Image Cropper
Drag a selection, snap to a fixed ratio if you need one, and export the exact region you want — with live pixel coordinates throughout.
About the Image Cropper
Cropping is the most consequential edit most images ever get. It decides what the picture is about. A product shot with forty percent empty background reads as amateur; the same shot cropped tight reads as deliberate. A profile photo that includes shoulders and a doorway becomes a portrait when it is cropped to a square around the face. Nothing else you can do to an image in ten seconds changes it as much.
The practical problem is aspect ratios. Platforms are strict: a 1:1 square for most profile pictures, 16:9 for video thumbnails and hero banners, 4:5 for the tallest image Instagram will show in a feed, 1.91:1 for Open Graph link previews. Crop by eye and the platform will crop again on top of you, usually badly. Locking the ratio before you drag means the export is already correct.
This cropper draws your image on a canvas with a draggable, resizable selection box over it. Ratio presets lock the proportions, the live readout shows the exact pixel offset and size of the selection, and the export is a genuine pixel-accurate crop of the original resolution — not a scaled screenshot of the preview. The file never leaves your browser.
How to use it
- Load your imageDrag a file in or browse for one. It is drawn onto the canvas at a size that fits your screen while the full resolution is kept for export.
- Drag out a selectionClick and drag anywhere on the image to define the crop region, then drag the box itself to reposition it.
- Lock a ratio if you need oneChoose free-form, square, 4:3, 16:9, 3:2, 4:5 or 1.91:1 and the selection keeps those proportions as you resize.
- Fine-tune with the readoutLive X, Y, width and height values in original-image pixels let you match an exact specification.
- Preview the cropThe selected region is previewed at its true output size before you commit.
- ExportDownload as PNG for lossless output or JPEG when file size matters more.
Features
- Draggable selectionDraw, move and resize the crop box directly on the image with the mouse or by touch.
- Ratio presetsFree-form plus square, 4:3, 16:9, 3:2, 4:5 and 1.91:1 for social and video formats.
- Pixel-accurate readoutLive coordinates and dimensions in the original image's pixel space, not the preview's.
- Full resolution outputThe crop is taken from the original image data, so no resolution is lost to the on-screen preview.
- Quick actionsSelect all, centre the selection or reset in one click when you want to start over.
- Runs locallyThe image is never uploaded, which matters for ID photos, documents and anything personal.
Who uses this tool
- Profile picturesCrop a square around the face so LinkedIn, X or a company directory does not do it for you.
- YouTube creatorsCut a 16:9 region for a thumbnail with the subject positioned where it survives the platform's overlays.
- Online sellersTrim dead space out of product photos so the item fills the frame in a grid of search results.
- Document handlingCrop a scan or photograph of a form down to the page, removing the desk and hands around it.
Tips worth knowing
- Crop before resizing. Cropping first means the resize works only on the pixels you are keeping, which gives a sharper result.
- Leave a little breathing room above a head in a portrait — a crop that touches the hairline looks cramped at small sizes.
- For thumbnails, keep the important subject away from the bottom-right corner, where platforms overlay durations and badges.
Frequently asked questions
Does cropping reduce image quality?
No. Cropping removes pixels from the edges; the pixels you keep are unchanged. Exporting as PNG keeps them exactly as they were. Exporting as JPEG re-encodes them, which is a small, separate loss you control with the quality setting.
How do I crop to an exact pixel size?
Drag any selection, then read the live width and height display while you adjust the handles until they match your target. The readout is in original-image pixels, so what it says is what you get.
What aspect ratio should a profile picture be?
Square, 1:1. Almost every platform displays profile pictures in a circle or square, so anything else gets cropped automatically — usually through the top of the head.
Can I crop on a phone or tablet?
Yes. The selection box responds to touch, so you can drag and resize it with a finger. The ratio presets are especially useful on a small screen where precise dragging is harder.
Is my image uploaded when I crop it?
No. The file is read locally and drawn to a canvas in your browser. Nothing is transmitted, so cropping an ID document, a medical form or a private photo does not put it on anyone's server.
Can I undo a crop after exporting?
The exported file is a new image and does not contain the discarded pixels, so keep your original. The tool never modifies the source file on your device — reload it to start again from the full frame.
