Image Cropper with Aspect Presets
Drag-to-crop interface with handles for resize on every edge and corner. Aspect-ratio presets for Instagram (1:1, 9:16), YouTube (16:9), photography (3:2, 2:3), and standard (4:3, 3:4). Free mode for any rectangle. Runs entirely in your browser using the Canvas API; the image never leaves your device.

About cropping
Why crop?
Cropping removes parts of an image you do not want, focuses attention on the subject, or fits an image to a required aspect ratio. Almost every social media platform has a specific aspect ratio for posts: Instagram squares are 1:1, Stories are 9:16, YouTube thumbnails are 16:9, X post images are 16:9. Posting an image without cropping risks awkward auto-cropping by the platform.
Aspect ratios explained
An aspect ratio is the ratio of width to height. 16:9 means the image is 16 units wide for every 9 units tall, the standard widescreen format. 1:1 is square. 4:3 was the standard TV and computer monitor ratio until the mid-2000s; it is still used for some photos and Instagram's original square crop. 3:2 is the classic 35mm film and most DSLR ratio.
Social media crop targets
Instagram feed: 1:1 square (1080x1080) or 4:5 portrait (1080x1350). Instagram Story / Reels: 9:16 (1080x1920). Facebook cover: 16:9 aspect (820x312 with safe zones). LinkedIn banner: 4:1 aspect (1584x396). YouTube thumbnail: 16:9 (1280x720). X/Twitter post image: 16:9 (1200x675 or 1600x900). The cropper handles all of these.
Crop composition rules
The rule of thirds suggests placing key subjects on one-third lines rather than dead center for more dynamic composition. Headroom (space above the subject's head) should be minimal in portraits. For groups, leave a small margin around all faces. For products, center on a clean background with consistent margins. The cropper's overlay shows where the crop will land.
Lossless cropping
Cropping is lossless in the sense that the kept pixels are exact copies of the source. The cropper outputs PNG, which preserves every pixel. The original file (which you still have on your device) is unchanged unless you choose to replace it.
EXIF metadata
The Canvas API does not preserve EXIF metadata, so the cropped PNG has no location, camera, or timestamp data. This is a privacy benefit for public sharing but can be a loss for archival use. If you need EXIF preserved, use a desktop tool like ExifTool to copy metadata from the original to the cropped file.
Cropping for ML and AI use
Machine learning models often require fixed-size square inputs (224x224, 256x256, or 1024x1024 for newer models). The cropper's 1:1 preset gives a square crop; then use our image resizer to scale to the exact pixel size. This pipeline is much faster than running images through a desktop editor for batch ML preprocessing.
Working with very large images
Modern phone cameras produce 12 to 50 megapixel files. The cropper handles these in modern desktop browsers without issue. On mobile, very large files may cause slow drag response; resize first with our image resizer (e.g., to 4000 pixels wide) before cropping if you notice lag.
Privacy
The cropper runs fully in your browser. Network developer tools will confirm zero uploads. EXIF metadata strips automatically, which is good for sharing publicly. Original files on your device are not modified; only the downloaded cropped result is new.
Drop an image, drag the corner handles to define the crop area, and the tool renders the cropped result instantly using the browser Canvas API. Everything runs in your browser; the image never leaves your device. Download the result as a PNG.
Free (any ratio), 1:1 (Instagram square), 4:3, 3:4, 16:9 (YouTube thumbnails), 9:16 (Instagram Story), 3:2 (DSLR standard), and 2:3 (portrait). Click any preset to constrain the crop to that ratio. Switch to "Free" to drag any rectangle.
Yes. Instagram square is 1:1, YouTube thumbnail is 16:9, Instagram Story is 9:16, X/Twitter post images are 16:9. Pick the matching aspect ratio and drag the crop to your desired position. For exact pixel dimensions, use the cropper to define the area, then run the result through our image resizer.
Yes. The cropper extracts the chosen rectangle pixel-for-pixel from the source. There is no resampling or quality loss for the area you keep; only the discarded outside pixels are removed. The output PNG is lossless.
PNG. PNG was chosen because it is lossless and supports transparency. For smaller file size (at some quality cost), pass the cropped output through our image compressor with JPEG output and your preferred quality level.
Not with this tool. The cropper produces rectangular crops only. For circular or oval crops (profile pictures), you can crop to a square first, then use a tool that masks the corners. CSS can also display a square image as a circle without modifying the file.
The crop must stay within the image boundaries. Drag handles outside the original image are clamped. The minimum crop is 5 percent of the image in each dimension to prevent degenerate output.
Yes. Drag inside the crop area to reposition it. Drag any handle (corners or edges) to resize. If an aspect ratio is locked, the size adjusts to maintain that ratio.
No, this tool focuses on rectangular crops. For rotation, flip, or both, use our image rotator. Combining: rotate first, then crop, or vice versa depending on your workflow.
In theory, anything your browser can load. In practice, very large images (above 30 megapixels) may slow the interactive UI. For very large source images, downsize using our image resizer first, then crop the smaller version.
Yes. The Canvas API does not preserve EXIF data, so the cropped output has no EXIF metadata (location, camera info, etc.). This is a privacy feature for most users.
This cropper handles one image at a time because the crop area is usually image-specific. For batch crops of identically sized images (e.g., a series of product photos), command-line tools like ImageMagick are faster. For one-off crops of different images, this tool is the right choice.
Yes. The image stays in your browser. Nothing is uploaded, no server processing happens, and we keep no log. The browser developer tools network tab will confirm no upload happens.
