Frequently asked questions
How does the crop decide what to keep?
It takes the largest area of your chosen aspect ratio that fits inside the image, positioned by the focus point you pick (centre by default). Nothing is stretched.
What is the "focus" option for?
It controls which part is kept when the crop is smaller than the image β for example, "top" keeps heads in frame for portraits.
Is my image uploaded?
No. Cropping happens entirely in your browser using canvas β the image never leaves your device.
Which formats can I use?
JPG, PNG, WebP, GIF, BMP and AVIF as input; output is JPG, PNG or WebP.
Cropping changes the shape, not the size on disk
It is worth being clear about what cropping does. Cropping cuts away part of the picture so what remains has the proportions you want, which is about framing. It usually makes the file a little smaller as a side effect, but it is not the tool to reach for when a form demands a file under a hundred kilobytes. For that, crop first to get the shape right, then run the result through the image compressor with the limit you need.
Choosing a ratio
A square, or one to one, is the default for profile pictures and product thumbnails on most marketplaces. Sixteen by nine is the shape of video, presentation slides and most banner images, so it is what you want for a thumbnail or cover image. Four by three is the traditional photograph and still common for print. Nine by sixteen is vertical video and phone wallpapers. Four by five is the tallest shape most social feeds will display without cropping it themselves, which makes it efficient for portraits.
The focus point does the real work
A ratio only tells the tool the shape of the final picture, not which part of the original to keep. Everything else is decided by where you set the focus point. Centre works for a subject in the middle of the frame, but photographs are rarely composed that way. If the person stands to the left, pulling the focus left keeps them in the crop and trims the empty space on the right instead. Setting it deliberately is the difference between a crop that looks framed and one that looks truncated.
Crop before you resize
If you need both a particular shape and particular pixel dimensions, crop first and resize second. Doing it the other way round means the resize fits the whole original into the target box, and the crop that follows then throws away part of what you just resized, so you lose detail twice. Crop, then resize, and the full resolution of the area you kept is available to the resize step.
Nothing is uploaded
The crop is drawn by your own browser onto a canvas and saved straight back to your device. Your photo is never sent to a server, which matters when the picture is a document, an identity card or anything else you would rather not hand to a website.
