Frequently Asked Questions

Which platforms have preset sizes?

Instagram (post, portrait, story/reel, profile), YouTube (thumbnail, channel art, profile), Twitter/X, Facebook, LinkedIn, TikTok, and Pinterest — each with their own correct dimensions.

What's the difference between Cover, Contain and Stretch?

Cover crops your photo to fill the target size with no distortion. Contain shrinks the whole photo to fit inside the frame, adding a background color around it. Stretch forces the image to the exact size, which can distort the aspect ratio.

Can I resize one photo for multiple platforms?

Yes — select a platform, download, then pick a different platform preset from the same uploaded photo and download again.

Is the social media resizer free?

Yes, completely free with no signup and no watermark.

Is my image uploaded to a server?

No. Resizing happens entirely in your browser using the Canvas API. Your image is never uploaded anywhere.

Square post: 1080x1080px. Portrait post: 1080x1350px. Story/Reel: 1080x1920px. Profile picture: 320x320px (displayed as circle).

What size should a YouTube thumbnail be?

1280x720px (16:9). Keep important content in the centre to avoid being cropped on mobile.

How do I resize for multiple platforms at once?

Upload your image, select each platform preset one at a time and download, or use the batch export to get all sizes in a ZIP.
