What this image cropper does
Cropping removes the parts of a picture you do not need and keeps the rest at full resolution. Load an image, then drag on it to draw a selection, pull the corner handles to adjust, or drag the box itself to reposition it. Preset buttons lock the shape to common ratios such as 1:1 for avatars, 4:5 for social feeds, 16:9 for video thumbnails and 9:16 for stories. If you prefer precision, type the exact X, Y, width and height in pixels. Keyboard users can focus the crop area and nudge it with the arrow keys, holding Shift for bigger steps and Ctrl to resize.
When to use it
- Creating square profile pictures from a portrait or landscape photo.
- Trimming a screenshot down to the relevant window or error message.
- Framing product photos consistently for an online shop.
- Cutting out black borders, scanner edges or distracting backgrounds.
Composition and quality tips
Crop to the final shape first, and resize afterwards. Because cropping simply selects existing pixels, the cropped area keeps the original sharpness; scaling it up later is what makes it blurry. A useful framing guide is the rule of thirds: the faint grid inside the crop box shows where to place eyes or a horizon so the image feels balanced. Leave a little breathing room around the subject when the picture will be cropped again by a website or social app.
Think about the platform ratio before you start. Most feeds crop automatically to a fixed shape, and doing it yourself lets you choose what is kept. For saving, PNG preserves every pixel, while JPG and WebP give smaller files for photos. Remember that JPG cannot store transparency, so use PNG or WebP if your picture has see-through areas. Very large photos are handled gracefully, but if your device is short on memory, crop in two steps.
Worked example: a square avatar from a landscape photo
Load photo.jpg, a 4000 × 3000 landscape picture, and press the 1:1 preset. The tool places the largest centred square that fits: 3000 × 3000 pixels starting at X 500 and Y 0, so 500 pixels are trimmed from each side. Drag the box left or right to choose what stays. Press 16:9 instead and you get 4000 × 2250 at X 0 and Y 375, which removes 375 pixels from the top and from the bottom. With the default PNG output, the square is saved as photo-cropped-3000x3000.png. The selected pixels are copied as they are, so the square is exactly as sharp as the original.
Privacy: cropping stays on your device
The cropper draws your picture on a canvas inside your browser and cuts the selected rectangle locally. The file is never uploaded, and the tool keeps working without a connection after the page has loaded. Photo orientation from your camera is applied automatically, and location metadata is not copied into the cropped file.
Frequently asked questions
How do I crop an image to a square?
Load your picture, press the 1:1 preset, then drag the box to the part you want. Press "Crop and download" to save the square.
Can I crop to an exact pixel size?
Yes. Type the width and height in the numeric fields. If a ratio preset is active, changing one value adjusts the other; choose Free to set them independently.
Does cropping reduce image quality?
No resampling takes place, so the selected pixels are copied unchanged. Quality is affected only if you save as JPG or WebP at a low quality setting.
Can I crop on a phone or tablet?
Yes. The crop box and handles respond to touch, and the handles are larger on touchscreens. The numeric fields are an alternative when you need fine control.
Is the original file changed?
No. Your original stays exactly as it was. The tool produces a new file when you press download.
