Crop image

Upload an image, then drag the box to frame the part you want and drag a corner to resize. Lock a ratio like 1:1 or 16:9, or crop freely. Everything happens in your browser — your image is never uploaded.

How to crop an image

  1. Add your image above (drag in or tap to browse). It's read straight into your browser — nothing is ever uploaded.
  2. Drag the highlighted box to frame the part you want, and drag any corner to resize. Lock a ratio like 1:1, 4:3 or 16:9, or choose Free to crop to any shape.
  3. Click Crop and download the result. Only the area outside the box is trimmed away, so the pixels you keep stay sharp.

About cropping images

Cropping trims a photo down to the part that matters — removing empty edges, straightening a composition, or shaping an image for a profile picture, thumbnail or banner. Because it only discards the pixels outside the box, the area you keep is untouched: JPEGs are re-saved at high quality, while PNG and WebP stay lossless. Preset ratios (1:1, 4:3, 3:2, 16:9 and their portrait variants) keep a fixed shape as you resize, or Free lets you crop to anything.

Everything runs in your browser using the canvas, so your image never touches a server and nothing is stored online. That makes it safe for cropping ID photos, document scans, screenshots or anything private — there's no upload, queue or sign-up, and the result downloads straight back to your device.

Frequently asked questions

How do I crop an image?

Add your image, then drag the highlighted box to move it and drag any corner to resize. Pick an aspect ratio if you need a fixed shape, then click Crop to download the result.

Will cropping reduce the quality?

No. Cropping only trims away the area outside the box — the pixels you keep are untouched. JPEGs are re-saved at high quality; PNG and WebP stay lossless.

Can I crop to a square or 16:9?

Yes. Choose a preset ratio (1:1, 4:3, 3:2, 16:9 and portrait variants) and the box keeps that shape as you resize. Choose "Free" to crop to any shape.

Is my image uploaded anywhere?

No. The crop is done entirely in your browser — nothing is sent to a server or stored.
