Social media image resizer

Every platform crops, pads or rejects images that are not its exact size, and the specs change often enough that memorising them is not worth it. This page starts you on the Instagram square post preset — pick any other placement from the list below and the same tool loads with the correct pixel size already set.

Every placement, one page each

The widget above resizes to whatever placement is loaded on this page. For a different platform or shape, jump straight to its own preset below — same tool, correct size pre-selected.

Dimensions last verified August 2026. Platforms adjust these specs without much notice — if a size below looks off, check the platform's own upload help page before a high-stakes post.

How to use this tool

  1. Drop your photo

    Add any JPG, PNG or WebP photo — drag it onto the box or tap it to choose one from your device.

  2. Pick a fit mode

    Choose Cover to crop and fill the frame, or Contain to keep the whole photo and pad the edges with a colour or a blurred copy of the image.

  3. Download the exact size

    Check the live preview and file size, then download — the image is already the exact pixel size this placement needs.

Questions people ask

Which social media sizes does this tool cover?

Fourteen placements across YouTube, Instagram, LinkedIn, Facebook, X, WhatsApp, Pinterest and Open Graph link previews — the full list with exact pixel sizes is below. Pick one and the same resizer loads pre-set to that size.

Can I use one photo for several placements?

Yes, but crop it separately for each — a photo framed well as a square Instagram post rarely works unchanged as a 3:1 LinkedIn banner. Visit each placement page and re-crop from the same source photo.

Is my photo uploaded anywhere?

No. Resizing happens entirely inside your browser using the Canvas API — this site has no upload endpoint, and the tool keeps working if you disconnect from the internet after the page loads.

What is the difference between Cover and Contain?

Cover scales your photo up until it completely fills the target frame and crops away whatever does not fit, so the result is nothing but photo, no padding. Contain scales the photo down until the whole thing is visible, then pads the leftover space with a colour or a blurred, zoomed-in copy of the same photo so it still looks intentional.

Do social media image sizes change over time?

Yes — platforms adjust these specs every year or two without much notice. The dimensions on this page were last verified in August 2026; if a placement changes after that, the pixel size and any file-size limit shown above may be out of date, so it is worth a quick check against the platform's current help page before a high-stakes upload.
