The image corner

Crop, rotate and flip an image

Draw the area to keep with a finger, a mouse or the keyboard: every step is announced. The file you get is re-encoded, so all the original metadata disappears, GPS position included.

Drop your image hereOne image, and you will draw the area to keep. Nothing will be sent: the cropping happens here, on your device.Choose a file

This file is beyond what this tool does

This tool needs JavaScript to work, and that is precisely because it works ON YOUR DEVICE: without JavaScript, your file would have to be sent to a server. The instructions and the limits of the tool, however, can be read without JavaScript, just below.

How this is built

Your file never leaves your device

This tool works entirely inside your browser. Not one byte of your file is sent anywhere, and nothing is kept once the tab is closed.

Checkable in ten seconds, without taking our word for it:

Open your browser's inspector: the F12 key (or Ctrl+Shift+I, or Cmd+Option+I on a Mac).
Go to the “Network” tab, then clear the list.
Process a file on this page. The list stays empty: no request goes out.
To go further: cut your connection and do it again. The tool still works.

This absence of requests is also checked BY MACHINE before every release: a lock drives a real browser, processes a real file, and refuses to publish if a single byte goes out.

InstructionsHow it works

Any format your browser can display can be cropped. The OUTPUT format is limited to what your browser can write, and the type obtained is read back rather than assumed.
