Paste a screenshot, drop arrows, boxes and callouts on it, and nudge every one into place — 29 shapes that stay movable until you export, with nothing uploaded anywhere.
Add one or many — PNG, JPG & WebP. Or paste with ⌘/Ctrl + V
Paste your screenshot into PixKit with Ctrl/Cmd+V, pick a style — Filled, Outline or Gradient — and click a shape to drop it on the image: arrows in four directions, boxes, circles, speech bubbles, stars, pins and more. Each shape stays a movable, resizable layer until export, and the screenshot never leaves your browser.
Clean the Gemini sparkle, then finish the job — crop, resize, convert and adjust without uploading a single pixel.
Reverse-alpha math restores the true pixels under the Gemini logo — no blur, no AI guesswork.
Crop to any aspect ratio with draggable handles, then resize to exact pixels or quick scales.
Export to PNG, JPG or WebP with a quality slider and a live file-size estimate.
Every tool runs locally with undo/redo. Nothing is uploaded — it even works offline.
Shapes are layers, so you can reposition everything until it's exactly right.
Hit Ctrl/Cmd+V straight from your clipboard, drag the file in, or browse. The Shapes panel is already open on this page.
Choose Filled, Outline or Gradient and a color, then click any of the 29 shapes — directional arrows (→ ← ↑ ↓), squares, rounded boxes, circles, speech bubbles, callout stars, pins, shields and more. Each lands on the canvas as its own layer.
Drag each shape into place, resize from the corners, rotate as needed. Select any shape later to change its style or color live. Export as PNG to keep the annotations razor sharp.
An arrow at the broken button and a box around the error text says more than three paragraphs — and gets fixed faster.
Step numbers, boxes and arrows guide readers through a UI. Outline style keeps the interface visible underneath.
Drop a speech bubble next to the element you're commenting on; pair it with PixKit's Text tool for the words.
Show a customer exactly where to click with one arrow instead of a back-and-forth email thread.
Bursts, stars and bolts draw the eye to the part of the image that matters — gradient style makes them pop.
Practical answers about marking up screenshots.
The frustrating thing about most screenshot markup tools is that every arrow is final: it's drawn into the pixels the moment you release the mouse, so a slightly-off placement means undoing and redrawing. PixKit treats annotations as overlay layers instead. An arrow is an object you can pick up, nudge two pixels left, make bigger, rotate, or recolor — at any point before export. Only when you download does everything flatten into the final image.
The library covers real annotation needs: dedicated arrows pointing right, left, up and down; squares, rounded rectangles, circles and lines for framing; a speech bubble for comments; stars, sparkles, bursts and bolts for emphasis; plus hearts, pins, shields, chevrons, polygons and more. Each drops in with your chosen style — Filled for solid stamps, Outline to frame without covering the UI underneath, or Gradient for a branded look — and any of four preset colors or a fully custom one.
Click any placed shape and the panel becomes its inspector: switching style or color restyles that shape immediately. Stack as many annotations as the explanation needs, reorder your thinking as you go, and use the floating layer toolbar to duplicate or delete. The shape cards even work from the keyboard — tab to one and press Enter to place it.
Annotation rarely travels alone. In the same editor you can crop the screenshot to the relevant region, blur or redact anything confidential before the image goes into a ticket, add text labels next to your arrows, and export as PNG so the crisp UI edges survive. All of it happens locally in your browser — screenshots full of internal dashboards, customer data or unreleased features never touch a server.
