Screenshot Annotation Tool — Blur, Arrows, FREE

Most screenshots need one quick edit before they’re useful: an arrow pointing at the broken button, a box around the number that matters, a blur over the account ID you don’t want in a bug report.

SuperchargeCapture’s editor opens on every capture and gives you the full markup set with nothing locked. Annotate, crop, then copy or save, with no subscription and no export wall.

The Annotation Tools

Eight tools cover what real screenshots need, each on a single-key shortcut:

• Arrow — point at the exact element you’re talking about
• Box — draw a rectangle to frame a region cleanly
• Ellipse — draw an oval around a face, a logo, or anything round
• Highlight — call out an area without hiding what’s underneath
• Step number — drop numbered markers for a walkthrough people follow in order
• Spotlight — dim the rest of the image so one region carries the whole point
• Text — add a label, a caption, or a one-line note
• Redact — drag over anything sensitive to pixelate or blur it

A Select cursor moves and edits anything already placed, and an object list beside the canvas shows every mark you’ve made. Colour comes from seven swatches picked to stay visible on real UI, plus a custom picker with an eyedropper when you need to match something in the shot.

Add crop with aspect-ratio presets (Original, 16:9, 9:16, 1:1, 4:3, or free-form) and you can trim a capture to exactly the shape you need.

Any Image, Not Just Your Captures

The editor doesn’t require a capture to open. Paste an image with Ctrl/⌘V, drop a file onto the window, or use Import to browse for one, and it loads into the same canvas with the same tools. A screenshot a colleague sent you in chat gets its redaction without a detour through a separate image editor.

Blur Before You Share

Screenshots of dashboards, invoices, settings pages, and inboxes are full of things you don’t want in a public ticket or a shared doc: email addresses, order numbers, names, tokens. Drag over them and they’re obscured in the saved image, as a hard pixelate or a softer gaussian blur. The redaction is baked into the export, not a temporary overlay. It runs entirely on your device, so the unredacted original never gets uploaded somewhere to be processed.

Copy, Save, or PDF

When the markup is done, you have three ways out. Copy to clipboard drops a single-part PNG straight into a chat or doc with one click, the fastest path for a quick “look at this.” Save writes a PNG, JPG, or WebP to disk. And a long full-page capture with several stitched sections can export to PDF, turning a tall scrolling screenshot into a clean, shareable document.

Privacy

Everything in the editor runs locally. The image isn’t uploaded to a server to be blurred, cropped, or annotated — those operations happen in your browser, on your machine. There’s no account, no telemetry, and the capture stays in the browser’s private storage until you choose to do something with it.
