Free Carousel Image Resizer
Crop and resize any image to exact carousel dimensions for Instagram, TikTok and Stories. Pick a size, slide the crop into position, download a pixel-perfect PNG.
Free and private. Your image never leaves your browser.
Why use it
Exact platform sizes
One click gives you 1080x1350 (4:5), 1080x1080 (1:1) or 1080x1920 (9:16), the dimensions Instagram, TikTok and Stories actually expect.
You control the crop
Instead of a dumb center crop, a position slider lets you decide which part of the image survives, so faces and headlines stay in frame.
Private, in-browser
Cropping happens locally on your device. Nothing is uploaded to a server, so your photos stay yours.
How it works
- Drop in a JPEG, PNG or WebP.
- Pick a target size and adjust the crop position.
- Download your PNG at exact carousel dimensions.
FAQ
What size should an Instagram carousel be?
1080x1350 pixels (4:5 portrait) is the best choice. It fills the most screen in the feed, and Instagram serves it without cropping surprises. Square 1080x1080 also works but takes up less space.
Can I use one image across platforms?
Yes. Upload once, then export a 4:5 for the Instagram feed, a 1:1 square for X or LinkedIn, and a 9:16 for TikTok and Stories. Re-check the crop position for each size.
Is it free and private?
Yes. The tool is free, needs no account, and runs entirely in your browser. Your image is never uploaded to a server.
Why not just let the platform crop it?
Automatic crops cut from the center, so faces, product shots and text often get chopped. Cropping before you post keeps you in control and avoids blurry upscaling.
