Seamless Clone / Poisson Blend
Blend one image region into another with seamless Poisson-style compositing for object insertion, cleanup, mockups, and natural-looking edits.
Seamless cloning is useful when a source patch or object should be inserted into a destination image without leaving a hard pasted edge. It fits compositing experiments, product mockups, defect patching, visual prototyping, and browser-based editing workflows where the imported region should inherit surrounding tone transitions and edge continuity.
How to Use Seamless Clone / Poisson Blend
- Upload an image: Upload one of the formats listed by the tool (JPG, PNG, WebP) and wait for the local preview.
- Adjust settings and process: Upload a destination image, choose the blend mode, position the source, and render the seamless composite.
- Review and download: Review the result, then download it in one of the formats offered by this tool.
Controls and Options
Set the clone center over the destination region, adjust source scale, and switch blend mode until the pasted object looks naturally embedded.
Formats and Output
Input: a source image plus a destination image. Output: PNG or JPG sized to the destination image. Blend modes include normal, mixed, and monochrome cloning for compositing workflows.
Why Seamless Clone Is Useful
Seamless cloning is useful when an object, patch, or visual element should be inserted into another image without looking obviously pasted. This helps mockups, compositing, scene cleanup, creative prototyping, and patch replacement workflows where preserving natural transitions matters more than a hard edge cutout.
How It Works
The workflow blends the source region into the destination while respecting surrounding intensity and gradient structure. Instead of only copying pixels, it tries to make the inserted region inherit the local lighting and tonal transitions of the destination scene so the result feels more integrated.
Where It Fits Best
- Product and poster mockups where a source element must sit naturally on a target image
- Patch replacement when covering a defect or replacing a local region
- Creative compositing for fast browser-based experiments
- Visual QA and teaching when comparing blend modes and seamless insertion behavior
Frequently asked questions
What is seamless cloning?
Seamless cloning blends the gradients of a source patch into a destination image so pasted regions look more natural and less like a hard cut-and-paste operation.
When should I use mixed clone?
Mixed clone is useful when strong background texture should remain visible while the source content is blended in. It often works well for textured or detailed backgrounds.
What does monochrome transfer do?
Monochrome transfer uses the structure of the source while adapting tonal behavior to the destination, which can help when color fidelity is less important than texture transfer.
Which image is the source and which is the destination?
Upload the patch or foreground element you want to place as the main image, and upload the background or final scene as the second image. The result keeps the destination size.
Does this run locally?
Yes. The blend is computed directly in your browser via OpenCV WASM without uploading images.
What image formats are supported?
JPG, PNG, and WebP are supported for both source and destination images.
