Any image with a clearly visible subject works.
Your browser traces the subject right on your device.
Save the scene, solid cutout, or outline PNG.
The same subject mask produces three different files: one keeps the original scene, one gives you a solid-color cutout, and one keeps only the outer edge. All three are full-size PNG downloads.
The subject becomes a solid color while the original background stays visible. It works well for “Who is it?” games, reveal slides, mystery thumbnails, and any design where the scene is part of the clue.
The subject becomes a colored cutout with a transparent background. Place it in a worksheet, presentation, poster, thumbnail, or moodboard without removing the background again.
The detected subject becomes a clean outer line on transparency. Overlapping subjects share one combined outer edge, while separate shapes keep their own outlines.
Automatic subject detection is fast, but it still depends on the pixels in the photo. These simple choices make ears, hair, tails, wheels, and other thin details easier to separate from the background.
A single person, pet, product, or character with a readable outline is easier to isolate than a crowded group.
A dark subject against a dark wall can disappear at the edge. Different colors or brightness levels produce a cleaner mask.
If an ear, foot, wheel, or tail is cropped out of the source image, the tool cannot reconstruct that missing shape.
Use Smart Brush to mark a missed or extra piece. Start with a Tight range and widen it only when the full part is not selected.
Turn a familiar subject into a visual clue for a party, stream, classroom, or team quiz.
Create shape-matching activities, vocabulary prompts, animal worksheets, and reveal exercises.
Build a recognizable “mystery guest” or “coming next” visual without opening a full image editor.
Use the transparent PNG as a placeholder, a composition element, or a dramatic reveal in a presentation.
SilMaker exports raster PNG files, not vector SVG cut paths. For print production or precision cutting, use the PNG as a starting reference and finish the path in a vector editor.
Learn how to choose a source photo, create a transparent PNG, or export a clean outline without sending your image to a processing server.
Choose a clear subject, convert it online, and correct difficult edges with Smart Brush.
PNG GUIDEMake a background-free colored silhouette for slides, posts, worksheets, and design layouts.
OUTLINE GUIDEExport a transparent raster outline and understand when a vector path is the better choice.
Everything happens inside the browser you’re using now. We don’t upload, store, or send your images to a server.
No. The image is opened and processed in your browser. SilMaker does not receive or store the photo you choose.
You can use JPG, PNG, or WebP images up to 15MB. The downloaded scene and transparent versions are PNG files.
The first run downloads the subject-detection model to your browser. Later runs may be faster because your browser can reuse cached files.
It changes how far Smart Brush inspects around your rough mark. Tight is safer for small details; Wide helps when a larger connected part is missing.
Thin shapes, motion blur, low contrast, reflections, and similar foreground and background colors can make the boundary ambiguous. Smart Brush can correct many local mistakes, but not every image will separate perfectly.
No. It creates raster PNG images at the processed image size. A vector editor is still the right tool for scalable logos, manufacturing files, or precision cut paths.
The tool does not change ownership of the source image. Use photos and artwork you created, licensed, or otherwise have permission to process and publish.
