Crop images without uploading them
Cropping trims an image down to the region you care about — removing empty space, straightening a composition, or hitting a
required shape like a square avatar. This tool shows your image, lets you drag out a crop box (or lock it to a ratio), then
copies just that region onto a fresh <canvas> at full resolution. It all runs in your browser; the image
is never uploaded.
Tips
- Drag on the image to draw a new crop box from scratch.
- Drag the middle to move the box, and the corners to resize it.
- Pick a ratio first if you need an exact shape — the box will keep it.
- Export as PNG for a lossless crop, or JPG/WebP for a smaller file.
After cropping
Want the result smaller too? Run it through the image compressor or set exact dimensions with the resizer.
Frequently asked
Is my image uploaded anywhere?
No. Cropping happens on a canvas inside your browser tab. The image never leaves your device, and it works with Wi-Fi off after the page loads.
Does cropping lose quality?
The crop itself is lossless — it keeps the original pixels of the selected area. If you export to JPG or WebP, the usual re-encoding applies; choose PNG for a fully lossless result.
Can I crop to an exact aspect ratio?
Yes. Pick a preset like 1:1, 4:3, 3:2, or 16:9 and the crop box keeps that ratio as you resize it.
Does it work on a phone?
Yes. You can drag the crop box with your finger in mobile Safari, Chrome, and Firefox.
