Every image size the platforms publish, from their own help and developer pages, checked on 21 October 2026 — with the ones they don't publish marked as such. Then crop and resize a photo to any of them; it's done in your browser and never uploaded.
Cropped and resized entirely in your browser — your photo is never uploaded anywhere.

Not published: Instagram's profile photo size and the shape of its profile grid, organic Instagram and Facebook Story sizes (only the ad specs above), Facebook's event cover, YouTube's profile picture upload size (it shows at 98 × 98), and TikTok's in-app photo sizes. Sizes that appear only in a platform's ads guide are marked "ad spec".
Your photo is cropped and resized on this page. It's never uploaded or saved.
Turn this into a whole campaign
Sized the images? Spotlight's Campaign mode writes the post for each platform to go with them — captions, hashtags and alt text, each inside that platform's limits.
Campaign mode is part of the Spotlight workspace on CAPTD's paid plans — see pricing.
Open Campaign modeLists the image sizes each platform publishes for posts, profiles, covers and banners, with file-size limits and a link to the source. The resizer crops a photo to the exact shape and saves it at the exact size — under the file-size limit where there is one — or every size for one platform at once.
Sizes marked 'ad spec' come from the platform's advertising guide because it publishes no size for normal posts. 'No exact size' means the platform gives a range or a limit, not a size; the note says what it does publish.
Each platform publishes its own sizes, and they change. Instagram now takes feed photos anywhere from 1.91:1 (landscape) to 3:4 (tall) at 1,080 px wide; YouTube recommends 3840 × 2160 thumbnails; LinkedIn's Page cover is 1512 × 256.
This page only lists what each platform says on its own pages, with the date it was checked. Where a platform says nothing — Instagram's profile photo, for example — it says so rather than repeating a figure from a blog.
An image at the wrong shape gets cropped by the platform, often through a face or a headline; one that's too big may not upload, and one that's too small looks soft.
Sizes marked 'ad spec' are from the platform's ads guide because it publishes none for organic posts.
