What this social media image resizer does

Social Media Image Resizer offers a set of widely used dimensions: square posts, portrait posts, stories, profile pictures, YouTube thumbnails, LinkedIn banners and Open Graph previews. It scales the image to cover the target and crops from the centre.

Platforms change their recommended sizes from time to time, so treat these presets as practical defaults and check the current guidance for a paid campaign. All resizing happens on a canvas in this tab.

Why use it

  • Produce a batch of correctly shaped images from one source.
  • Avoid stretched faces and awkward crops caused by non-proportional resizing.
  • Keep profile pictures and banners consistent across platforms.

How to use it

  1. 1Choose an image.
  2. 2Select one or more presets.
  3. 3Generate the images; each is centre-cropped to fill the frame.
  4. 4Download the files you need.

Worked examples

Square post

Input

A 4000 × 3000 photo

Output

A 1080 × 1080 JPEG cropped from the centre.

Story

Input

A landscape photo

Output

A 1080 × 1920 portrait crop; the sides are cut off.

Common mistakes

  • Using a centre crop for a subject near the edge, which cuts them out of frame.
  • Uploading a tiny image to a large banner slot; resizing cannot add detail.
  • Treating these dimensions as guaranteed current platform requirements.

Frequently asked questions

Can I choose the crop position?
This tool uses a centre crop. Crop the image manually first if the subject is not centred.
What format is the output?
JPEG at quality 0.9, which is widely accepted and small enough for social uploads.
Does it preserve transparency?
No. JPEG has no alpha channel, so transparent areas are flattened. Use the favicon or image resizer tool for PNG output.
Is my photo uploaded?
No. Processing happens locally in your browser.
