Image Stretch

The tool performs region-based image stretching in a non-destructive workflow. It accepts a source image and a set of stretch regions defined by anchors; each region can be stretched independently by a specified factor while surrounding areas are preserved. This enables layout adaptation for banners, product pages, or hero images without deforming key content. Edits remain reversible until export.\n\nConceptually, stretching uses a local mesh warp guided by region anchors and weights. An energy-based approach minimizes distortion of important features, while allowing background or peripheral areas to stretch. The algorithm computes a target mesh, applies non-linear interpolation, and outputs a new image at the requested dimensions. Multiple regions can be combined for complex compositions.\n\nWho benefits? Designers, photographers, and marketers needing rapid iterations for responsive layouts and proofing. Use cases include expanding backgrounds to fill banners, reformatting images for social previews, and preserving focal points in product photos when adapting to different aspect ratios. The tool is suitable for freelance work, agencies, and in-house design teams.\n\nUnique value includes non-destructive edits, batch-ready export options, and per-region control that preserves content integrity. Core features include multiple stretch regions, global scale, edge preservation, and fast in-browser processing. Exports support PNG, JPEG, and WebP with adjustable quality; results can be saved as new files while keeping the original image intact for future edits.
