These sections explain the job in plain language and set expectations for what the tool should do well.
To trace a contour, upload a transparent PNG and the outline finder reads its alpha shape to find the visible edge. You can inset or outset the contour to tighten or loosen the cut line, then export the result in the format you need.
The finder exports a raster contour mask PNG, an SVG path of the contour, or a ZIP that contains both files. That makes it useful for cut lines, masks, and reusable geometry rather than just a visible decorative stroke.
All contour tracing and export run in your browser, so the PNG stays on your device and nothing is sent to a server.
An outline generator draws a visible stroke around an image for presentation, like a sticker border. A contour finder is different: it produces reusable geometry and mask output, which is why it is a separate tool.
Use the contour finder when you need a cut line, a mask, or an SVG path to drive other work. It focuses on a practical contour export from the visible alpha shape, not on replacing a full print-design vector editor.
Short answers for the questions people usually have before trying a utility like this.
Yes. This PNG outline finder is free and runs entirely in your browser with no sign-up.
No. The goal is a practical contour export from the visible alpha shape, not a print-design vector editor replacement.
Yes. The tool exports both a raster contour mask PNG and an SVG path, plus a ZIP that includes both files.
Yes. Contour tracing and export happen in your browser, so the PNG is never uploaded and stays on your device.
Yes. The outline finder runs in any modern browser, including mobile, since all processing is done locally.
