How to Resize Images for Social Media
Learn how to resize one image for all social media platforms at once using ShareMint.
Resizing one photo for Instagram, X, TikTok, YouTube, LINE, and every other platform used to mean opening a different tool (or paid app) for each size. ShareMint collapses that into a single workflow: upload once, pick every preset you need, and download the entire set as a ZIP. Everything runs inside your browser, no sign-up, so you can go from raw image to publish-ready assets in under two minutes.
Steps
Upload your image
Open ShareMint and drag & drop your image, or click to select a file. You can also paste from clipboard with Ctrl+V / Cmd+V.
Select SNS presets
Choose the platforms you need — Instagram, X (Twitter), TikTok, YouTube, LINE, and more. Select multiple presets to resize for all at once.
Set focal point (optional)
Click on the important part of your image. ShareMint will auto-adjust the crop position for each preset to keep your subject centered.
Resize and download
Click "Resize & Export" to process all selected sizes. Download individually or as a ZIP file.
