Image Cropper is a free online tool to crop images with social aspect-ratio presets. It runs entirely in your browser, so your files never leave your device — nothing is uploaded. There's no sign-up, no watermark, and it works on any modern browser on desktop or mobile.
How to use Image Cropper
The Image Cropper trims images to the exact area or aspect ratio you need — square, 16:9, portrait or freeform — with a simple drag-to-position box. It's perfect for profile pictures, thumbnails and social posts. It runs in your browser, so there's no upload and no watermark.

Social-ready ratios
Crop to square, 16:9, portrait or freeform for any platform or profile.
Drag to frame
Position the crop box exactly over the part of the photo you want.
Private and free
Cropping runs on your device — no upload, no watermark.
Crop a photo for Instagram
Reframe any photo for the platform without guessing pixels. Pick the 1:1 square preset for a feed grid, 9:16 for Stories and Reels, or 4:3 for the classic portrait feed, then drag the locked box over the part you want kept. The ratio stays exact as you resize, so nothing gets awkwardly cut off when you post.
Make a 16:9 YouTube thumbnail
Turn a screenshot or still into a properly framed thumbnail before uploading. Choose the 16:9 landscape preset so the crop matches YouTube's player exactly, then position the box over the face or focal point you want front and center. You download a clean PNG at full quality inside the selection, with no letterboxing, no upload, and no watermark.
Trim a screenshot to one area
Cut a screenshot down to just the part that matters before sharing it. Use freeform mode to drag the box around a single button, chart, error message, or chat reply, then crop away the rest. Because it works in your browser on the original pixels, the kept area stays sharp and nothing about the screenshot is sent anywhere.
