Quick answer

To annotate a screenshot, paste it into the tool above, pick an arrow, box, text or numbered step, draw, and press Copy image. The annotated copy goes to your clipboard ready to paste into Slack, Jira or an email, or you can download it as PNG, JPEG or WebP. The screenshot is edited in your browser and never uploaded, so it is fine for internal tools.

Before you capture

Hide private details before you mark it up

Bug report screenshots tend to carry a customer's name, an email or an internal URL. Blurr.ing blurs any part of the live web page in Chrome before you press the screenshot key, so the capture never contains it in the first place. Drawing blurs is free and unlimited, and the extension's own capture shortcut can blur more areas on the image afterwards. Then bring the clean screenshot here for the arrows.

  • Draw a box, select text or click an element. Free and unlimited.
  • Screenshots come out with the blurs already in the picture. 5 free, unlimited on Premium.
  • Auto Blur, Blur Text and Tab Privacy hide things for you on every page. Try each one free.

How it works

How to annotate a screenshot online

  1. 1

    Paste or open your screenshot

    Press Ctrl+V or Cmd+V on this page to paste a screenshot from your clipboard, drop an image onto the tool, or choose a file.

  2. 2

    Pick a tool

    Choose an arrow, box, ellipse, highlighter, pen, text or numbered step, plus a colour and a line size.

  3. 3

    Mark it up

    Drag to draw, click to place text or steps. Switch to Select to move or delete anything; Undo and Redo work with Ctrl+Z and Ctrl+Shift+Z.

  4. 4

    Copy or download

    Copy the annotated image and paste it into Slack, Jira, GitHub or a doc, or download it as PNG, JPEG or WebP.

The toolbar

Arrows, boxes, text and highlights

Everything stays editable until you export: select any annotation to move it, recolour it or delete it.

Arrows

Point at the button, the error or the field. Hold Shift to snap to straight angles.

Boxes and circles

Frame a region with a rectangle or ring it with an ellipse. Shift keeps them square or round.

Text

Click to type a label or a note. A contrasting outline keeps it readable on any background.

Highlighter

A translucent marker that tints text without hiding it, the way a real highlighter does.

Numbered steps

Click to drop 1, 2, 3 in order, one badge per step.

Hide

Cover an email or a card number with a solid box or pixelation before you share.

Paste, annotate, copy

From screenshot to ticket in under a minute

Paste the screenshot, mark it up and copy it out. Nothing is uploaded.

Bug reports

Circle the broken element, add an arrow and a one-line note, copy, paste into the ticket.

Docs and how-tos

Numbered steps over a settings screen read faster than a paragraph describing where to click.

Quick replies

Answer "where is that setting?" in Slack or email with a marked-up screenshot instead of a description.

FAQ

Annotating screenshots, answered

How do I annotate a screenshot online for free?
Paste or open the screenshot in the tool above, pick an arrow, box, text, highlighter or numbered step, and draw on it. Then copy the result to your clipboard or download it as PNG, JPEG or WebP. There is no sign-up and no watermark.
Is my screenshot uploaded anywhere?
No. The image is opened and drawn on inside your browser with the canvas API, and the copy or download is created on your device. This page sends no image data to any server, so it is safe for screenshots of internal tools.
How do I add an arrow to a screenshot?
Choose the arrow tool and drag from where the arrow should start to where it should point. Hold Shift while dragging to keep it horizontal, vertical or at 45 degrees. Pick a colour and size first, or select the arrow afterwards to recolour it.
How do I add numbered steps to a screenshot?
Choose the numbered step tool and click where each step happens. The badges number themselves 1, 2, 3 in the order you place them, which makes a screenshot into a short how-to for documentation or a support reply.
Can I paste the annotated screenshot into Slack or Jira?
Yes. Press Copy image and paste it into Slack, Jira, GitHub, Notion, Google Docs or an email. Copying images needs a recent desktop browser; if yours blocks it, use Download PNG instead.
Can I hide private information while annotating?
Yes. The Hide tool covers an area with a solid box or pixelation. A solid box is the safe choice for text such as emails or card numbers, because light pixelation of short text can sometimes be reversed. For a dedicated redaction tool, use the free redact image tool.
Does it work on a phone?
Yes. Choose a screenshot from your photos, draw with your finger, then download or share the result. Pasting from the clipboard works best on a desktop browser.
