Can I convert an image to outline for free?

Yes. The browser preview runs locally and can export a PNG without needing an account. AI enhance is optional and only runs when server keys are configured.

Which image formats work?

The first version accepts JPG, PNG, and WEBP uploads. PNG files with transparent backgrounds work especially well for sticker outlines.

Can I download a transparent outline?

Yes. Turn on transparent output before downloading. This is useful for Cricut projects, stickers, design layers, and product images.

Does the tool support stencil and line drawing styles?

Yes. Use the Printable Stencil and Line Drawing modes to switch from clean outlines to black-and-white craft output or finer line art.

What is Image Outliner?

Image Outliner is an online free image-to-outline converter designed to transform JPG, PNG, and WEBP images into clean outlines, edge maps, printable stencils, sticker-style outlines, and thin line drawings. Operating directly in the browser, its core editor allows users to privately preview and download output files without signing up. For advanced quality or complex assets, it offers an optional AI Outline enhancement to refine images perfectly for coloring pages, tattoo stencils, Cricut projects, laser cutting, and craft templates.

How to use Image Outliner?

To use Image Outliner, upload a photo by clicking, dropping, or pasting it into the workspace. Select your preferred output style (such as Clean Outline, Edge Map, or Printable Stencil), adjust settings like stroke width, smoothing, and edge threshold, and turn on transparent output if needed. Once satisfied with the browser preview, click 'Download PNG' to save your file.
