Resize and crop any photo to the exact Instagram post, story or reel cover dimensions.
This tool crops and resizes any photo you upload to Instagram's exact recommended pixel dimensions for square posts, portrait posts, landscape posts, stories and reel covers, then lets you download the result as a PNG file ready to upload.
Instagram compresses and re-crops images that don't match its expected aspect ratios, which can cut off faces, text or logos near the edges of a photo. Preparing an image at the right ratio ahead of time gives you control over exactly what's visible in the final crop instead of leaving it to automatic cropping.
The tool centers the crop on your image: if your photo is wider than the target ratio, it trims equal amounts from the left and right; if it's taller, it trims equal amounts from the top and bottom. For photos where the subject isn't centered, crop the image yourself beforehand so the subject lines up with the middle of the frame before uploading here.
Use the square or portrait options for standard feed posts, portrait for the most vertical feed space, landscape for wide scenic shots, and the story or reel cover option for anything meant to fill a full-screen vertical view.
Instagram Post & Story Size Resizer is built for creators, social media managers, small business owners and marketers who need a quick, reliable way to handle one specific job: resize and crop any photo to the exact instagram post, story or reel cover dimensions. 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.
No. The crop and resize happen entirely in your browser using the Canvas API — your image never leaves your device.
Any image format your browser can display, including JPG, PNG and WebP. The downloaded result is always a PNG.
The current version always centers the crop. As a workaround, pre-crop your source image so your subject sits in the middle before uploading.
The tool preserves the original resolution as much as possible and only scales down to your chosen target size, so quality loss is minimal for typical photos.
