Seven brushes, straight arrows and boxes, and five instant board backgrounds — sketch over a photo or start a blank whiteboard, all privately in your browser.
Add one or many — PNG, JPG & WebP. Or paste with ⌘/Ctrl + V
Load your image into PixKit's Draw tool, pick a brush — Pen, Marker, Highlight, Chalk, Neon, Spray or Eraser — choose a size and color, and draw straight on the canvas with your mouse, finger or stylus. Straight lines, arrows, boxes and circles snap in cleanly. Everything runs locally; nothing is uploaded.
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.
Works over your own photo or on a fresh board — no image required.
Drop a photo to draw on it, or click a board to start clean: Whiteboard, Blackboard, Grid paper, Ruled paper or Dot grid. "Keep image" leaves your photo as the surface.
Pick from Pen, Marker, Highlight, Chalk, Neon, Spray or Eraser — or a straight-shape tool (Line, Arrow, Box, Circle) for tidy geometry. Set the size anywhere from 1 to 80 px and pick one of 9 colors or your own with the custom picker.
Sketch with a mouse, finger or stylus. Missed a stroke? Hit Undo. Want a fresh surface? Clear board. When you're done, export the result as PNG, JPG or WebP.
Circle the bug, arrow the button, underline the number — the Pen and Arrow tools make feedback unambiguous in seconds.
No image needed: open the Whiteboard or Blackboard, sketch the idea during a call, and export the board as an image when you're done.
Grid paper, Ruled paper and Dot grid boards give you instant surfaces for diagrams, handwriting practice or math working.
The Highlight brush multiplies color like a real highlighter, so text under the ink stays perfectly legible.
Neon glow strokes, textured Chalk and Spray paint turn any photo into something worth sending.
Answers about drawing, sketching and whiteboarding in PixKit.
PixKit's Draw tool is a full freehand markup surface built on the browser's canvas — not a thin "scribble" widget. It follows your pointer at the image's native resolution, so strokes land exactly where you put them, on a 400-pixel meme or a 4K screenshot alike. And because the drawing happens on your own machine, the picture you're marking up is never uploaded anywhere.
The Pen lays down clean opaque strokes. The Marker is wide and semi-transparent, so overlapping strokes deepen like a felt tip. Highlight multiplies its color into the image — text underneath stays readable, exactly like a real highlighter. Chalk adds grain and dust, Neon glows with a double-pass halo, Spray scatters paint specks, and the Eraser wipes back to transparency. Stroke size runs from a 1 px hairline to an 80 px slab, with 9 preset colors plus a full custom picker.
For tidy markup, switch to the shape tools: drag out a Line, Arrow, Box or Circle and watch it preview live until you release. When you don't have an image at all, one click on a board gives you a Whiteboard, Blackboard (which flips your ink to white automatically), Grid paper, Ruled paper or Dot grid at a sensible resolution — a genuinely useful stand-in for a physical whiteboard on video calls. "Clear board" resets the surface whenever you want a fresh start.
Drawing uses pointer events, so fingers on a phone and pens on a tablet work the same as a mouse. Every stroke is recorded as an undo step; the Undo button in the panel walks back mistakes one at a time. When the sketch is right, export it like any PixKit image — PNG keeps line work razor sharp, WebP keeps it small.
