Selection
Mask
A grayscale or painted selection that marks which pixels may be edited.
Use it to protect the rest of an image while changing one area.
edit only inside the mask, preserve everything outside the maskSelection
Inpainting
Regenerates content inside a selected area while using the surrounding image as context.
Use it to remove, repair, or replace a local object or detail.
replace the masked object with a ceramic vase, matching the original lightingCanvas
Outpainting
Generates new content beyond the original image boundaries.
Use it to change aspect ratio, reveal more environment, or create layout space.
extend the scene to the right, continue the same room and perspectiveLocal edits
Generative fill
Fills a selected region with prompt-guided content that blends into the image.
Use it for fast local additions, replacements, and cleanup.
fill the selected area with natural green foliage and matching shadowsLocal edits
Object removal
Removes an unwanted object and reconstructs the hidden background.
Use it when a distraction should disappear without changing composition.
remove the trash bin and reconstruct the wall and pavement behind itLocal edits
Object replacement
Swaps one selected object for another while preserving placement and scene context.
Use it for product variants, props, furniture, or wardrobe changes.
replace the chair with a walnut lounge chair, same scale and perspectiveBackground
Background removal
Separates the foreground subject from its background.
Use it for product cutouts, profile assets, stickers, and compositing.
remove the background, preserve clean hair edges, transparent backgroundBackground
Background replacement
Places the existing subject into a newly generated environment.
Use it to change location without redesigning the main subject.
replace the background with a quiet modern library, match perspective and light directionEnhancement
Relighting
Changes the direction, softness, color, or intensity of light in an existing image.
Use it to match a new background or establish a different mood.
relight the portrait with soft window light from the left, preserve facial identityEnhancement
Color correction
Adjusts white balance, exposure, contrast, and color casts toward a neutral result.
Use it before creative grading or when source colors look inaccurate.
correct white balance and exposure, keep natural skin tonesEnhancement
Upscaling
Increases pixel dimensions while reconstructing plausible detail.
Use it for larger displays, printing, crops, or sharper delivery assets.
Upscaling cannot recover every detail that was absent from the source.
upscale 4x, preserve edges and texture, avoid oversharpeningPreservation
Preserve identity
Keeps recognizable facial structure and identity while other attributes are edited.
Use it for wardrobe, background, lighting, and pose variations of the same person.
preserve facial identity and age, change only the clothing and background
