How to Use
- 1Open an image by clicking the drop area, dragging a file onto it, or pasting from clipboard (Ctrl+V).
- 2The crop overlay appears automatically on the full image. Drag the corner or edge handles to adjust the selection area.
- 3Drag inside the crop box to reposition the selection to frame the content you want to keep.
- 4Optionally enter exact width and height values in the sidebar for pixel-precise cropping.
- 5Select output format (JPEG, PNG, WebP) and adjust quality if needed.
- 6Click Save to save the cropped image; the result is ready instantly.
- 7How to crop a photo to a specific aspect ratio: open your image, enable Lock Aspect Ratio, enter your desired ratio (e.g., 16:9 for widescreen, 1:1 for social media profiles). Drag the corner handles to resize the crop area while the ratio stays fixed.
- 8How to crop a face or subject from a group photo: open the group photo, drag the crop box to frame the desired face or subject. Use the corner handles to adjust the selection precisely. Save as PNG to preserve quality for further editing.
Frequently Asked Questions
Does cropping change the pixel dimensions of my image?
Yes. Cropping removes the area outside your selection, so the output image size equals your crop region's pixel dimensions. The image is not scaled; only the canvas is trimmed to your selection.
Is there a maximum image size I can crop?
Since all processing happens in your browser, the limit depends on your device's available memory. Most images under 50MB work fine. Very large images (100MB+) may cause performance issues on lower-end devices.
Does cropping reduce image quality?
No. Cropping does not re-encode or compress the selected area; the crop region keeps its original quality. If you choose JPEG or WebP output, the quality setting only affects the final export, not the crop itself.
Can I crop to a specific pixel size?
Yes. Enter exact width and height values in the sidebar under the Dimensions section. The crop box adjusts to match your input, staying centered. Enable Lock Aspect Ratio to keep proportions when changing one dimension.
What image formats are supported?
The tool accepts JPG/JPEG, PNG, WebP, AVIF, BMP, GIF, and SVG as input (any format the browser can render). Output can be saved as JPEG, PNG, or WebP. PNG is recommended when you need lossless quality.
Why can't I crop an image into a circle?
No, this tool produces rectangular crops only. For a circle, crop to a square here first, then apply border-radius: 50% in CSS for the web, or use a dedicated circle-crop tool that exports a transparent-background PNG. A rectangular source keeps its corners in every output here.
Can I crop in centimeters (cm)?
No. Centimeters are a physical unit that depends on print DPI, so the tool works in pixels. To crop for print, convert first: at 300 DPI, 5 cm is about 591 pixels; at 150 DPI, about 295. Enter the pixel values in the Dimensions fields and lock the aspect ratio.
Can I undo a crop after saving?
Once the image is cropped and saved, the removed areas are permanently discarded. To preserve the original, keep a backup before cropping. The Reset button restores the full selection before you save.
Can I crop multiple images at once?
No. This tool processes one image at a time. For batch cropping, you would need to process each image individually. Each crop selection is specific to the image content, so manual per-image cropping ensures the best results.
How do I crop an image to a perfect square?
Enable Lock Aspect Ratio and set both width and height to the same value, or enter a 1:1 ratio. The crop box will maintain a perfect square as you resize it. This is useful for profile pictures, thumbnails, and Instagram posts.
Why does my cropped image look blurry or no bigger than the original?
Cropping removes pixels; it does not enlarge or upscale anything, so the output contains exactly the pixels inside your selection. If you need a larger image, use an image resizer after cropping, or start from a higher-resolution original. To keep maximum sharpness, export as PNG instead of JPEG.
Why do my pixel values change when Lock Aspect Ratio is on?
The ratio constrains both dimensions: entering a width computes the height from the ratio (and vice versa), and values are recalculated to the nearest matching pixel; with 16:9 and width 1000, the height is 1000/16x9 = 562.5, rounded to 563. The ratio takes priority over your exact numbers. If you need exact pixels, turn Lock Aspect Ratio off and enter both values separately.
Why doesn't this free image cropper online resize the image after cropping?
Cropping trims pixels; it never scales. If you want a specific final size, crop to the right composition and aspect first, then open the result in the Image Resizer for exact dimensions. Doing both in one step would either distort the image or degrade quality, so the two operations stay separate.
