How it works

Three steps. Done in your browser.

Drop your image

Drag any JPEG, PNG, or WebP onto the crop zone, or click to browse from your device. No file size limit.

Select your crop area

Drag handles to define your selection. Pick a preset ratio like 1:1, 16:9, or 4:3, or crop freely to any dimensions.

Save the cropped image

Click Crop and save your result instantly. Same format, full quality, no upload required.

Use cases

When to crop an image.

Cropping removes unwanted areas, reframes composition, and adjusts aspect ratio without scaling or degrading the retained pixels.

Social media profile pictures

Instagram, LinkedIn, and most platforms display profile photos as squares. Cropping to 1:1 before upload ensures the important part is centred, not auto-cropped by the platform.

YouTube thumbnails

Thumbnails must be 16:9 ratio (1280x720 recommended). Cropping to the exact ratio before uploading prevents automatic cuts that could remove your subject from view.

Product photography

Platforms like Amazon and Shopify require images with specific aspect ratios. Cropping to a square with the product centred gives you full control over the final display.

Removing distracting backgrounds

Photos of documents, whiteboards, or artwork often include unwanted surroundings. Cropping removes the distraction and focuses attention on the content that matters.

Passport and ID photos

Government and visa applications specify exact crop ratios, often 35mm x 45mm with the face centred. Cropping to spec before printing avoids rejection at the counter.

Blog and CMS featured images

Most CMS platforms display featured images at a fixed aspect ratio. Cropping before upload prevents the platform from making poor automatic crops of your carefully framed shots.

How cropping works under the hood.

When you drag a crop selection, the tool tracks the bounding rectangle you define in pixel coordinates relative to the original image. On click, it uses the browser's Canvas API to draw only the selected region onto a new canvas at the original resolution, then exports it as a Blob URL for saving.

No pixels are scaled or resampled during this process. The retained area comes out at exactly the same resolution as the source, and no data ever leaves your device.

Common questions

Questions answered.

Can I crop to an exact pixel size?
Yes. Use the free crop mode and drag the handles to your desired area. The pixel dimensions of your crop selection are shown in real time so you can hit an exact size.
What aspect ratios are available?
You can crop freely (no ratio lock), or choose from presets: 1:1 (square, for Instagram posts), 4:3, 16:9 (landscape video), 9:16 (portrait/Stories), and others.
Does cropping reduce image quality?
Cropping itself does not degrade quality. It simply removes the pixels outside the selection. The retained pixels are exported at full quality.
Can I crop to a custom aspect ratio?
Yes. Use free crop mode and drag to any proportions you need. The tool shows the current pixel dimensions and aspect ratio in real time as you drag.
What happens to the file size after cropping?
File size decreases roughly in proportion to the area removed. Cropping 50% of an image typically reduces file size by 40 to 60 percent, depending on the content of the removed region.
Does cropping affect EXIF metadata?
The cropped output is a fresh canvas export, so most EXIF metadata (GPS coordinates, camera settings) is stripped. Only basic properties like dimensions are retained in the output file.
Can I undo a crop?
Re-upload the original image and crop again. The tool never modifies your original file. It only creates a new cropped version when you save.
Is my image uploaded to a server?
No. All cropping happens in your browser using the Canvas API. Your file never leaves your device.
