Social Media Image Resizer: Every Platform Size at Once

How to use the social media image resizer

Upload one image, tick the platforms you post to, and download every correctly-sized version as a single ZIP. Cover mode fills each frame and crops the overflow from the centre; Contain fits the whole image and fills the rest with a colour you choose.

About this tool

Each platform crops uploads to its own aspect ratio, and letting them do it automatically is how heads end up cut off. Pre-sizing your image means you decide what stays in frame.

Cover mode scales the image until it fills the target frame and crops the overflow from the centre, which is the right default for photographs. Contain mode fits the whole image inside the frame and fills the remainder with your chosen colour, which is what logos and product shots usually need.

When to use the social media image resizer

One campaign across every platform

A single hero image becomes an Instagram square, a Facebook link card, an X post and a YouTube thumbnail in one pass.

Open Graph link previews

The 1200 × 630 preset is the widely-supported standard for the picture shown when your link is shared.

Profile and cover art refresh

Header and cover dimensions differ on every platform and are easy to get wrong.

Controlling your own crop

Platforms crop automatically to fit their layout, which is how heads end up cut off. Pre-sizing means you decide what stays in frame.

How it works

Every output is scaled from your original in a single step rather than from a previously resized version, so a 1080 px square and a 2560 px banner are both as sharp as the source allows. Start from the largest version you have, because the tool can only ever discard detail, never add it.

Cover mode computes the larger of the two scale factors needed to fill the frame and crops the overflow symmetrically from the centre. That is the right default for photographs, but it means the edges of a tall image are lost when producing a wide banner. Contain mode uses the smaller factor so the whole image fits, filling the remainder with your chosen colour, which makes it the right choice for logos and product shots where nothing may be cut.

Files are named with the platform and dimensions, for example photo-instagram-post-1080x1080.jpg, so a ZIP of a dozen variants stays comprehensible when you come back to it a week later.

Common problems and how to fix them

Heads or important detail got cropped: Cover mode trims from the centre, which loses the edges when the target ratio differs sharply from your source. Use Contain, or crop deliberately first with the Image Cropper.
The output looks soft or pixelated: Your source is smaller than the target. YouTube channel art at 2560 × 1440 needs a source at least that large, because upscaling cannot add detail.
There are coloured bands around my image: That is Contain mode. Set the background colour to match your brand, or switch to Cover to fill the frame.
The platform still cropped my image: Some placements crop differently across devices. Facebook covers in particular render differently on mobile and desktop. Keep critical content away from the outer edges.
The sizes look out of date: Platforms adjust their layouts periodically. These are the current widely-recommended dimensions; check the platform's own help pages for anything critical.

Frequently asked questions

What size should an Instagram post be?

1080 × 1080 px for square, 1080 × 1350 for portrait (which occupies the most feed space), and 1080 × 1920 for stories and Reels. All three are presets here.

What is the correct YouTube thumbnail size?

1280 × 720 px, 16:9, under 2 MB. Keep important detail away from the bottom-right corner, where the duration badge covers it.

What is an Open Graph image?

The preview picture shown when your link is shared on social platforms or in chat apps. 1200 × 630 px is the widely-supported standard, referenced from your page with the og:image meta tag.

Will my images be cropped?

In cover mode, yes. The overflow is trimmed from the centre so the frame is filled. Choose contain if nothing may be cut, and pick a background colour for the resulting bands.

Do these sizes change?

Platforms adjust their layouts periodically. These are the current widely-recommended dimensions; check the platform's own help pages if you are producing something critical.

Should I use cover or contain?

Cover for photographs, where filling the frame matters more than keeping every edge. Contain for logos, product shots and anything where cropping would remove essential content.

Can I add my own custom size?

Not in this tool. Use the Image Resizer for arbitrary dimensions. The presets here cover the standard placements across the major platforms.
