Image Cropper
Load an image, drag over the part you want to keep, and download the cropped result as a PNG. Optional aspect-ratio lock for avatars, thumbnails and cover images.
100% private — everything runs in your browser, nothing is ever uploaded.
How to use it
- Load an image — it appears on the canvas below.
- Drag a rectangle over the region to keep; hold the ratio lock for a fixed shape.
- Press Crop, check the preview, then download the PNG.
Why it stays private
Screenshots and photos are frequently private: ID documents, unreleased products, personal photos. Cropping happens with the canvas API on your own machine.
Questions
What does the ratio lock do?
It constrains the selection to a fixed width-to-height ratio — 1:1 for avatars, 16:9 for thumbnails, and so on. The crop follows the shape of the selection box exactly.
Does cropping lose quality?
The cropped region keeps its original pixels — no rescaling happens. But a crop discards everything outside the box, so undo means loading the original again.
Which formats can it read?
Everything your browser can display: JPG, PNG, WebP, GIF (first frame) and more. Output is always PNG; if you need a smaller file, run the result through the image compressor.
