Crop Image

This image cropper cuts a PNG, JPG, WebP, GIF, BMP or AVIF image down to the rectangle (or circle) you choose, directly in your browser. It is for anyone who needs a profile picture, a product shot, a screenshot detail or a photo that fits a 1:1, 4:5 or 16:9 slot, and the image is never uploaded to a server.

You choose the area in two ways that stay in sync. Drag on the picture to draw a box, drag the box to move it, or drag one of its eight handles to resize it; on a phone the same works with a finger. Or type X, Y, Width and Height in pixels — the box on screen follows. The aspect presets (Free, 1:1, 4:3, 3:2, 16:9, 9:16 and 4:5) lock the shape: choosing one places the largest box of that shape in the centre, so 1:1 on a 4032 × 3024 phone photo gives 3024 × 3024 starting 504 px from the left. With a ratio locked, dragging a corner keeps the opposite corner fixed and typing a width sets the height. The box can never leave the picture, and every value is snapped to whole pixels. With the keyboard, Tab to the box and use the arrow keys to move it (Shift for 10 px steps) and Alt+arrows to resize it.

Circle crop draws the largest circle that fits the box (an ellipse if the box is not square) and makes everything outside it transparent. Because JPG cannot store transparency, a circle crop of a JPG is saved as PNG when "Save as" is "Same as input"; if you pick JPG explicitly, the corners are filled with the colour you choose. WebP keeps the transparent corners.

How it works: the browser decodes the image with its own codecs (phone photos are turned upright using their EXIF orientation, so the coordinates are those of the picture you see), then copies exactly the pixels inside the box onto a canvas of the same size — no resizing, so nothing is resampled — and encodes it. PNG output is lossless. JPG and WebP output is re-compressed at the quality you set (92 by default), which adds a small amount of compression loss. GIF, BMP and AVIF are saved as PNG for "Same as input", because browsers can read but not reliably write those formats, and an animated GIF keeps only its first frame. EXIF metadata such as camera model, date and GPS location is not copied into the output.

Limits: one image at a time, up to 50 MB, and the cropped result can be up to 16,384 px on a side and 100 megapixels. iPhones and iPads allow canvases of only about 16.7 megapixels, so cropping very large photos may fail there with a message saying so.

If you need the whole picture smaller rather than a part of it, use the image resizer; to make the file smaller without changing what it shows, use the image compressor.

Your image stays on your device. It is read into the page's memory, cropped there and offered back as a download; you can confirm in your browser's developer tools (Network tab) that no request carries your file.

1. The file's first bytes are checked to confirm it really is PNG, JPG, WebP, GIF, BMP or AVIF, and its size is checked against the 50 MB limit before it is read. 2. The browser decodes it with EXIF orientation applied, giving the upright width w and height h. 3. An aspect preset a (width ÷ height) places the largest centred box: width = w, height = w ÷ a; if that is taller than h, height = h and width = h × a. 4. Pointer positions are converted to image pixels as (pointer − picture edge) ÷ displayed size × image size, clamped to the picture. Moving keeps the size; resizing moves only the dragged edges, and with a ratio a corner drag keeps the opposite corner fixed and takes the larger of the two implied sizes, then shrinks to fit inside the image. 5. Each edge of the box is rounded to the nearest whole pixel, keeping the box at least 1 × 1 and inside the image. 6. Those pixels are copied 1:1 onto a canvas of the crop size (for a circle, clipped to the inscribed ellipse first) and encoded as PNG, JPG or WebP, named like photo-cropped.jpg.
