Get a picture to the exact size or aspect ratio you need without squashing it. Ask for a banner, a square, a portrait crop or set pixel dimensions, and the subject stays properly framed and correctly proportioned.
How the ai image resizer works
Upload the image, then say the size or ratio you need, such as '1920x1080 banner', 'square 1:1 with the subject centred' or 'make this 9:16 for a story'. Say whether the canvas should be extended or the shot reframed. Run the tool, check that nothing important was cut off, and rerun on the same upload with a note about what to keep in frame if the crop went wrong.
Tips for the best results
Give exact pixel dimensions or a ratio rather than saying 'bigger'. Name what must stay in frame, such as a face or a logo. Choose canvas extension when you want the whole original kept and reframing when you want a tighter crop. Large ratio changes work better in two smaller steps.
