Image Cropper
Crop by hand or snap to a ratio — square, circle, widescreen, or freeform. Everything runs in your browser — nothing is uploaded. Need to resize or convert instead? Resize or convert.
How to crop an image
Cropping keeps a rectangular (or circular) section of an image and discards the rest — unlike resizing, which scales the whole picture down or up. Use it to remove distracting edges, cut a photo to a specific ratio, or make a circular profile picture.
- Add your images, or drop them in.
- Pick a ratio — Freeform for full control, or a preset like Square or 16:9 — then drag the box or its corners into place.
- Click Apply Crop. The tool moves to the next image automatically; when you're done, download each file or grab them all as a ZIP.
Drag to the pixel
Move and resize the crop box freely, or lock it to a ratio so it can't be stretched out of shape.
Batch, one at a time
Add a whole folder. The tool queues every image and walks you through cropping each one in turn.
Nothing is uploaded
Cropping happens in your own browser using the Canvas API. Your photos never touch a server.
Other image tools
Cropping cuts pixels away. For the whole-image jobs, use one of these instead:
Can I undo a crop?
Not within this tool once you've downloaded the result — cropping permanently discards the pixels outside the box, unlike resizing, which can be reversed by starting again from the original file.
Click Re-crop on any row before you close the tab to adjust a crop you've already applied; it reopens the original image with your last crop box in place.
Choosing a crop ratio
The right ratio depends on where the image is going, not on what looks best in isolation. A profile picture almost always ends up masked to a circle by the platform showing it, so cropping to a square first — centred on the face — gives the platform's own circular mask nothing awkward to cut into. This tool's Circle preset shows that mask directly while you crop, so you see exactly what will be cut before you download.
16:9 is the shape of a video frame and most desktop screens, which makes it the right choice for YouTube thumbnails, video-call backgrounds, and header images that sit above a wide layout. 9:16 is the same ratio turned on its side — Stories, Reels, and anything meant to fill a phone screen top to bottom.
4:3 and 3:2 exist because that's what came out of the camera in the first place — 4:3 from most phones, 3:2 from most dedicated cameras. Cropping back to the source ratio after you've already zoomed or straightened an image keeps the framing honest rather than introducing a new distortion.
Freeform is for everything else: cutting a person out of a group photo, removing a border, or isolating one part of a screenshot. There's no ratio to protect there, so the box moves and resizes without any constraint.
Frequently asked questions
Why does the Circle option produce a square image with rounded corners?
Almost nothing actually stores a circular image file — formats work in rectangles. What the Circle preset does is crop a square and make everything outside the circle transparent, which is why the output is always a PNG regardless of what you uploaded. Any app that displays it in a circular frame (Instagram, Slack, Gmail) will show it as a clean circle; opened directly, you'll see the square canvas with transparent corners.
Does cropping reduce image quality?
No. The pixels you keep are copied exactly as they were — cropping doesn't resample or recompress anything on its own. The one exception is JPG output, which re-applies JPG's own lossy compression when the file is saved, the same as any JPG re-save.
Can I crop many images at once?
You can add many at once, and the tool queues them so you crop each one in turn — cropping is inherently a one-at-a-time decision, since every photo needs its own box position. Once you've cropped everything, download the results together as a ZIP.
Is there a limit on file size or how many files I can crop?
No. Cropping runs inside your browser rather than on a server, so there is no upload, no queue and no cap. Very large images may simply take a moment to load into the editor on a slower device.
Are my images uploaded anywhere?
No. Cropping happens entirely in your browser using the Canvas API. Nothing is transmitted, stored or logged, and you can disconnect from the internet after the page loads and it will still work.
