Social Image Resizer

Turn one campaign image into a coordinated platform set. Choose the focal point once, inspect working safe zones, select output sizes, and export JPG, PNG, or WebP files without uploading the source.

Current presets with room for platform change

Instagram currently preserves photos up to 1080 px wide when their aspect ratio falls between 1.91:1 and 3:4, which is why this tool uses a 1080 x 1440 portrait preset instead of treating 4:5 as the only portrait option. YouTube now recommends very high-resolution 16:9 thumbnails, so its 3840 x 2160 preset is available but not selected by default.

Why one automatic crop is not enough

Square, portrait, wide, and vertical placements remove different parts of the source. A centered crop can cut off a person, product, or logo even when every exported file has the correct dimensions. The shared focal point gives the set consistency, while the active preview makes each composition reviewable.
