How to crop an image online

  1. Add your image

    Drop a JPEG, PNG, or WebP onto the tool, click to browse, or paste one from your clipboard.

  2. Frame the crop

    Drag the box to position it and pull any corner handle to resize it, or type an exact width, height, and X and Y offset into the fields. The selection is measured in real pixels either way.

  3. Lock a ratio if you need one

    Choose 1:1, 4:3, 16:9, 3:2, or 9:16 to keep the box fixed to a shape, or stay on Free to crop to any proportions.

  4. Download the crop

    Click Download to save just the selected area, in the same format as the original, with -cropped added to the filename.

Why use this tool

Five fixed ratios plus free crop

1:1 for avatars, 4:3 and 3:2 for photos, 16:9 for widescreen, and 9:16 for vertical formats. Free mode drags without any constraint.

Type exact pixel dimensions

Width, height, and X and Y offset fields stay in sync with the box, so you can drag roughly then type the precise numbers a form or spec demands.

Rule-of-thirds grid

A toggle lays a three-by-three grid over the selection to help line a subject up along the classic thirds guides before you export.

Mouse and touch

The crop box is driven by pointer events, so it moves and resizes with a finger on a phone as readily as with a cursor.

Same format out as in

A cropped JPEG stays a JPEG and a PNG stays a PNG; only the pixels outside the box are discarded.

Private by construction

The crop is cut with the Canvas API on your own machine. No upload, no account, no watermark.

About this tool

This image cropper lays a draggable crop box over your photo and tracks the selection in the image's natural pixels, so what the fields say is what the exported file measures. Move the box, pull its corner handles, type an exact width, height, and X and Y offset, or pick a preset to snap it to a fixed aspect ratio; downloading renders only the selected region through the Canvas API and saves it in the original format. Selections larger than the browser's canvas ceiling of 8192 pixels per side are scaled to fit so the export cannot silently fail.

Common jobs include squaring a photo for an avatar, cutting a 16:9 frame out of a screenshot for a slide, trimming dead space from the edge of a scan, and framing a 9:16 slice for a phone wallpaper or story. Because the measurement is in pixels rather than a vague percentage, it also suits forms and platforms that demand an exact region.

Nothing you drop in is transmitted; the whole crop happens on your device. If you need to work out what dimensions a given ratio implies, the aspect ratio calculator does the arithmetic. To scale the cropped file to a target size afterwards use the image resizer, and to cut its file weight down use the image compressor.

Frequently asked questions

How do I crop an image?
Drop in a photo, then drag the crop box to move it and drag the corners to resize, or type an exact width, height, and position into the fields. Pick an aspect ratio to keep the crop locked to a shape. Download saves just the cropped area.
Can I crop to a square or a specific ratio?
Yes. Choose 1:1 for a square, or 4:3, 16:9, 3:2, and 9:16 for common photo and video shapes. Choose Free to crop to any size.
Are my images uploaded anywhere?
No. Cropping happens entirely in your browser using the Canvas API. Your image never leaves your device and is never sent to a server.
What formats are supported?
JPEG, PNG, and WebP. The cropped image keeps the same format as the one you dropped in.
