Image Cropper – Crop Images Online Free
Image Cropper is a free online tool that lets you crop JPG, PNG, and WebP images entirely in your browser using the HTML5 Canvas API. Select a preset aspect ratio (1:1, 16:9, 4:3, 3:2, 9:16) or draw a free crop, then download the result in your preferred format with optional quality control. Nothing is sent to a server.
Your images never leave your device. All cropping is done locally using the Canvas API. No upload, no server, no storage.
Frequently Asked Questions
What image formats can I crop?
The Image Cropper accepts JPG, PNG, and WebP files. You can also choose the output format independently — for example, upload a PNG and download the cropped result as a JPG or WebP.
How do I crop to a specific aspect ratio?
Click one of the aspect ratio presets — 1:1 (square), 16:9, 4:3, 3:2, or 9:16. The crop selection will automatically lock to that ratio. Choose "Free" to draw a crop of any shape.
What does the quality slider control?
The quality slider only applies to JPG and WebP outputs (both are lossy formats). A higher value means larger file size but better visual fidelity. PNG output is always lossless and ignores the quality setting.
Are my images uploaded to a server?
No. The image is loaded directly in your browser and processed using the HTML5 Canvas API. The cropped result is generated locally and available for download via a temporary browser URL. Nothing leaves your device.
What is the maximum image size I can crop?
There is no hard file size limit — the tool processes images entirely in the browser using the Canvas API. Very large images (e.g. 50 MP+) may be slower to process depending on your device, but they are supported. The crop output preserves the original image resolution within the selected region.
