Image crop and resize

Cropping, resizing, and file size are different

Cropping removes the part of the picture outside a rectangular frame. Resizing changes the number of pixels in the saved image. Neither setting directly targets a file-size limit; the output size also depends on its format and image content.

For example, start with a 4000 × 3000 image. A 3000 × 3000 square crop removes 500 pixels from each side. Saving that crop at 1080 × 1080 reduces its dimensions as well. The crop decides what stays in frame; the output dimensions decide how many pixels the saved copy has.

If an upload form specifies a maximum file size, check the actual downloaded file after cropping. A smaller image often takes less space, but this tool does not set a target size in KB or MB.

Choose an aspect ratio that fits where the image will go

Use Freeform when you need to frame a particular subject. Original image ratio keeps the source proportions. The other presets are square 1:1, landscape 4:3, landscape 16:9, and portrait 9:16.

A ratio describes width compared with height. A square crop can work for a profile tile, while a landscape frame may fit a slide or video thumbnail. Check the destination's current requirements before you choose; the crop presets do not guarantee that a third-party site will display the whole image.

After choosing a ratio, drag inside the frame to move it. Drag the lower-right handle to change its size. The selection stays inside the source image, so check that faces, labels, or other details are not too close to an edge.

Use coordinates for a repeatable crop

For a screenshot series with the same pixel dimensions, enter the distance from the left and top edges, then the crop width and height. Coordinates begin at the source image's top-left corner. Select “Apply crop area” before generating the output.

For example, on two 4000 × 3000 screenshots, an area starting at X = 500 and Y = 300 with a width of 3000 and height of 2250 selects the same rectangular region in each file. Load and crop one image at a time, and confirm that the next image has the same dimensions before reusing those numbers.

When a ratio is selected, the height follows the width and the height field is disabled. If you need to enter both dimensions independently, choose Freeform first.

Set the output dimensions after framing

Changing the crop area resets the output width and height to the crop's pixel dimensions. Set the final dimensions after you finish framing. With Keep the crop area's aspect ratio on, changing one output dimension adjusts the other proportionally.

If you turn that option off, you can set the width and height separately. When their ratio differs from the crop, the image is stretched. Use this only when the destination requires those exact dimensions and you have checked how the subject looks.

The crop and output dimensions are each limited to 12,000 pixels on either edge and 12 megapixels in total. Enlarging is allowed within those bounds, but it cannot add detail that the source does not contain.

Check the format and open the downloaded copy

Choose PNG if the image needs transparent areas. JPG fills transparent areas with white and re-encodes the image, which may change its appearance slightly. Neither option preserves the original file byte for byte.

The preview helps you inspect the selected area and output dimensions. Open the downloaded file at the size where it will be used, especially when it contains small text, thin lines, or details near the crop edge.

Input limits

Choose one still JPG, PNG, or WebP image at a time. Animated images are not supported. The input limit is 10 MiB, 12 megapixels, and 12,000 pixels on either edge. Output dimensions are limited to 12 megapixels and 12,000 pixels per edge.
