Social media image resizer
Every network wants a different shape. Drop one image, click the part that matters, and get it cut to the four canvases that cover feeds, link previews and stories — in your browser, with nothing uploaded.
Runs in your browser — nothing you type or drop is uploaded.
Which shape for which network
- 1080 × 1350 (4:5) — Instagram and Facebook feed — fills the most feed space.
- 1080 × 1080 (1:1) — Any feed; the safest single shape across networks.
- 1080 × 566 (1.91:1) — X, LinkedIn and link previews.
- 1080 × 1920 (9:16) — Stories, reels and TikTok — full screen.
Questions
What size is an Instagram portrait post?
1080 × 1350, a 4:5 portrait. It takes up more of the feed than any other shape Instagram allows in a feed post.
What size works for X and LinkedIn?
A 1.91:1 landscape — 1080 × 566 here — is the shape of a link preview on both. A 1080 × 1080 square is the safe choice for any feed.
What size is a story or a reel?
1080 × 1920, 9:16 — the full phone screen. Keep text away from the top and bottom, where the app draws its own interface.
Is my image uploaded?
No. It is cut in your browser with a canvas and saved straight to your computer; it never leaves the page.
Can Ravenpost do this for me?
Yes. Upload an image once and the media library cuts it to these same four canvases, cropping on the subject rather than the middle.
