Crop Image
Free online image cropper. Custom size and preset ratios. Social media presets included. No download required, process locally for privacy. Crop profile pictures, cover photos instantly.
The image cropping tool retains specific parts of an image by selecting an area, removing unwanted edge regions. Cropping is one of the most commonly used image editing operations, capable of both removing excess edges to highlight the subject and adjusting image proportions for different scenarios. The tool supports two modes: free cropping and fixed ratio cropping. Free cropping allows dragging the crop box to select any area, while fixed ratio cropping locks the aspect ratio using presets such as 1:1, 4:3, 16:9, ensuring the cropped result meets specific platform or usage requirements.
Typical use cases include removing white borders and excess edges from images, cropping images to social media platform required proportions, recomposing to highlight subjects, and removing sensitive information areas from screenshots. For social media scenarios, different platforms have different image proportion requirements, such as Instagram square 1:1, YouTube cover 16:9, TikTok cover, etc. Fixed ratio cropping can quickly generate images that meet requirements. For composition adjustment scenarios, cropping can change the visual focus, making the image more focused on the subject.
All processing is done locally in your browser. Images are never uploaded to any server. Personal photos, design drafts, and other sensitive images remain on your device throughout the cropping process. Cropped images are downloaded directly to your local device without going through any intermediate servers, ensuring privacy and security.

Core Features
Free Cropping
Drag the crop box to select any area of the image for cropping without ratio restrictions. Suitable for scenarios requiring flexible area selection such as removing white borders, capturing local details, and removing sensitive information. The crop box can be freely adjusted in size and position for precise control of retained content.
Fixed Ratio Cropping
Provides common ratio presets such as 1:1, 4:3, 16:9, 3:2, locking the aspect ratio for cropping. Suitable for scenarios requiring specific platform requirements such as social media images, video covers, and presentation documents. Fixed ratio ensures cropped results won't be distorted and directly meet usage requirements.
Custom Size Input
Directly enter precise pixel dimensions and position coordinates of the crop area for pixel-level precise cropping. Suitable for scenarios requiring strict control of output size such as making icons, banners, or printed materials of specific sizes. Numerical input is more precise than dragging, avoiding errors.
Batch Cropping
Upload multiple images at once and crop them in batch. Download individually or package as a ZIP file for one-click download. Batch processing is suitable for scenarios requiring cropping of large numbers of images, such as unified processing of product images, batch generation of social media images, or organizing photo libraries.
| Ratio | Description | Typical Use |
|---|---|---|
| 1:1 | Square | Avatars, social media |
| 4:3 | Standard ratio | Presentations |
| 16:9 | Widescreen | Video covers |
| 3:2 | Photo ratio | Photography |
| Free | Any ratio | Remove white borders |
Use Cases
Remove White Borders
Crop away excess edge areas of images. Screenshots, scanned documents, and design drafts often have unwanted white borders or frames. Cropping can remove these excess parts, making the image content more compact. Free cropping mode is suitable for handling irregular edges, precisely removing excess areas.
Social Media Images
Crop images according to platform required proportions. Different social media platforms have different image proportion requirements, such as Instagram square 1:1, YouTube cover 16:9, Weibo cover, etc. Fixed ratio cropping can quickly generate images that meet each platform's requirements, avoiding forced cropping distortion after upload.
Composition Adjustment
Recompose to highlight the subject. Through cropping, you can change the visual focus of the image, move the subject to a more suitable position, and remove distracting background elements. Composition principles such as rule of thirds and golden ratio can all be achieved through cropping, making photos and design drafts more visually impactful.
FAQ
Can I crop to a specific ratio?
Yes. The tool provides common ratio presets such as 1:1, 4:3, 16:9, 3:2. After selection, the crop box will automatically lock the aspect ratio. You can also custom input any ratio value. Fixed ratio cropping is suitable for scenarios requiring specific platform requirements such as social media images and video covers, ensuring cropped results won't be distorted.
Will cropping reduce image quality?
No. Cropping only selects a local area of the image without resampling or compressing pixel data. The cropped image quality is exactly the same as the original. The resolution of the cropped image will be smaller (because edge areas are removed), but the clarity of the retained parts remains unchanged. If you need to change the size at the same time, it is recommended to use the resize tool after cropping.
Can I customize the crop size?
Yes. Besides dragging the crop box to select an area, you can directly enter precise pixel dimensions and position coordinates of the crop area. Numerical input is more precise than dragging, suitable for scenarios requiring strict control of output size such as making icons, banners, or printed materials of specific sizes, avoiding errors from manual dragging.
Can I crop images in batch?
Yes. Supports uploading multiple images at once and batch cropping. You can download individually or package as a ZIP file for one-click download. Batch processing is suitable for scenarios requiring cropping of large numbers of images, such as unified processing of product images, batch generation of social media images, or organizing photo libraries, significantly improving processing efficiency.
Can cropping be undone?
Before the cropping operation is completed, you can undo and readjust the crop box. But once you confirm the crop and download the result, the cropped edge areas are permanently lost and cannot be recovered from the cropped image. It is recommended to carefully preview the effect before confirming the crop, or keep a backup of the original image. If you are not satisfied with the cropping result, you can re-upload the original image and crop again.
Which image formats are supported?
Supports cropping of JPG, PNG, WebP and other mainstream image formats. Cropped images can be output in the original format or converted to other formats. PNG is suitable for graphics and screenshots requiring transparent backgrounds, JPG is suitable for photo-type images, and WebP combines the advantages of both as the preferred choice for modern web. Choose the most suitable output format based on image content.
