ImageStretcher

ImageStretcher is an image editing tool. A focused web tool that extends photos to any aspect ratio by generating new AI-filled borders, with ratio presets, edge dragging, optional prompts, multiple variants and PNG, JPEG or WebP export.

ImageStretcher's AI Image Expander is a single-purpose web page for extending a photo beyond its original frame. Instead of cropping the subject, squeezing the pixels or leaving black bars, the tool invents plausible new edges so the picture matches a target shape. It is aimed at people who need one image to fit several layouts: social posts, stories, channel banners, marketplace listings, slides and thumbnails. The workflow is short. A user uploads an image by dropping a file, pasting from the clipboard or pasting a URL, then picks a preset ratio (1:1, 2:3, 3:2, 16:9, 9:16, 3:4 or 4:3) or drags the frame edges by hand. A checkered area shows where the AI will add content. An optional text prompt and an art style setting, which defaults to matching the original, steer the fill. The tool can produce more than one variant, so results can be compared before one is accepted and exported as PNG, JPEG or WebP, with a quality slider for the last two formats. Privacy handling differs from the site's classic Stretch tool, which runs entirely on the device. For AI expansion, a smaller copy of the image is sent to the servers for that request only, and the site states the expanded file is not kept afterward. Usage is metered in credits: the interface shows a cost per generate and a remaining balance, extra variants each cost a full generate, and cost scales with how many sides are added. A trial is possible without an account, and signing in adds a monthly allowance, with a Pro plan and extra credits mentioned. Among alternatives, it sits between full editors that bundle generative fill among many features and general image generators. Its narrow scope is both the appeal and the limit: it only grows the canvas outward, while object and text removal live on separate pages of the same site, alongside a crop tool and the local stretch tool.
