Extend frame turns a portrait shot into a square, a story or a banner by extending the scene around the product instead of cutting into it; the product itself stays untouched. **4** · credits per image · 4K +1 [Start free](https://app.herofab.app/login?lang=en&to=tool-reframe&entry_source=tool) Updated 12 November 2026 ![The same street photo extended to a wide 16:9 frame, the model and the coat unchanged · Extend frame](https://herofab.app/img/ex/coat-wide-1600.webp) Made with Herofab · Extend frame 1. ### Upload the image Any product or on-model image — including one made with Herofab. 2. ### Choose the format 1:1, 3:4, 4:5, 2:3, 9:16, 4:3 or 16:9. 3. ### Receive the image Delivered in 2K, or 4K for one extra credit. ## What you can set. Every option below is part of the Herofab studio. - **Formats:** 1:1, 3:4, 4:5, 2:3, 9:16, 4:3 or 16:9 - **Resolution:** 2K or 4K ## How the frame is extended and what stays in place Extend frame places the source image in the middle of a larger canvas in the chosen format and has the empty margins filled in. The brief is to continue what is already there, the background, the floor, the walls, the surfaces, the light and the shadows, so that the result reads as one wider photograph taken with the same camera at the same moment. The image only grows outwards; nothing is cut from the source to reach the new shape. The tool is also briefed on what to leave out. No people, products, text or other new objects are to appear in the extended area, and the subject is not to be repeated there. The formats run from a square and several portrait shapes to a vertical story, a landscape shape and a wide banner, and the result is delivered in 2K, with 4K as an option. A product photographed on a plain studio ground gives the extension little to guess; a busy street or interior asks more of it. ## When to extend the frame and when another tool fits Extend frame is the right tool when an image is already approved and only its shape is wrong for the place it has to go: a portrait on-model image that is needed as a square listing image, a vertical story or a wide banner for a shop header. Cropping would cut into the garment or the model; extending keeps both whole and adds room around them. The source can be the seller's own photo or an image Herofab delivered. Some jobs sit with a neighbouring tool. When only the pixel size of a sales channel is needed, any delivered image can be downloaded in marketplace sizes without cropping. When the image has the right shape but is too small, Upscale is the step. When the product belongs in a different setting and not in more of the same one, Product studio places it in a new scene. An image that is still to be made can be ordered in the needed format from the start in Virtual try-on, Ghost mannequin or Product studio. ## What to check in the extended image before publishing The join is the place to look first. The original photo meets the new area along its own edges, and that line should not be visible: the tone of the backdrop, the grain of a floor, the line where floor meets wall and the direction of the shadows should all run on without a step. Patterned grounds such as tiles, planks and brickwork are the hardest to continue and deserve a look at full size. The new area itself comes second. The brief excludes added people, products, text and objects, so anything of that kind in the margins is a reason to generate again, as is a second copy of part of the subject. Where a banner or a story will carry a headline, the added space should be calm enough to hold it. The tool has no setting for where the new room goes: the source is placed in the middle of the canvas, which matters for layouts that expect the product at one side. ## Extend frame, answered. **What if the image is already in that format?** Nothing is generated and the credits are returned. **Is the original image redrawn when the frame is extended?** No. Only the new area around it is generated. The original image is placed back on top with a soft blend along its edges, so the product is not redrawn. **Does extending an image increase the product's resolution?** The canvas is delivered in 2K or 4K, but only the new area around the original image is generated. The original product image is placed back on top rather than redrawn. **How do I get a square, story or banner version without a new shoot?** Upload the image to Extend frame and choose the format: 1:1, 3:4, 4:5, 2:3, 9:16, 4:3 or 16:9. Only the new area around the image is generated; the original is placed back on top with a soft blend along its edges, so the product is not redrawn. If the image is already in that format, nothing is generated and the credits are returned. **Can the new area contain a prop or a line of text?** It is briefed not to. The extension continues the scene that is already in the photo, and the tool is instructed to add no people, products, text or other new objects and no text overlay. A headline or a logo is placed on the finished image afterwards, in the layout it is meant for. **Can it complete a product that is cut off at the edge of the photo?** That is not what the tool is briefed to do. It continues the scene and is instructed not to add products or to repeat the subject in the new area, and a part outside the source frame cannot be added back faithfully. The sounder start is a photo in which the whole product is visible. **Is extending an image the same as enlarging or upscaling it?** No. Extend frame gives the image a new shape: the scene is continued around the original, which stays in the centre as it was. Upscale keeps the shape and multiplies the width and the height by two or four. An extended image can be sent straight to Upscale when it also has to be larger. **Where is the new area added when the format changes?** Around the original. The photo is placed in the middle of the larger canvas, and the background, floor, surfaces, light and shadows are continued beyond its edges. Which sides grow depends on the format chosen: a portrait photo turned into a wide banner gains width on both sides, a landscape photo turned into a story gains height above and below. **How much does it cost?** 4 credits per image, plus one credit for 4K. In US dollars that is $0.16 to $0.48 per image before tax, from the largest plan to the smallest credit pack. The cost is shown before you generate, and if a job fails the credits are returned. The 20 free credits at sign-up cover 5 images with this tool.
