About this tool
Crop Image lets you select an exact region with a draggable box or precise pixel values, using free or fixed aspect ratios. A circular option outputs a square PNG with transparent corners.
Recommended settings
Settings we suggest
- Use a fixed ratio like 1:1 for avatars or 16:9 for thumbnails.
- Circular crop is perfect for profile pictures — keep it as PNG for transparency.
Supported formats

Quality & file size
Lossy formats (JPEG, WebP, AVIF) trade detail for smaller files as you lower the quality; PNG stays lossless regardless of the slider. The tool always shows the original and result sizes so you can judge the trade-off, and it never recommends a result that is larger than your original as an “optimisation”.
Privacy
Every image is decoded, transformed and re-encoded entirely in your browser using the Canvas API and a Web Worker. Files are never uploaded, are not stored in localStorage, and are cleared from memory when you remove them or close the page.

Common issues & limitations
- There is no true circular image format; circular output is a transparent-corner PNG.
- This tool works on one image at a time.
- All processing happens on your device; nothing is uploaded, so very large batches are limited by your available memory.
Frequently asked questions
Can I crop to a specific aspect ratio?
Yes. Choose a preset like 1:1, 4:3 or 16:9, enter a custom ratio, or crop freely. Exact X, Y, width and height are shown as you drag.
How does circular crop work?
Circular crop outputs a square PNG with the corners made transparent. There is no true "circle" image format, so a transparent PNG is the standard result.
Are my images uploaded to a server?
No. Every image is decoded, processed and encoded entirely inside your browser using the Canvas API. The files never leave your device and are discarded when you close the page.
