Which SNS sizes are supported?

We include presets for X (Twitter) posts and headers, Instagram square/portrait/story, Facebook posts, LinkedIn posts, and OGP share images. You can select multiple presets at once and export them all in one go.

What is the difference between cover and contain?

Cover scales the image to fill the target size and crops the overflow from the center (no padding, cropped). Contain scales the image so the whole thing fits and fills the leftover space with a background color (padded, not cropped). Use contain when you must not crop the subject; use cover for an edge-to-edge fill.

Can I convert multiple images at once?

Yes. Upload several images, pick the presets you want, and the tool renders every image at every selected size. The results download together as a single ZIP file.

Are my images uploaded to a server?

No. Resizing, cropping, and zipping all happen inside your browser. Your images are never sent to or stored on a server.

Yes, it is completely free. No sign-up and no installation required.

What is this SNS image resizer?

A free, browser-based tool that resizes and crops your images to the exact dimensions each social platform expects — X (Twitter), Instagram, Facebook, LinkedIn, and OGP share images. Upload one or many images, pick the presets you need, choose cover (crop) or contain (pad), and download everything as a single ZIP. All processing happens locally in your browser, so your images are never uploaded.

How to use it

Upload one or more images on the left (drag & drop or click).
Select the SNS presets you need — you can pick several at once.
Choose a fit mode (cover crops, contain pads) and an output format (PNG / JPG / WebP).
Press “Resize & download zip” to get every image at every selected size.

Common use cases

Preparing one campaign visual in every platform's required size at once.
