How to crop and annotate a screenshot
A useful screenshot shows only the important area and makes the next action easy to see. Crop first, then add a small number of clear annotations.
Updated:
Crop during capture
Windows + Shift + S avoids an extra crop step: choose Rectangular mode and drag around the final area. This is fastest when the subject is already visible.
Crop an existing screenshot
Open the image in Snipping Tool or Paint, select the crop control, adjust the frame, and save a copy. Keep the original when you may need the surrounding context later.
Add annotations that remain readable
Use one accent color, keep arrows short, and place text beside rather than over important content. Blur or pixelate account names, email addresses, tokens, and other information that should not be shared.
Edit annotations before export
KKSnap annotations remain selectable while editing, so you can move, resize, reorder, or remove them. Export the final image as PNG for interface details or JPEG when a smaller photo file is more important.
