Image sizes for every social platform

Every platform resizes whatever you give it. Uploading at the right dimensions means that resize does nothing, which is the only way to keep the image sharp.

Why uploading the wrong size hurts

When you upload an image larger than a platform's display size, it scales it down and re-compresses it, usually aggressively and usually with worse resampling than you would get doing it yourself. Upload something smaller and it scales up, which is worse again — there is no detail to invent.

Matching the target dimensions exactly means the platform has nothing to do, and what you uploaded is what people see.

The sizes

Instagram

Instagram's grid is worth a note: it fills bottom row first, so a nine-tile mosaic has to be uploaded 7, 8, 9 then 4, 5, 6 then 1, 2, 3. Our image splitter numbers the tiles for you and says so on the page.

YouTube

The banner is the one people get wrong. It is displayed at wildly different crops on a phone, a laptop and a television, so anything important has to sit inside that central safe area or it will be cut off for most viewers.

LinkedIn

X

Facebook

TikTok and Pinterest

Marketplaces

Marketplace photos usually need a clean white background. A studio shot can be keyed out with the chroma key tool if the background is a consistent colour; a messy background needs an AI background remover, which is on the way.

Chat and gaming profiles

Two things that apply everywhere

Profile pictures are displayed as circles on essentially every platform, even though you upload a square. Anything in the corners will be cut. Our avatar maker shows the circle while you position the crop.

Every platform strips or ignores your metadata — but not all of them, not on every upload path, and not on the original file if someone downloads it from a direct link. If the photo has GPS coordinates in it, remove them before uploading rather than trusting the platform to.

These specs change. Each is dated on its own tool page, and we re-check them quarterly.
