Resize one image to dozens of exact social media dimensions across every platform.
This tool resizes and center-crops one image to the exact recommended pixel dimensions for a wide range of placements across Instagram, Facebook, X, LinkedIn, YouTube and Pinterest, so you can prepare one photo for several platforms without switching tools.
Every platform and placement expects a different aspect ratio: a YouTube thumbnail is wide, a Pinterest pin is tall, a Twitter header is very wide and short, and an Instagram story fills a full vertical screen. Posting the same untouched image everywhere usually means it gets stretched, squeezed or cropped in ways you didn't choose.
This tool covers the full range of platforms and placements in one dropdown, including cover photos, headers and thumbnails, while the dedicated Instagram Post & Story resizer on this site focuses only on Instagram's own post and story formats with a simpler preset list.
Start with the highest-resolution version of your image you have, since the tool can crop and scale down cleanly but can't add detail to a low-resolution source. For text-heavy graphics like YouTube thumbnails or Pinterest pins, keep important text away from the very edges, since the center-crop may trim a small margin depending on your source image's proportions.
Social Media Image Resizer (Multi-Platform) is built for creators, social media managers, small business owners and marketers who need a quick, reliable way to handle one specific job: resize one image to dozens of exact social media dimensions across every platform. Instead of digging through a bloated all-in-one dashboard or installing a browser extension, you get a single focused page that does exactly this one thing well, works the same way on desktop and mobile, and keeps your inputs on your own device rather than sending them anywhere else. If this is a task you find yourself repeating every week, bookmark this page so it's one click away next time you need it.
Whatever this tool hands you — text, an image, a calculated number, or a piece of code — treat it as a strong first draft rather than a final answer. Skim the result against the specific post, account or campaign you're working on, adjust anything that doesn't quite match your usual voice or brand, and only then copy it into the platform you're actually posting to. Because everything here runs locally in your browser, you can safely try several combinations of inputs back to back without worrying about rate limits, accounts, or data being logged anywhere — refresh the page any time to start over with a clean slate.
Select one platform size, resize and download it, then choose the next size from the dropdown and resize the same uploaded image again — no need to re-upload.
It crops your image around the center to match the target aspect ratio, then scales it to the exact target pixel size — it never stretches the image out of proportion.
The tool works with any image your browser can open, though very large files may take a moment longer to process since everything runs on your device.
