What Is an Image Cropper?

An image cropper lets you cut a rectangular section out of a larger image, discarding the rest. Cropping is one of the most common photo edits — used to remove distracting backgrounds, change composition, fit a profile picture into a square, or prepare a thumbnail. This tool crops JPG, PNG, and WebP images directly in your browser using the HTML Canvas API; the file never leaves your device.

Aspect Ratio Locking

Locking the aspect ratio keeps the crop box at a fixed shape no matter how you resize it. Use 1:1 for Instagram posts and profile photos, 16:9 for YouTube thumbnails and presentation slides, 9:16 for Instagram or TikTok stories, and 4:3 for classic photo prints. Leave it on Free when you want full control over both dimensions.

Lossless vs Lossy Output

PNG cropping is fully lossless — every pixel inside the crop box is preserved exactly. JPG output is re-encoded at high quality (92%), which is visually identical to the original for almost any photo. If you crop a JPG many times, save the result as PNG to avoid generation loss.

Privacy

This cropper runs entirely in your browser. There is no upload, no server processing, no tracking, and no account requirement. Close the tab and nothing is retained.

Frequently asked questions

Is the image uploaded?

No. The crop happens with Canvas in your browser. Your file never leaves your device.

Can I crop to exact pixel dimensions?

Yes — type custom width and height values into the inputs and the box updates instantly.

Does it keep transparency?

PNG input is exported as PNG (transparency preserved). JPG input exports as JPG.

What's the maximum image size?

Limited only by your browser's memory — typically 50–100 MB works fine on desktop.

Can I crop multiple images at once?

Not in batch — crop one image, download, then upload the next. Each crop takes a second.
