The short answer.
The social image resizer crops and resizes your image to exact platform sizes, such as Instagram 1080×1350, stories 1080×1920, YouTube thumbnails 1280×720 and LinkedIn 1200×627, right in your browser. Upload, pick a preset, drag to position, and download a sharp PNG or JPG. Your image never leaves your device.
Why resize before posting
Platforms crop and compress anything that doesn't match their ratio, often cutting off faces, logos or text. Uploading at the exact size keeps control of the composition and avoids extra compression.
Private by design
Everything happens on an HTML canvas in your browser. There's no upload, no server and no watermark, so it's safe for client work and unreleased campaigns.
