A free browser alternative to Photoshop Content-Aware Scale
Resize photos in your browser and compare the result before downloading.
When this alternative is useful
Try content-aware resizing without installing a desktop editor. This independent tool uses a Rust/WebAssembly implementation based on the open-source caire project. It is not Adobe’s implementation and does not promise identical results. Content Aware Scale is not affiliated with or endorsed by Adobe.
Use it for a quick photo resize when you want local processing, a before-and-after comparison and a downloadable image. Start with a photo containing a clear subject and some quiet background. You can set dimensions, mark regions to protect or remove, and enable face protection.
What you get in this browser tool

What seam carving can change
The algorithm chooses connected paths with relatively low visual energy. Removing those paths changes the image shape. It does not understand every object, so a face, sign, building or repeated pattern can still distort. Protection controls influence the result; they do not lock subjects in place.
This tool scales and carves toward the target. For large aspect-ratio changes, a quality guard can crop part of the source first. Read the result note and compare the full composition before exporting.
Choose a different tool when the task changes
For direct brush deformation, use Liquify Image. For a deliberately melting animation, use Melt Video. For layout with an intact photo and added background space, use Merge Images.
