Image Outliner

Image Outliner is a straightforward web tool that turns any photo into a clean outline, stencil, or line drawing. You upload a JPG, PNG, or WEBP image, adjust a few controls, and download a transparent PNG — all in your browser with no account needed. It's built for people who need quick outlines without opening a heavy editor like Photoshop or Canva.

The tool gives you several modes: Clean Outline for subject contours, Printable Stencil for bold black-and-white regions, and Cricut Cut Lines for vinyl decals. You can tweak the edge threshold, smoothing, stroke color, and line thickness. A live preview shows edge maps and the final result side by side. Processing runs locally on your machine, so nothing gets uploaded to a server. For cleaner results, there's an optional AI Enhance feature that refines stencils, tattoo references, and high-res exports — but it requires credits and server keys.

Image Outliner is a good fit for crafters working with Cricut or Silhouette machines, tattoo artists drafting stencil references, and anyone making coloring pages from photos. It's also handy for designers who need outline versions of product images or icons fast. The free local tools handle most basic jobs; paid plans add SVG/PDF export, batch processing, and history for more serious use.
