Remove backgrounds from images with smart edge detection. Supports color picker, corner detection, and preset colors with adjustable tolerance.
Separating a foreground subject from its background is one of the classically hard problems in image processing. Simple approaches like color keying (chroma key) only work against controlled backgrounds, green screens, solid studio seamless. Real photos have subjects against complex, varied backgrounds with subtle color overlaps, shadows that belong to the subject but match background tones, and hair or fur edges where individual pixels contain blended foreground and background colors. Modern browser-based background removers use trained segmentation models, typically based on U-Net architectures, that predict a per-pixel alpha mask from learned features rather than color rules. This tool produces PNG output with an 8-bit alpha channel, which gives 256 levels of transparency per pixel rather than just binary on/off. That matters most at subject boundaries: soft edges, motion blur, and fine detail like hair or fur need fractional alpha values to composite correctly onto new backgrounds. A binary mask tends to produce the harsh cutout look of an early 2000s Photoshop job; a continuous alpha mask lets the result blend into any background without visible edge artifacts at normal viewing sizes.
Initializing in your browser…
Strip EXIF, GPS, camera data and other metadata for privacy. Features selective removal, batch processing, and metadata preview before removal.
Convert images to Base64 encoded strings for embedding in CSS, HTML, or JavaScript. Multiple output formats available.
Compare two images pixel-by-pixel. Multiple comparison modes: side-by-side, overlay, difference highlighting, onion skin, and slider. Perfect for visual regression testing.
A product shot needs its busy background removed so it can sit on a clean white PDP.
Input
sneaker.jpg (cluttered desk background)
Output
sneaker.png with a transparent cut-out, edges refined
A segmentation model isolates the foreground subject and outputs an alpha-masked PNG you can drop onto any background. It runs in the browser, so product imagery is not uploaded to a third-party service.

The removal pipeline runs a neural segmentation model in-browser, producing a probability mask for each pixel (how likely is this pixel to be foreground?). That probability is then thresholded and refined into a final alpha channel. Models trained on portrait and product photography handle those cases well, crisp edges on torso and limbs, clean cuts around product packaging, but they struggle in predictable places: hair against a complex background, translucent materials like glass or chiffon, and scenes where the subject-background distinction is ambiguous (a person standing in a crowd, for instance).
Two modes handle different inputs. AI mode runs the neural model and works best on photos of people and products; the first time you use it the model (about 30 MB) downloads to your browser, then runs locally on subsequent images. Color mode is built for solid or near-solid backgrounds: you pick the background color with an eyedropper and widen or narrow a tolerance slider to control how aggressively similar pixels are knocked out, which is faster and more predictable than the model on flat backdrops. After removal you can preview the cutout against a solid color, a gradient, a blur, or your own replacement image before exporting.
A few honest limitations worth flagging. The tool cannot recover foreground detail that was never visible in the source, if hair was shot against a similar-colored background and the camera could not separate them, no amount of processing will. Reflections and shadows cast by the subject onto the background are discarded along with the background; if you need a realistic composite, you will need to paint new shadows at the compositing stage. And very high-resolution images (above about 4000 pixels on the long edge) are downscaled for the segmentation pass and then the mask is upscaled back; this is fast but can produce slightly softer edges than running at full resolution.
In AI mode, photos with good subject-background separation produce the cleanest cutouts. In Color mode, a solid, evenly lit background (like a green screen or seamless) works best.
No. Your image is processed entirely in your browser and never leaves your device. On first use of AI mode the segmentation model (about 30MB) is downloaded from a CDN and cached for next time.
Use Color mode and tune the tolerance so only the background color is removed, or composite the cutout onto a replacement background in the preview.
PNG with an alpha channel for transparency.
AI mode handles most cases reasonably well. Very fine hair against a complex background can still be tricky; a cleaner or more uniform background gives the best edges.
