Editing Tools

Remove backgrounds, upscale, and expand images with AI.

Edit images using natural-language prompts through the Pixa MCP server. All results are saved to your workspace.

Background removal

Use edit_image with action: "remove_background":

Remove the background from this product photo.

The output is a transparent PNG with the subject cleanly isolated. Supports batch processing — pass an array of images to process them in parallel.

Upscale

Use edit_image with action: "upscale" and optional scale parameter ("2" or "4"):

Upscale this photo to 4x.

Expand / outpaint

Use edit_image with action: "expand". You can specify pixel amounts per direction (left, right, top, bottom) or use aspect_ratio (e.g., "16:9") to auto-calculate the padding:

Expand this square image to 16:9 for a website banner.

Chaining operations

Run multiple editing steps in sequence by passing the output asset ID of one step into the next.

Remove the background from this product photo, then upscale the result 4x.

The agent will call edit_image (action: remove_background), then call edit_image again (action: upscale, scale: "4") with the resulting asset ID.

For repeatable multi-step workflows, consider creating a pipeline instead.

Batch editing

The edit_image tool accepts an array of images for batch processing:

Upscale all the images in my 'Product Shots' collection to 4x.

The agent calls assets to list the collection contents, then edit_image with an array of asset IDs.
