Image Cropper: Crop Photos to Any Size or Ratio
Crop a photo right in your browser. Upload an image, drag the crop box or pick a 1:1, 4:3, 16:9 or 9:16 shape, fine-tune with exact pixel values, then download or copy the result. Runs in your browser — images are never uploaded.
An image cropper is a tool that cuts a rectangular area out of a picture and discards the rest, so you can trim unwanted edges, reframe a subject or fit a required shape. This one runs in your browser: you choose the area by dragging a box, picking an aspect ratio or typing exact pixels, then download the result.
How to Use the Image Cropper
- Upload a picture. Drag it onto the upload area or tap to browse. The original size in pixels appears under the preview.
- Pick a shape. Choose Free, 1:1, 4:3, 16:9 or 9:16. A preset selects the largest centred area of that shape.
- Adjust the area. Drag the box to move it and drag its corner to resize it, or type X, Y, width and height for an exact crop.
- Press Crop. The result is shown with its size and file format.
- Download or Copy Image. Press Clear to start again with another picture.
Aspect Ratio Presets: 1:1, 4:3, 16:9 and 9:16
An aspect ratio is the width of a picture divided by its height. The table shows what each preset selects from a 4000 × 3000 pixel photo, which is what you get if you upload one and tap the button.
| Preset | Shape | Crop from a 4000 × 3000 photo | Typical use |
|---|---|---|---|
| Free | Any | 4000 × 3000 px (whole image) until you drag or type | Trimming edges, cutting out a detail |
| 1:1 | Square | 3000 × 3000 px (X 500, Y 0) | Profile pictures, avatars, square thumbnails |
| 4:3 | Landscape | 4000 × 3000 px (whole image) | Classic photo and slide shape |
| 16:9 | Widescreen | 4000 × 2250 px (X 0, Y 375) | Video frames and widescreen slides, such as 1920 × 1080 |
| 9:16 | Vertical | 1688 × 3000 px (X 1156, Y 0) | Full-screen vertical phone video, such as 1080 × 1920 |
With a preset active the shape stays locked: change the width and the height follows. Tap Free to unlock it.
How Image Cropping Works
Cropping removes unwanted portions from the edges of an image to keep a specific area. This tool uses the HTML5 Canvas API to copy a rectangular region of your original image, defined by the X and Y coordinates of its top-left corner plus a width and height. Nothing is scaled or resampled: each pixel you keep is copied one-to-one.
Because the whole operation runs locally in your browser with JavaScript and the Canvas API, your images are never transmitted to any server. That makes the tool suitable for personal photos, confidential business images and sensitive documents.
Crop Parameters
X: Horizontal offset from the left edge (pixels)
Y: Vertical offset from the top edge (pixels)
Width: Width of the crop region (pixels)
Height: Height of the crop region (pixels)
The crop area must fit within the original image dimensions. If the crop extends beyond the image boundaries, it will be clamped automatically.
Output Format and Quality
The cropped file is saved in the format your browser can write for that image:
| Your file | Saved as | What happens to quality |
|---|---|---|
| JPEG (.jpg) | JPEG | Encoded again at 95% quality |
| PNG | PNG | Lossless; transparency is kept |
| WebP | WebP, or PNG if the browser cannot write WebP | Encoded again at 95% quality |
| GIF, BMP and other formats | PNG | Lossless; an animated GIF becomes one still frame |
The result panel names the format before you download. Copy Image always places a PNG on the clipboard, because that is the image format browsers accept there.
When to Crop Images
Cropping is useful when you need to remove distracting elements from the edges of a photo, focus on a specific subject, or match the shape required for a profile picture, a video frame or a print layout. It is one of the most commonly used image editing operations and can noticeably improve the composition of a photograph.
Tips for Better Crops
Follow the rule of thirds by placing your subject off-center for more visually interesting compositions. When cropping portraits, avoid cutting at joints like elbows or knees. For product photos, leave some breathing room around the subject. Always preview your crop before downloading to ensure the result looks balanced and well-composed.
Privacy and Security
All image processing happens entirely in your browser. Your files are never uploaded to any server, making this tool safe for personal photos, confidential business graphics, and sensitive documents. You can verify this by monitoring your browser network tab during cropping.

Frequently Asked Questions
Is this image cropper free to use?
Yes. It is free, with no usage limits, watermarks or sign-up. The crop is done by your own browser, so there is nothing to pay for and no account to create.
Are my images uploaded to a server?
No. All cropping happens locally in your browser using the HTML5 Canvas API and JavaScript. Your images never leave your device, which makes the tool suitable for personal or confidential photos.
What image formats does this cropper support?
It opens any image format your browser can display, typically JPEG, PNG, WebP, GIF and BMP. JPEG, PNG and WebP crops are saved in the same format where the browser can write it. Other formats, including GIF and BMP, are saved as PNG, and an animated GIF is cropped as a single still frame.
How do I crop an image to exact pixel dimensions?
Upload the image, then type the left offset (X), top offset (Y), width and height in pixels. The box on the preview moves as you type, and the tool keeps the area inside the image. Press Crop to see the result with its exact size before you download it.
Is my data safe when using this tool?
Yes. This tool runs 100% in your browser using JavaScript. No image is sent to any server, stored in any database, or shared with any third party. When you close the page, processing stops immediately.
How do I crop an image to 1:1, 16:9 or 9:16?
Upload the image and tap an aspect ratio button. The tool selects the largest centred area of that shape, for example 3000 x 3000 pixels from a 4000 x 3000 photo for 1:1, or 4000 x 2250 for 16:9. Drag the box to choose a different part of the picture, or drag its corner to make it smaller while the shape stays locked.
Does cropping an image reduce its quality?
Cropping does not scale the picture, so every pixel you keep stays the same size. PNG crops are saved losslessly. JPEG and WebP are lossy formats, so the cropped area is encoded again at 95 percent quality, which is visually close to the original but not bit-identical.
