Image Cropper

Crop to a fixed ratio or freehand, taken from the full-resolution original rather than from the preview on your screen.

Runs in your browser — nothing is uploaded

Your image

Fixing a ratio keeps the shape while you drag the corner.

Your file never leaves this device. The whole operation runs in your browser — nothing is uploaded, queued on a server, or deleted later, because nothing was ever sent.

Cropped from the original pixels, not the preview

The selection is stored as a proportion, so the crop is taken from the full-resolution image no matter how small the preview is on your screen. A tool that crops what it displays quietly throws away resolution.

Why use it

Built to be genuinely useful

Cropped from the original pixels

The selection is stored as a proportion, so a small preview never costs you resolution.

Ratios that hold while you drag

1:1, 4:3, 16:9 and 9:16 stay locked, so a profile picture or a story frame comes out right first time.

Exact pixel readout

The crop size and position in real pixels, updating as you drag.

Nothing is uploaded

The whole crop happens in your browser — the photo never reaches a server.

How it works

Three steps

  1. 1

    Choose an image and, if you need one, a fixed aspect ratio.

  2. 2

    Drag the box to move it, or the corner handle to resize.

  3. 3

    Download as JPG or PNG.

Why cropping from the preview loses quality

A 6000-pixel-wide photo displayed in a browser is shown at perhaps 700 pixels. A tool that crops what it displays is working from that smaller copy, and the result is a fraction of the resolution you started with — usually noticed later, when the image is printed or opened full screen.

Storing the selection as a proportion of the image rather than as screen coordinates avoids that entirely. The crop is applied to the original at full size, so a quarter of a 6000-pixel image is 1500 pixels wide regardless of how the preview was scaled.

The pixel readout is there so you can check before downloading. If a platform needs 1080 by 1080 and your crop reads 840, you know before you upload rather than after it is rejected.

Which ratio to use where

Square, 1:1, is the safe default for profile pictures across almost every platform, and it is what LinkedIn, WhatsApp and most forums expect. A portrait crop shown in a circle loses the top and bottom of the frame, which is how people end up with their forehead cut off.

9:16 is the full-screen phone shape used by Instagram stories, reels and YouTube shorts. 16:9 is its opposite and the standard for video thumbnails and slide decks. 4:3 and 3:4 are the classic photographic shapes and what most print sizes are closest to.

PNG is worth choosing over JPG when the image contains text, screenshots or flat colour, because JPEG compression puts visible artefacts around hard edges. For photographs, JPG at high quality is smaller and indistinguishable.
