To crop an image, open a JPG, PNG or WebP above, then drag the crop box over the preview or pick a preset such as 1:1 or 16:9. For precision, type Width, Height, X and Y in pixels. Click Crop image to save the result in the same format, named with -cropped. The crop happens in your browser at the image's real resolution.
How to use the Crop Image tool
- 1
Open your image
Drop a JPG, PNG or WebP file onto the drop area or click to choose one, up to 50 MB. The image appears as a preview with a crop box on top.
- 2
Pick a ratio or go free
Choose Free, 1:1, 16:9, 4:3, 3:2 or 9:16. A preset locks the crop box to that shape while you move and resize it.
- 3
Position the crop
Drag the box to move it and drag its corners to resize. Use the arrow keys to nudge by 1 px, or Shift plus an arrow for 10 px, or type exact Width, Height, X and Y values.
- 4
Click Crop image
The selected area is cut out of the full-resolution image and offered as a download named after the original with -cropped added.
Crop a photo or picture to a common shape
Most cropping is about fitting a destination. A profile picture usually wants a square, a video thumbnail or presentation slide wants a wide frame, and a phone story or vertical video wants a tall one. The aspect presets cover the usual cases: 1:1, 16:9, 4:3, 3:2 and 9:16, plus Free when you just want to remove an edge.
To crop image to square, pick 1:1 and drag the box over the part of the photo that matters; the box keeps its square shape as you resize it from a corner. To crop image 16:9 for a widescreen thumbnail or banner, choose 16:9 and do the same. Switching to 9:16 gives the vertical version of that frame for stories and short-form video.
The same tool works whether you want to crop photo files from your camera, crop picture downloads you saved from the web, or trim the empty margins off a screenshot. Only one image is cropped at a time, because each crop is a visual decision.
Crop image to specific size or exact pixels
Dragging is fine for casual crops, but some jobs need precise numbers: an upload field that requires a certain width and height, a grid of images that must line up, or a screenshot region you want to reproduce exactly. The Width, Height, X and Y fields let you type those values directly. X and Y set the top-left corner of the crop, measured from the top-left corner of the image.
All values refer to the image's real pixels, not the size of the preview on your screen. A 4000 px wide photo shown in a small preview is still cropped in 4000 px coordinates, so a 1200 px wide crop really is 1200 px wide in the saved file.
For fine positioning, select the crop box and use the arrow keys: each press moves it by 1 px, and holding Shift moves it by 10 px. Cropping only cuts; if you then need the result at a smaller size, run it through the resize tool afterwards.
Can you crop image without losing quality?
Cropping removes pixels around the edges but does not scale what remains, so the area you keep stays at its original resolution. The result is saved in the same format as the input. PNG files are saved losslessly, so a cropped PNG is pixel-identical to that region of the original.
JPG and WebP files are re-encoded at quality 92 when saved. At that level the difference from the source is very hard to see, but it is not mathematically lossless, so keep the original if you might crop it again differently later.
The image is processed entirely inside your browser tab. It is not uploaded to Krawly's servers, nothing is stored, and there is no signup or watermark.
Tips for the best results
- Pick the aspect preset before positioning the box; it is quicker than adjusting width and height by hand.
- Use Shift plus the arrow keys to slide the crop in 10 px steps, then plain arrows for the last pixel or two.
- For an upload that needs both a ratio and a pixel size, crop to the ratio first, then resize to the exact dimensions.
- Leave a little space around faces and subjects; tight crops often look cramped once displayed in a rounded or circular frame.
- Keep your original file so you can re-crop it differently later without stacking JPG re-encodes.
Frequently asked questions
How do I crop an image online for free?
Open a JPG, PNG or WebP image on this page, drag the crop box or type exact pixel values, then click Crop image. The cropped file downloads straight away. There is no signup, no watermark and no daily limit, and the image never leaves your device.
How do I crop an image to a square?
Choose the 1:1 preset. The crop box becomes a square and stays square while you move it or drag its corners. Position it over the part of the picture you want to keep and click Crop image. This is the usual shape for profile pictures and product grids.
Can I crop an image to an exact pixel size?
Yes. Type the Width and Height of the crop in pixels and set X and Y for its top-left corner. The numbers refer to the image's real pixels, not the on-screen preview, so the saved file has exactly the dimensions you entered.
Does cropping reduce image quality?
The kept area is not scaled, so its resolution is unchanged. PNG crops are lossless. JPG and WebP crops are re-encoded at quality 92, which is visually very close to the original but not bit-for-bit identical. Keep the source file if you may need to crop again.
Which formats can I crop?
JPG, PNG and WebP, one image at a time, up to 50 MB. The cropped file keeps the input format, so a PNG stays a PNG with its transparency, and is named after the original with -cropped added before the extension.
Is my photo uploaded when I crop it?
No. Cropping runs in your browser using its built-in canvas. The image is read from your device into the tab's memory, cropped there and handed back as a download. Nothing is sent to Krawly's servers, and closing the tab discards everything.
Private by design. Every Krawly converter runs inside your browser using JavaScript and WebAssembly. Your files are not uploaded, stored or seen by anyone — when you close the tab, they are gone.
