Seam Carving
Content-aware image resize with seam carving. Remove or expand along low-energy paths, visualize seams.
Seam carving resizes images along low-energy paths rather than uniformly scaling. Remove unimportant regions (sky, flat walls) while preserving people and objects. Visualize the carved seams, then export the resized result.
How to Use Seam Carving
- Upload an image: Upload one of the formats listed by the tool (PNG, JPG, WebP) and wait for the local preview.
- Adjust settings and process: Adjust the available controls, then run the selected image processing workflow in your browser.
- Review and download: Review the result, then download it in one of the formats offered by this tool.
Frequently asked questions
What is seam carving?
Seam carving is an algorithm that resizes images by removing or inserting 'seams'. Connected paths of low-energy pixels. Content such as people and objects is preserved while flat regions absorb the resize.
What is energy?
Energy represents how 'important' each pixel is. Typically computed from image gradients (Sobel/Scharr). Low-energy pixels (uniform regions) are removed first.
What is forward energy?
Forward energy considers the discontinuity the seam insertion or removal would introduce, producing noticeably fewer artifacts than standard backward (gradient-only) energy.
