The right size, every platform

Every network wants a different shape — a square post, a tall story, a wide thumbnail. This image resizer lets you hit any of them exactly, either with a one-tap preset or your own pixel values, and crops intelligently from the center so the important part stays in frame.

How to use it

  1. Drop in an image.
  2. Pick a social preset or type custom width and height.
  3. Choose Crop to fill the size exactly, or Fit to keep the whole image.
  4. Export as PNG, JPG or WebP.

Private and instant

There’s no upload step and no queue. The preview updates live as you change dimensions, and the download is generated on your device.

Frequently asked questions

What's the difference between Crop and Fit?+

Crop (cover) fills the whole target size and trims the overflow from the center — perfect for exact social dimensions. Fit (contain) scales the entire image to fit inside the box without cutting anything, which can leave space at the edges.

Will resizing reduce quality?+

Scaling down looks crisp. Scaling far above the original size will look soft, because the tool can't invent detail that wasn't captured. For best results, start from the largest original you have.

Are the social presets up to date?+

They cover the standard recommended sizes for Instagram posts, stories and reels, profile pictures, YouTube thumbnails, X headers, Facebook covers and Pinterest pins. Platforms tweak these occasionally, so the pixel fields let you set anything custom.

Is my image uploaded?+

No. Everything is processed locally with the Canvas API. Your image never leaves your device.
