Image Cropper

Drag a selection over your image — or type exact pixel coordinates — and crop it at full resolution. Aspect-ratio presets keep the selection locked to 1:1, 4:3, 16:9 or 3:2. Everything runs on a canvas in your browser.

How this image cropper works

Drop in an image and it appears on a canvas scaled to fit the panel, with the whole frame selected. Drag anywhere to draw a new selection, drag inside it to move it, or pull any of the eight handles to resize it — the area outside dims so you can judge the composition — and the readout shows the selection size in original pixels, not the scaled-down preview, so what you see is exactly what you get. When you crop, the selected region is copied from the source image at its native resolution onto a fresh canvas: pixels are transferred 1:1, never resampled, all locally in your browser.

The aspect presets lock the drag to a fixed ratio, which is the fastest way to hit a target shape: 1:1 for avatars and Instagram, 16:9 for thumbnails and slides, 4:3 or 3:2 for photography. For pixel-perfect work, the X, Y, width and height fields accept typed values and update the selection rectangle live.

Cropping an image step by step

  1. Drop, paste or browse for an image — PNG, JPEG, WebP or GIF.
  2. Pick an aspect preset, or stay on Free.
  3. Drag a selection on the preview — then move it or pull its handles to adjust — or type exact coordinates.
  4. Click Crop image, check the preview, then download.

Crop first, then resize

Cropping and resizing solve different problems: cropping changes what is in the frame, resizing changes how many pixels describe it. Doing them in that order preserves the most detail — crop to the composition you want here, then scale the result to its final dimensions with the Image Resizer, and if the file still needs to be lighter, finish with the Image Compressor.

Frequently asked questions

Is my image uploaded to a server?

No. The image is drawn onto an HTML canvas inside your browser, the selection is copied to a second canvas locally, and the download is generated on your device. Nothing is transmitted or stored, so it is safe for private photos, screenshots and client work.

Does cropping an image lose quality?

No — cropping copies the selected pixels 1:1 from the original at its native resolution, so nothing inside the selection is resampled or softened. The only caveat is re-encoding: a JPEG source is saved as JPEG again (at high quality), which introduces one generation of compression. PNG sources are re-saved losslessly.

How do I crop to exact pixel dimensions?

Use the X, Y, Width and Height fields under the preview. They stay in sync with the drag selection, so you can rough out an area with the mouse and then type precise values — for example X 0, Y 0, Width 1200, Height 630 for an exact social-card crop.

Which aspect ratios do social platforms want?

1:1 works for Instagram feed posts and most profile grids; 4:3 and 3:2 suit classic photo layouts; 16:9 matches YouTube thumbnails, Twitter/X cards and presentation slides. Link-preview images are commonly 1.91:1 (1200×630) — use the numeric fields for that one.
