Crop Image
Frame your photo with a draggable, resizable crop box and optional aspect-ratio presets. Free, private and processed entirely in your browser.
Cropping happens in your browser — your images are never uploaded.
How it works
When you load a photo it is drawn onto an HTML <canvas> scaled to fit
your screen, with a movable overlay marking the crop region. Dragging inside the box
repositions it; dragging a corner handle resizes it. When you click Crop
image, the tool converts your on-screen selection back into the image’s real
pixel coordinates and copies just that rectangle onto a fresh canvas at full resolution.
That canvas is then exported to a downloadable file. Because every step runs in
JavaScript on your own device, the picture is never uploaded to a server.
How to crop an image
- Click the box and choose a photo, or drag one in.
- Pick an aspect ratio preset, or leave it on Free.
- Drag inside the box to reposition, or drag a corner to resize the selection.
- Click Crop image to render the selection at full resolution.
- Download the cropped image.
Why crop in your browser
Cropping is the fastest way to fix composition: straighten a horizon by trimming, cut out distractions at the edges, or reframe a wide photo into a tight portrait. A fixed ratio matters when an image has to fit a slot exactly — a 1:1 square for an avatar or product thumbnail, 16:9 for a video poster or slide, 4:3 for many print sizes. Locking the ratio means the box keeps its shape while you choose how much to keep, so the result drops straight into the layout without leaving awkward bars or forcing a second resize.
Doing it locally keeps things private and instant. Many free croppers upload your file, process it on a server, and hand back a watermarked or size-limited result. Here the work happens in your browser tab, so there is no upload wait, no queue and no third party touching your image. Want to shrink the file afterwards, change dimensions, or convert the format? Pair this with the image compressor, the resizer, or the converter.

Frequently asked questions
How do I crop an image precisely?
Drop your image, then drag inside the crop box to move it or drag any corner handle to resize. The live selection size in pixels is shown beneath the preview, so you can frame the shot exactly before exporting.
Can I crop to a fixed aspect ratio like 1:1 or 16:9?
Yes. Pick a preset — Square (1:1), Widescreen (16:9) or Standard (4:3) — and the crop box locks to that shape so the height adjusts automatically as you resize the width. Choose Free to crop to any proportions.
Are my photos uploaded when I crop them?
No. Cropping is done entirely in your browser with the Canvas API. The pixels never leave your device and nothing is sent to a server, so even sensitive screenshots or documents stay private.
Does cropping reduce image quality?
No. Cropping only removes pixels outside your selection; the pixels you keep are copied at their original resolution. The output keeps the source format (JPEG, WebP or PNG), so there is no extra re-compression of the kept area beyond the format default.
What size will my cropped image be?
The export is measured in the original image’s real pixels, not the on-screen preview. If the preview is scaled down to fit your window, the tool maps your selection back to full resolution so you do not lose sharpness.
Which formats can I crop?
You can crop any image your browser can open, including JPG, PNG, WebP, GIF and BMP. JPEG and WebP sources are saved back in the same format; anything else is exported as PNG to preserve transparency and detail.
