How to use

  1. 1.Click Browse and choose the image you want to crop — it loads instantly and stays on your device.
  2. 2.Drag the selection box to frame the area you want to keep, resize it from the corner handles, or pick a 1:1, 4:3, 16:9, or 3:2 aspect-ratio preset to lock the proportion.
  3. 3.Click Crop image to cut out that region and download it as a lossless PNG.

About Image Cropper

Image Cropper trims a photo down to the exact region you want, entirely inside your browser. Load an image, drag the selection box over the part you want to keep, and click Crop — the tool copies that rectangle pixel for pixel into a new PNG and hands you a download link. Nothing is uploaded: the file is read locally, drawn to a canvas, and the cropped result never leaves your device.

Cropping here is a lossless cut, not a re-render. The tool maps your on-screen selection back to the original image's true pixel coordinates and uses a single drawImage call to copy that sub-rectangle at 1:1 scale. Because there is no scaling or resampling, every pixel inside the region you keep is byte-for-byte identical to the source — a crop only removes the pixels outside the box, it never repaints the ones inside. That is why the output is PNG by default: PNG is lossless, so the saved crop preserves sharp edges, text, and fine detail exactly.

Aspect-ratio presets make common jobs one click. Free lets you draw any rectangle. 1:1 gives a perfect square for profile pictures and avatars, where platforms often mask the image to a circle. 16:9 matches video thumbnails, YouTube covers, and slide decks. 4:3 suits classic camera frames and older displays. 3:2 is the native ratio of most DSLR and mirrorless cameras, ideal when you want a photographic crop that still feels like the original frame. When a ratio is locked, the corner handles resize the box while holding that exact proportion, so the result lands on the pixel ratio you asked for, and the live readout shows the output dimensions as you drag.

Everything runs client-side for a simple reason: privacy and speed. Screenshots, ID photos, receipts, and personal pictures never touch a server, so there is no upload wait, no queue, and no copy of your image sitting in someone else's storage. The interaction is immediate — drag inside the box to move it, drag a handle to resize, and watch the pixel dimensions update in real time.

A crop does not change the picture quality of what remains. Resolution, color, and compression of the kept area are untouched; the image simply has a smaller frame around fewer pixels. If you also need the result at a specific size or a smaller file, crop first, then run the output through the Image Resizer or Image Compressor. To turn the cropped PNG into a smaller photo-friendly JPEG, use PNG to JPG. The cropper focuses on one job — an accurate, honest cut — and does it without ever sending your photo anywhere.

Frequently asked questions

Does cropping reduce image quality?
No. Cropping is a pixel-perfect cut, not a re-render. The tool copies the selected region at 1:1 scale with no scaling or resampling, so every pixel you keep is byte-for-byte identical to the original. It only removes the pixels outside your selection.
What aspect ratio should I use?
Use 1:1 for square profile pictures and avatars, 16:9 for video thumbnails, YouTube covers, and slides, 4:3 for classic camera frames and older screens, and 3:2 for a natural DSLR/mirrorless photo crop. Choose Free to draw any rectangle you like.
Can I crop several images at once?
This tool crops one image at a time so you can frame each selection precisely. To crop another image, just choose a new file — the previous selection resets so you can start fresh.
Are my images uploaded to a server?
No. The entire crop runs in your browser using the Canvas API. Your image is read locally and never uploaded, which means there is no wait, no queue, and no copy of your photo stored anywhere.
What file format is the cropped image?
The cropped image is saved as a lossless PNG so no quality is lost in the cut. If you need a smaller, photo-friendly file afterward, run the result through PNG to JPG or the Image Compressor.
