Crop Image Online

Drag a crop box over your image, snap to an aspect ratio, and download. 100% in your browser — no upload, no sign-up.

Drop an image to crop

Drag & drop or click to choose — PNG, JPEG, or WebP

Quick Answer

Cropping an image online takes three steps: drop your PNG, JPEG, or WebP into the tool, drag the crop box (or snap to 1:1, 4:3, 16:9, 3:2, or 9:16), then download. Everything runs locally in your browser, so photos never leave your device. PNG transparency is preserved when you export as PNG, and the live pixel readout shows the exact output dimensions before you save.

How It Works

1

Drop in a PNG, JPEG, or WebP file — or click to browse

2

Drag the crop box to move it, or drag a corner to resize

3

Snap to 1:1, 4:3, 16:9, 3:2, or 9:16, or keep it free-form

4

Pick PNG to keep transparency, then crop & download

Key Facts

  • Drag the crop box to move it, drag any corner to resize it
  • Aspect presets: free, 1:1, 4:3, 16:9, 3:2, and 9:16
  • Live pixel readout shows crop width × height and position
  • Draw a fresh box by dragging anywhere outside the current one
  • Exports PNG (keeps transparency), JPEG, or WebP
  • Accepts PNG, JPEG, and WebP input at original resolution
  • 100% client-side — no upload, no sign-up, works offline

Frequently Asked Questions

Is my image uploaded when I crop it?

No. The cropper works entirely inside your browser using the canvas API. Your file is decoded locally, the crop is computed on your device, and the result is saved straight to your downloads. No server, no account, no telemetry — it even works offline once the page has loaded.

Can I crop a PNG and keep transparency?

Yes. Leave the export format on PNG and every transparent pixel stays transparent — PNG is lossless, so the cropped area is copied pixel-for-pixel. Avoid JPEG output for transparent images: JPEG has no alpha channel, so transparency would be filled with black.

How do I crop an image into a square (1:1)?

Drop your image, click the 1:1 aspect preset, and the crop box snaps to a perfect square. Drag it into position or drag a corner to resize — the box stays square at every size. The pixel readout confirms the exact width × height before you download.

Does cropping reduce image quality?

No. Cropping just selects a region — pixels inside the box are copied at full original resolution and quality. The output only has fewer pixels because the area outside the box is removed. Exporting as PNG guarantees no additional compression loss.

Can I crop to an exact pixel size?

Yes, in two passes if needed: crop roughly first, note the readout, then re-drop the result and fine-tune with a preset. For common ratios the presets give exact proportions — e.g. a 1080 px-wide 9:16 crop reads exactly 1080 × 1920 when the box spans the full height.
