Fill taller and wider formats without cropping the creative.
A square master rarely survives a story frame or a leaderboard banner. Background expansion rebuilds the canvas around the approved artwork so every ratio keeps its composition, its safe areas and its brand look.
- Subject stays untouched
- Brand backgrounds supported
- Every size editable
- No credit card required · Full per-size control
The subject keeps its proportions; only the surrounding canvas grows.
Cropping loses the composition. Stretching breaks the brand.
Most format changes are not a scaling problem, they are a canvas problem. When the target ratio is taller or wider than the approved master, something has to give: the product gets cut, the logo drifts into the edge, or the artwork is stretched until the proportions look wrong.
Destructive cropping
Cutting to fit removes the parts of the frame the campaign was approved on — usually the product or the call to action.
Distorted scaling
Stretching an image to a new ratio changes proportions and makes typography and logos look off-brand.
Manual rebuilds
Rebuilding the backdrop by hand for every placement is the slowest part of multi-size production.
Extend the canvas, keep the approved subject.
Background expansion treats the approved artwork as fixed and generates only the space around it, so the creative can breathe into the new ratio.

The formats that break a square master.
Expansion is most valuable when the distance between the master ratio and the placement ratio is largest.
- 9:16 story and reel frames
- 4:5 feed portrait placements
- 16:9 landscape and video thumbnails
- Wide display banners
- Skyscraper and half-page units
- Print-adjacent and out-of-home ratios
Expansion is a production step, not an automatic approval.
Every expanded size stays editable. The production team decides whether the extended canvas reads correctly before anything is downloaded.
Per-size review
Open each generated output, adjust the layout and confirm the result before export.
Brand-consistent backdrops
Use Brand Kit colors and gradients so extended areas still match the campaign's visual language.
Ratio-aware layout
Headline, logo and call-to-action positions can be tuned for the new frame instead of inherited blindly.
