… it. That’s the feature.

Trim, Remove Audio

Another one of those self-explanatory things.
You can trim screen recordings’ beginnings and ends.

You can also remove a recording’s audio tracks. It is handy when you’ve recorded your microphone along with your recording for internal purposes, but you still want to send the video to someone else. Remove the audio tracks and send it. And if you duplicate the shot first, you’ll still have the original screen recording with the audio track for later.

Annotations, Markup and Redactions

In ScreenFloat 2, you can annotate, markup and redact your screenshots.

All redactions and annotations are entirely non-destructive. That means you can always go back in and make changes to your annotations, or remove them entirely and restore the original shot.

QuickSmart Redaction
Let’s begin with “QuickSmart” redaction. Right-click a text line, face or barcode and redact it without any further effort on your part.
I couldn’t decide between “quick” and “smart”, so I just used both. Names are hard, but I got lucky that time.

QuickSmart-redacting a line of text, a face, and viewing the contents of a QR code.

The type of redaction (blockout, pixellate, blur) used for QuickSmart-redaction is based on what you’ve set up the redaction tool to be when manually annotating. But we’ll get to that in a bit. **

Annotate, Markup, Redact
To begin, right-click a shot (floating, or in the Shots Browser) and select Annotate… .

At the top, you’ll find your tools. From left to right, they are:
– Select: Select, move and manipulate one or multiple annotations space bar on your keyboard
– Freedraw 1 on your keyboard
– Rectangle 2
– Oval 3
– Line 4
– Arrow 5
– Star 6
– Checkmark 7
– X-Mark 8
– Text
– Smart Numbered List
– Highlight 9 on your keyboard
– Redact 0

Double-click any of these tools (or press their number on the keyboard twice) to adjust their properties for future annotations. These are the tool’s defaults and used for every new annotation.
Use the Select tool and double-click an annotation (or multiple) to change their properties. This will only affect them, and not become your new defaults.

In the screenshot above, I double-clicked the Redact tool to be able to switch between the Redaction Styles blockout, pixellate, and blur.
If I choose Blockout, the Blockout Color will come into play, which will be used to completely block the part you overlay with this redaction.
** Like I said above, the Redaction Style you select here will be used for QuickSmart redaction.

The line-based tools (from freedraw to x-mark) all offer the following properties:

– Line Width: How thick a line to draw (1px, 3px, 6px, 9px, 12px)
– Line Style: Solid, dashed and dotted.
– Stroke Color: The color of the line you’re drawing, the rectangle’s bounds or circle’s outline.
– Background Color: A background for the entire annotation, based on its bounding box.
– Fill Color: Rectangles, Ovals, Arrows, Stars, Check- and X-Marks also offer a fill color.
– Rectangle Corners: For rectangles, you can choose between sharp and rounded corners.
– Arrow Style: For arrows, you can choose between “line arrow”, “shape arrow” and “back-and-forth” arrow
– Check- and X-Mark Corners: Choose between sharp, rounded rect, circle or none.

Using freedraw, rectangles, ovals, lines, arrows, stars, check- and x-marks.

Text Annotation
You can change the font, the size, and text- and background colors.

Adding a text annotation, adjusting its text- and background color.

Smart Numbered Lists
This allows you to add self-increasing numbers (or letters) to your image, for example, when writing a mail with instructions on how to perform an action on the computer, you could use this to add steps, like 1, 2, 3, and then reference them in the mail.

Using the smart numbered list tool to add “steps”. Removing one automatically updates the rest.

You can choose between numbers (1-x) or letters (A-Z, then A1, B1, … Z1, A2, B2, etc), and change their borders and colors.

You draw a highlight around an object you’d like to draw attention to, by “tuning out” the rest of the image.

The text above, highlighted with the Highlight tool.

You can change the corners of the highlight (sharp, rounded or oval), and the dimming color (all alpha values supported).

Use the Redact tool to obscure something in a screenshot you don’t wish to share.

Using the Redact tool to blockout, pixellate and blur details in an image.

Please note that researchers have been able to reverse blur- and pixellate effects, so for sensitive information, please consider using blockout.

Use the Select tool to select existing annotations and move them around, manipulate them, or edit their properties.

Editing an already annotated image and changing its redactions, drawing a freedraw line and changing its properties, too.

As you can see above, it’s easy to go back into an already annotated shot and change or remove its annotations, and edit those annotations’ properties with a simple double-click.

– Annotating supports undo and redo. Press command (⌘) – Z to undo, command (⌘) – shift (⇧) – Z to redo, or right-click to reveal the contextual menu and select it there
– With the Select tool, hold down the option (⌥) key on your keyboard and click-and-drag an annotation (or multiple) to duplicate it and its properties (alternatively, select them and press command (⌘) – D)
– Select all annotations easily by click-dragging with the Select tool onto the background, or by pressing command (⌘) – A on your keyboard
– Delete annotations by selecting them and pressing the backspace / delete key on your keyboard
– If you have an iPad and use Sidecar, you can use your Apple Pencil to make annotations, and you can switch between your current tool and the Select tool by double-tapping the Pencil. Hold down the command (⌘) key and double-tap to select the next tool, or hold down the option (⌥) key and double-tap to select the previous tool (from left to right)
– Move annotations around by click-and-dragging them, or with the arrow keys on your keyboard
– Remember that you can always export and drag shots to other apps with and without annotations
– Annotations/markup and redactions are non-destructive – you’ll always be able to restore the original image, or go in and make changes
– Change an arrow’s direction by holding down the option (⌥) key on your keyboard when you start to draw it (video – first we draw an arrow without the option key pressed, then with)
