Resizing happens entirely in your browser — the image is never uploaded.

How to Use This Tool

  1. Upload an image from your device.
  2. Pick a platform preset or enter a custom width and height.
  3. Choose cover (fill and crop) or contain (fit and pad).
  4. Click resize, then download the PNG.

What Is a Social Media Image Resizer?

Each network expects images at specific dimensions, and uploading the wrong ratio means awkward cropping or letterboxing. This resizer ships with one-click presets for the common sizes — a 1080×1080 square post, a 1080×1350 portrait, a 1080×1920 story, an X header, a Facebook cover, a YouTube thumbnail and a 1200×630 Open Graph card — plus a custom option for any size you type in.

You choose how the image fits the target. Cover scales the photo to fill the frame and crops the overflow, keeping the aspect ratio so nothing looks stretched; contain fits the whole image inside the frame and pads the edges. The work is done by drawing onto an HTML canvas and exporting a PNG, with high-quality smoothing for clean downscaling.

Because the canvas runs locally, your image is never uploaded — useful for personal photos or unreleased artwork. The output downloads straight to your device as a standard PNG.

Frequently Asked Questions

Which presets are included?
Common social sizes such as the 1080×1080 square post, 1080×1350 portrait, 1080×1920 story, a 1200×675 X header and a 1640×856 Facebook cover, plus a custom option for any size you type in.
Does resizing happen on a server?
No. The image is drawn onto a canvas in your browser and exported there, so the file never leaves your device — useful for photos you would rather not upload anywhere.
Will my image be stretched?
You can choose to fit the image inside the target (with padding) or fill and crop to cover it. Cover keeps the aspect ratio and trims the overflow so nothing looks squashed.
