Image Cropper

Image Tools · Added

Choose which part of a picture to keep, either by dragging the box or by typing exact pixel coordinates. Aspect presets cover the shapes most uploads demand — square for a profile photo, 16:9 for a video thumbnail, 9:16 for a phone screen. The file is read straight from your device and never uploaded.

Or drop a file onto this box.

JPG, PNG, WebP, GIF, BMP or AVIF, up to 30.00 MB. It is read from your device and never uploaded.

PNG is lossless, so quality does not apply to it.

How to use the image cropper

  1. 1Choose an image, or drop it onto the box.
  2. 2Pick an aspect ratio, or leave it on Free to crop to any shape.
  3. 3Drag inside the box to move it, or drag a corner to resize. The four number fields do the same thing precisely and work without a mouse.
  4. 4Pick an output format. Keeping the original is usually right; JPEG will ask for a background colour because it cannot store transparency.
  5. 5Check the preview and the reported dimensions, then download.

Examples

A square profile picture from a landscape photo

Input
4000×3000 JPEG · aspect 1:1
Result
3000×3000, centred by default

The square is as large as the shorter side allows. Drag it left or right to frame the subject — the size stays locked while the position moves.

A 16:9 thumbnail from a phone photo

Input
3024×4032 portrait JPEG · aspect 16:9
Result
3024×1701

The width binds first on a portrait image, so the crop is a wide band. Most of the original height is discarded, which the area-kept figure reports as roughly 42%.

Trimming a screenshot to an exact region

Input
1920×1080 PNG · aspect Free · X 240, Y 130, width 800, height 450
Result
800×450 PNG

Typing coordinates is the reliable way to cut the same region out of several screenshots, and it is the path that works from the keyboard alone.

About the image cropper

Cropping is a framing decision, not a technical one

Every other transformation on this site has a correct answer you can check. A conversion factor is right or wrong; a compressed file is smaller or it is not. Cropping is the exception: the tool can guarantee that the region you selected is the region you get, and nothing beyond that. Which region is worth keeping is a judgement about the picture.

That is why the controls here are built around precision rather than suggestion. There is no automatic subject detection and no recommended crop, because a wrong guess about what matters in a photograph is worse than no guess at all. What the tool does provide is an exact box, a live preview of what survives, and a figure for how much of the original area you are discarding — which is usually the number that prompts a second look.

Why aspect ratios matter more than dimensions

Most places an image ends up care about its shape rather than its size. A profile picture is displayed in a circle inscribed in a square, so anything that is not square gets centre-cropped by the platform — often straight through the subject's head. A video thumbnail is 16:9. A phone-screen wallpaper is roughly 9:16. Getting the shape right locally means the platform never has to guess, and never crops somewhere you would not have.

The presets here lock the shape while leaving the position and scale free, which is the combination that matters: you can slide a locked 1:1 box across a group photo to pick a face without ever risking a rectangle that the platform will trim again. The portrait presets are listed separately from their landscape counterparts on purpose, because 9:16 and 16:9 are different shapes and choosing the wrong orientation is the most common mistake this list exists to prevent.

Dragging is the shortcut, typing is the control

A crop box you drag with a pointer is fast and obvious, and it is also the part of a tool like this that most often fails a keyboard or screen-reader user completely. The approach taken here is to treat the four numeric fields as the real interface — they are clamped to the image, they reflect every drag immediately, and every crop achievable by pointer is achievable by typing.

There is a practical benefit beyond accessibility. Typed coordinates repeat exactly, so cutting the identical region out of twenty screenshots is a matter of re-entering four numbers rather than trying to drag the same rectangle twenty times. Pointer dragging is genuinely better for framing a photograph, and typed values are genuinely better for anything systematic; keeping both in step means neither is a second-class path.

Frequently asked questions

Does the part I crop away leave my device?
No, and neither does the part you keep. The full image is decoded in the tab so the preview can show it to you, the region inside the box is copied onto a second canvas, and only that copy becomes the file you download. The area you discarded is never written anywhere at all — it exists in your browser's memory until you close the page, and then it is gone.
What is the difference between cropping and resizing?
Cropping changes which part of the picture you keep; resizing changes how many pixels describe the part you already have. Cutting a square profile photo out of a landscape shot is a crop. Making that square 400 pixels wide for an upload limit is a resize. The two are often done in sequence, and this site has a separate image resizer for the second step.
Does cropping reduce the image quality?
The pixels you keep are copied at their original resolution, so nothing is scaled or blurred. There is one indirect cost: if the output is JPEG or WebP, the file is re-encoded, and any lossy re-encode discards a little detail even at high quality. Choosing PNG output avoids that entirely, at the price of a larger file.
Why can I not edit the height when a ratio is selected?
Because the ratio determines it. With 16:9 chosen, the height is always the width divided by 16/9, so allowing both to be typed would let you enter a shape that contradicts the preset you picked. Switch the aspect to Free and both fields become editable.
Can I crop without using a mouse?
Yes. The four number fields — X, Y, width and height — are the full-fidelity control, not a secondary convenience. They are reachable by tab, accept typed values and arrow-key stepping, and are clamped to the image so an out-of-range value is corrected rather than rejected. The draggable box is a visual shortcut layered on top of them.
What happens to a transparent PNG?
Transparency survives if the output is PNG or WebP. JPEG has no alpha channel, so a background colour control appears when you select it and any transparent pixels are filled with that colour. Without the fill they would come out black.
