How do I crop an image?

Add one image, move the frame, and press Download crop. Drag inside the frame to move it, drag a handle to change it, and drag outside it to pan. The number under the picture is the export, in source pixels.

What is the difference between crop and resize?

Crop leaves out the pixels outside the frame. Resize changes the width and height. If you need both, crop the subject first, then set the pixel size.

Does 1:1 mean 1080 by 1080?

1:1 means the frame is square. On a 320 × 200 photo the square started at 184 × 184. Set an exact pixel size on Resize image after you crop.

Does cropping make the file smaller?

The byte size can go either way, because the file is encoded again and fewer pixels may remain. JPG and WebP are written at quality 92. For a size in kilobytes, use Compress image.

Can I crop a transparent image or an animation?

PNG and WebP keep transparent pixels. JPG paints them white. A GIF or an animated WebP contributes its first frame as a still image. This page crops one image at a time.

Is the photo uploaded?

The crop runs in your browser. A test JPEG’s camera make, model, time, location, and orientation tag were omitted from the download. A temporary copy stays on this device only if you send the result to another tool.

Crop an image to the part you keep

How to crop an image

Add one image. The frame opens as a square on the upright picture. Clear removes it.

Use Browse files, or drop the image. A new file replaces the one that is open.
Ratio starts on 1:1. The other choices are Free, 4:5, 16:9, 9:16, 3:2, and 2:3.
Drag inside the frame to move it. Drag a handle to change its edges. Drag outside the frame to pan the photo. With the picture focused, the arrow keys move the frame by one source pixel, or by ten with Shift. Plus and minus change the zoom.
Zoom runs from 1 to 4. It makes a small area easier to place. The exported width and height stay on the source pixels inside the frame.
Rotate turns the picture 90 degrees clockwise, swaps its width and height, and places a new starting frame. Center moves the current frame to the middle. Reset builds that starting frame again for the ratio that is selected.
Output is JPG, PNG, or WebP. It starts as the type you opened. A GIF starts as JPG.
Press Download crop. The card shows the original size and the cropped size.

What the frame keeps

Cropping keeps the pixels inside the frame and leaves out the pixels outside it. The download is that rectangle at its own pixel size.

On a 200 × 100 test image, Reset with 16:9 selected exported 164 × 92. The left of that file was the left side of the image, and the right was the right side. A 320 × 200 photo opened on 1:1 at 184 × 184. Both results were the selected source pixels.

The frame stays inside the photo. Free lets each edge move on its own. A locked ratio keeps the shape while you drag. The exported width and height are whole pixels, so a named ratio can be off by about a pixel.

Crop, resize, and a platform size

Crop answers which part of the image stays. Resize answers how many pixels wide and tall the file should be. If you need both, crop the subject here, then set the pixel size.

Ready-made pixel sizes for a specific platform are on Social Media Resizer.

Compared	Crop image	Resize image
What you choose	The area that stays	Width and height
Pixels outside the frame	Left out	Kept, unless that tool is set to Fill and crop
A ratio such as 16:9	A shape for this frame	The relationship between the width and height you set
A usual next step	Resize, when the file must be an exact pixel size	Crop, when the subject is in the wrong place

A ratio is a shape

1:1 is a square. 4:5, 2:3, and 9:16 are taller than they are wide. 3:2 and 16:9 are wider than they are tall. A ratio is the relationship between width and height. 1:1 can be 184 × 184. It is not a fixed size such as 1080 × 1080. 16:9 is not a fixed size such as 1920 × 1080.

Choosing a ratio reshapes the frame you already have, around its center. Reset builds a centered frame of that ratio at about 92 percent of the photo. Free leaves the frame where it is until you drag it. Reset on Free pulls the frame in by about 8 percent from each edge.

The pixel size of the download is whatever rectangle you export. Read that size on the card. To make the file a different width and height after the crop, use Resize image. To read a size without changing it, use Image dimensions.

Where to put the frame

Keep the subject inside the frame, and leave out the edges you do not need. The preview draws a three-by-three grid as a guide while you drag. You place the subject yourself.

Use a square when the destination is square, 16:9 when the slot is wide, and 9:16 when the slot is tall. The destination’s pixel size is a separate step.

The file that downloads

The kept pixels are copied at their own size. Zoom does not enlarge them. JPG and WebP are then encoded at quality 92, so that download is a new file. PNG is written as PNG. On a transparent test image, the PNG crop kept the clear pixels and the original green. The JPG of the same crop painted the clear pixels white.

A GIF contributes its first frame only, and the download is a still JPG unless you choose PNG or WebP. An animated WebP becomes a still WebP of its first frame.

A sideways JPEG is opened upright before you crop. A 320 × 200 test file stored with its camera orientation set to rotate it was 200 × 320 in the tool, and the download was that upright crop. The download omitted that file’s camera make, model, time, location, and orientation tag. A color profile embedded in a source JPEG was omitted as well. A JPG saved here can still include a small profile added by the browser’s encoder.

The byte size can go either way. A flat 320 × 200 JPEG of 3267 bytes became a 184 × 184 JPEG of 978 bytes. A transparent PNG of 171 bytes became a 37 × 37 PNG of 194 bytes. A kilobyte target belongs on Compress image. A different format, without another crop, belongs on the converter.

One image, on this device

The crop uses the picture in front of you. A second file replaces it.

JPG, JPEG, PNG, WebP, and GIF. A file that is not an image is refused. An iPhone photo saved as HEIC belongs on the HEIC page first.
One image at a time.
Each file can be up to 25 MB. A side longer than 12,000 pixels is refused. The cropper keeps the decoded pixels and does not shrink the photo down to that limit.
The image is cropped in your browser. PixZeno does not receive it for cropping. If you send the result to another tool, this browser keeps a temporary copy on this device so the next page can open it. Clear images saved in this browser, in the footer, removes that copy.
