Screenshot Annotator

Screenshot Annotator is for the moment you need to show someone where to click. Paste a screenshot with Ctrl+V or ⌘V, or drop one in, then draw arrows, boxes, circles and lines, write labels, add numbered step badges that count up on their own, and colour over a line with a see-through highlighter. It suits support replies, bug reports and how-to guides.

It also covers the private parts. Blur and Pixelate replace the pixels inside a box in the saved file, not just on screen, so an email address or account number can’t be read back out. Spotlight darkens everything except the box you draw, and Crop trims the picture to the part that matters.

How it differs from our other tools: Add Text to Image is for captions, memes and styled lettering on photos, and Blur & Pixelate Image is a dedicated hider with a brush and a background blur. This tool puts all the markup a screenshot needs in one place, with every mark still movable, resizable and undoable until you save. Nothing is uploaded: the picture is drawn by your own browser.

1. Paste a screenshot (Ctrl+V or ⌘V), drop it on the box, or press “Choose a screenshot”.
2. Pick a tool from the bar (Arrow is ready to go) and drag on the picture. Choose a colour and a size (S, M, L or XL) first, or change them afterwards.
3. Use Numbered step and tap where each step happens; Text to type a label, with or without a background pill; Blur, Pixelate or Spotlight to drag a box over an area.
4. Press Select (V), then tap any mark to move it, pull its handles to resize it, or drag the dot in the middle of an arrow to bend it. Delete removes it; Undo and Redo go back and forth.
5. Pick PNG, JPG or WebP and press “Save image”, then “Download picture”. Or press Copy to paste the result straight into a chat or email.

• Arrows with clean swept-back heads, straight or curved; drag the middle handle to bend any arrow.
• Rectangle, ellipse, line, freehand pen and a see-through highlighter.
• Text labels on a rounded background pill, or with a thin outline that reads on any background.
• Numbered step badges that count up by themselves, with a Renumber button after you delete one.
• Blur and Pixelate boxes that destroy the hidden detail in the saved file, with a strength slider.
• Spotlight: everything outside one or more boxes is dimmed, with a darkness slider.
• Crop with handles and a rule-of-thirds grid; marks keep their place inside the crop.
• 8 colour swatches plus any colour, and four sizes that scale to the screenshot’s resolution.
• Select, move, resize, duplicate, delete and nudge marks; undo and redo every change.
• Zoom to fit, 100%, in and out; hold Space and drag to move around.
• Saves PNG, JPG or WebP at full resolution, or copies a PNG to the clipboard.
• Opens PNG, JPG, WebP, HEIC, AVIF, TIFF, GIF, BMP and SVG.

• Press ? (or the Keys button) to see every shortcut. Letters pick tools: A arrow, R rectangle, T text, N step, B blur, S spotlight, C crop, V select.
• Hold Shift while drawing to keep lines and arrows at 45° steps, and rectangles and ellipses perfectly square or round.
• For passwords, codes and account numbers, use Pixelate or Blur with Strength above halfway and cover a little more than the text itself.
• PNG keeps text crisp and suits most screenshots; JPG is smaller when the screenshot is mostly a photo.
