Using Canvas Editor for Images

Use this guide when you want to manually adjust the layout of an image in Riverflow.

The canvas editor is a layer-based editor. Use it when you want to move, resize, rotate, arrange, or add visible elements yourself.

Use Performing AI Edits on Images instead when you want Riverflow to change the image content from a prompt.

Use the canvas editor when the image is broadly right and the layout needs manual control.

Canvas editing is useful for:

Canvas editing is not the best tool for changing the actual image content. If you need to remove an object, change a product detail, replace a prop, or alter the background naturally, use Quick edit, Swap products, or Fix product details instead.

You can open the canvas editor from an existing image where the Editor action is available, or you can start from the Editor area.

To edit an existing image:

To start from a blank canvas:

The canvas is built from layers. A layer is an editable element on top of the canvas, such as the original image, a text block, a logo, or another image.

Use the layers panel to manage what appears in the final image.

Depending on the selected layer, you may be able to:

If you cannot select something on the canvas, check the layers panel. It may be behind another layer, hidden, or locked.

Use text layers for short copy, labels, calls to action, claims, badges, or simple layout text.

Custom brand fonts can be uploaded where the font selector supports them. You are not limited to Google Fonts.

Keep text away from the very edge of the canvas unless the design deliberately needs edge-to-edge copy.

Use logo and image layers when you want to add brand marks, product cutouts, badges, pack shots, campaign graphics, or supporting visuals.

Check that logos are not stretched and product images are not distorted.

Use canvas size controls when the final asset needs a specific format or pixel dimension.

You can use canvas sizing to create assets for formats such as square, portrait, landscape, paid social, email, PDP, or landing page placements.

When changing canvas size, check:

Changing canvas size controls the layout area. It is not the same as using an AI aspect-ratio edit to naturally extend or reframe the image. If you want Riverflow to generate new visual space around an image, use Change aspect ratio from the image preview or Batch.

Use the background colour control when the canvas background should be a flat colour.

This is useful when you are building a simple composed image, product card, end card, or layout with transparent or cutout assets.

If you need Riverflow to change the background inside the actual image, use Quick edit or a relevant Batch action instead.

When the layout is ready, save the image.

Before saving, check:

After saving, open the edited result and download it in the file format you need.
