About Our Freehand Crop Image Tool
What is freehand cropping? Unlike rectangle or circle crop tools, freehand (polygon) cropping lets you outline any shape by placing vertices. This is ideal for removing irregular backgrounds, isolating subjects with complex outlines, or creating custom avatar shapes that stand out from standard square or circular crops.
Who benefits? Photographers removing distracting backgrounds from portraits or product shots, designers creating custom social media graphics with unique silhouettes, students preparing presentation images that highlight specific areas, and social media users wanting distinctive profile picture shapes all find freehand cropping invaluable.
How the Canvas API polygon crop works — The browser draws the uploaded image to an offscreen canvas. When the user clicks "Crop", the CanvasRenderingContext2Dclip() method restricts subsequent drawing to the polygon path defined by the user's points. The image is re-drawn inside the clip region, and the resulting canvas is exported as PNG with transparency using canvas.toDataURL('image/png').
Zoom for precision — The zoom feature scales the display canvas so users can place points more accurately on fine details. The actual stored point coordinates are always in image (not screen) space, so zooming doesn't affect the crop accuracy — only the ease of placement.
Undo support — Placed a point in the wrong position? The undo feature removes the most recent vertex, letting you iteratively refine the polygon outline without resetting your entire selection. You can undo as many times as needed to get the shape exactly right.
Related tools — After cropping freehand, you may want to further process your image. Use our Rotate Image tool to correct orientation, Flip Image to mirror the result, or Reduce Image Size to compress the PNG for web use.

How to cut an irregular shape out of a photo with freehand crop
A rectangle or circle crop cannot isolate a teapot, a leaf or a person standing at an angle. Freehand crop lets you click points around the part you want to keep. The tool joins them with straight lines into a polygon, keeps everything inside and makes everything outside transparent. The result downloads as a PNG named freehand-crop.png.
This is a manual tool with no AI edge detection, so the cutout is only as good as your clicks. That also makes it predictable: the edge goes exactly where you place it.
Step by step
- Drop a JPG, PNG or WebP file onto the upload area, or click the area to browse.
- Use the minus and plus buttons to zoom between 25% and 400% in steps of 25%. Zoom in on any edge you need to trace closely.
- Click along the outline of the area to keep. Each click adds a dot joined to the previous one by a green line. The first dot is larger and solid green, and the hint under the canvas counts your points.
- Undo Point removes only the latest point, and Clear All removes every point.
- From three points onward, a Close Shape & Crop button appears. You can also click within about 15 pixels of the first dot. A dashed line previews the closing edge.
- Check the result under the Crop complete message, then press Download PNG. Start Over lets you trace again.
When this is useful
- Isolating a handmade product from a cluttered table for a catalogue or marketplace listing.
- Cutting a person or object out for a school project poster, collage or sticker.
- Keeping one oddly shaped region of a screenshot for a presentation slide.
- Making a transparent PNG to lay over another background in a design editor.
- Removing a bystander at a photo edge by tracing around everyone else.
Worked example: Cutting a lamp out of a 1200 x 800 photo
You click six points at (300,120), (620,90), (840,260), (790,610), (450,700) and (260,480), then close the shape. The points span 260 to 840 across and 90 to 700 down, so the output is 580 x 610 pixels. The polygon covers 272,450 of those 353,800 pixels, about 77 percent. The rest, mostly the box corners, is transparent.
Tips for better results
- Place points close together on curves and far apart along straight edges. A curve traced with six points looks like a hexagon.
- Trace a pixel or two inside the true edge. Tracing outside it leaves a fringe of the old background.
- Zoom does not affect the output. The PNG is cut from the original photo at its own resolution.
- The output is trimmed to the bounding box of your points, so there is no large empty margin.
Common mistakes
- Too few points on rounded shapes gives an angular cutout. Zoom in and add points along the curve.
- Clicking near the first dot closes the shape early once you have three points. Zoom in so your start point sits farther from the edge you are tracing.
- Saving the PNG as a JPG afterwards fills the transparent area with a solid colour. Keep the PNG if you need transparency.
- Zooming or pressing Undo Point after the crop redraws the original picture on the canvas. The result preview and download still hold the cropped image. Use Start Over to trace again.
Your files and privacy
The photo is read and cut entirely in your browser using the canvas feature, and the image is never sent anywhere. Opening the page does record which tool was opened, with an anonymous session identifier, but no picture data is part of that.
Frequently asked questions
What size is the downloaded image?
It is the size of the box that exactly contains your points, measured on the original photo. Points spanning 580 by 610 pixels give a 580 by 610 PNG. Zoom only changes how the photo is shown.
Can I move a point after placing it?
No. You can only remove the latest point with Undo Point. If the mistake was several clicks ago, remove those points and place them again, zooming in first.
Why are the edges straight lines?
The tool joins your points with straight segments and has no curve handles. More points give a smoother outline, so a fine outline on a high-resolution photo may need dozens of clicks.
Will it work on my phone?
Taps on the canvas count as clicks, so you can place points with a finger. Precision is lower on a small screen, so use the zoom buttons or a larger screen for detailed shapes.
Is there a file size limit?
The tool sets none, but your browser must hold the full image in memory. Very large photos at high zoom may exceed what a browser can draw, so lower the zoom or shrink the photo first.
