Resize and reframe any photo to the exact dimensions each social platform expects, Instagram, TikTok, YouTube, X, LinkedIn, and more. It runs entirely in your browser, so your images are never uploaded and stay sharp.

How to use Social Media Image Resizer

  1. Choose an image, or drag and drop it onto the page.
  2. Pick a platform and a preset, for example Instagram Feed (1080×1080) or Story / Reel (1080×1920).
  3. Choose how it fits: Crop to fill, Fit with a padded background, or Stretch, then drag the frame to reposition.
  4. Download the resized image, ready to post.

Frequently asked questions

Will resizing reduce my photo's quality?

No more than necessary. The tool uses high-quality Lanczos resampling and lets you set the output quality, so downscaling to a platform size stays crisp. Your original file is never modified.

Are my photos uploaded anywhere?

Never. All resizing happens locally in your browser, your images stay on your device and are not sent to any server.

Which platforms and sizes are supported?

17 platforms with 60+ presets, including Instagram, TikTok, Facebook, X, YouTube, LinkedIn, Pinterest, Snapchat, Threads, and WhatsApp, kept current with each platform's recommended dimensions.
